Anabolic-androgenic steroids (AAS), commonly called steroids or just roids include endogenous (naturally produced by the body), exogenous (of external origin) and synthetic chemicals able to increase muscle and bone mass. These chemicals are responsible for the maintenance and development of several important metabolic processes (in both sexes) and the development of sexually dimorphic secondary sexual characteristics in males.

The administration of supraphysiological amounts (far above what can be produced naturally by the body) of AAS has been proven to greatly increase both the speed and total possible rate and amount of lean tissue growth and recovery from strenuous training; as such, they are often used by athletes, bodybuilders, and security and military personnel to attain these positive effects despite the potential for adverse side effects and their illegal status in many jurisdictions.

Many individuals in the looksmaxxing community also use and advocate using AAS as a looksmaxxing aid. The use of these substances for cosmetic (or other) purposes is also fairly common in the general public, though varying quite a bit by socioeconomic status, gender, age, race, mental health and (potentially) relationship status.[1][2] AAS usage seems particularly common among male users of online dating apps.[3]

History of anabolic steroids as medication[edit | edit source]

Since ancient times, medicine has shown interest in finding the chemical responsible for masculinity, with the intent of producing an elixir capable of increasing sexual function, strength and vitality[4]. Ancient cultures knew the effects of castration before puberty, that are feminine voice, lack of body hair, lack of muscle mass and impossibility to reproduce, so they ascertained that testicles are the source of masculinity in male body. In 1889 the French doctor Brown-Séquard achieved notoriety by reporting that he had “rejuvenated” himself by injections of a fluid prepared from the testicles of guinea pigs and dogs [5]. However, the truth is that testicles produce testosterone without do not store it, so the amount of testosterone inside animal balls is near to zero. Later in 1935, the Dutch chemist Ernst Lanqueur, succeded in isolating 10 milligrams of testosterone from a batch of 100 kilograms of bull testicles. [6]. As soon as the structure of the molecule of testosterone was discovered by Ernst Lanqueur, it became possible to synthetize and produce on large scale synthetic testosterone, starting from molecule occurring in nature like cholestherol and phytosterolds. However there was still an obstacle: when injected, pure testosterone has an extremely short half-life of only 10 minutes and as such is not suited for medical purposes. So after an year of research, scientists created in 1936 testosterone propionate, a modified molecule of testosterone, with an ester attatched to the 17-beta position. As result, the intramuscular administration of propionated testosterone increased the serum levels of testosterone for 1-2 days and it was finally possible administer synthetic anabolic steroids to patients. Later in 1950s John Ziegler, an american physician, developed Dianabol, a new testosterone-derived anabolic steroid. Ziegler was in charge of the health of the American weightlifting team and prescribed Dianabol to the team, as an attempt to surpass the Soviet olympic team who was using testosterone as performance enhancing drug. The american team still lost to the Soviet, but Ziegler, who later regretted creating Dianabol, succeded in creating the drug which is today the most popular oral steroid on black market. In the following years, a great number of anabolic steroids was developed, mainly derived from DHT molecule. A remarkable event was the introduction of Trenbolone in 1963. Initially designed as anabolic agent to increase lean mass of cattle around 60 days before slaughter, Trenbolone is now regarded as the most powerful but dangerous anabolic steroid.

Potential positive effects[edit | edit source]

  • Lean muscle tissue growth and non-muscle tissue growth (water retention, which visually increases the muscle's size and improves strength). On average, it appears the typical long term user of anabolic steroids gains around ~2x the amount of lean tissue compared to if they had reached their genetic limit without using steroids, all other factors (genetics, diet, training etc.) being roughly equal.[7] Yu et al. (2014) found a very large effect size for differences in lean body mass comparing long term steroid users vs. non users who had engaged in dedicated training over a long term (d = 1.98), albeit with the limitations of a very low sample size and no adjustment for height (the steroid users included strongmen, who are often very tall, especially compared to other strength athletes).[8]
  • A potential to (likely slightly) enhance one's ability to gain muscle and recover from exercise, even after heavy used is ceased.[9] This is because AAS usage increases the proliferation of satellite cells in the muscle fibre, which further increase the amount of myonuclei in the cells. A greater amount of myonuclei enhances total muscular hypertrophy, growth rate and recovery.[10] The amount of satellite cells in the muscle fibre has been proven to be a major factor involved in mediating individual responses to resistance training ('good' vs. 'bad' genetics), with a higher number of satellite cells being associated with greatly increased muscle growth in response to strength training.[11]
  • Enhanced strength and muscular endurance.
  • Increased cardiovascular endurance.
  • Deeper, more masculine voice (in rare instances).
  • Increased libido and erectile potency.
  • Increased focus, aggression and drive (anecdotal report of some users).
  • In what could be viewed as a positive or negative effect based on one's circumstances, a long enough AAS usage also results in nearly complete infertility in most men. This is typically reversible after several months of ceasing AAS usage. Some men appear more resilient to this effect, as they require concomitant administration of progestins for this effect to be apparent (though these doses are much lower than what is typical for recreational steroid users).[12]

Potential negative effects[edit | edit source]

  • Acne.
  • Accelerated male-pattern baldness among those genetically prone to experiencing this.
  • Body hair growth.
  • Mood-swings and depression.
  • Increased blood pressure.
  • Liver toxicity (most pronounced among 17α-alkylated AAS. This includes the majority of orally administered AAS, apart from oxandrolone, which, despite being a 17α-alkylated AAS, is somewhat milder in this regard, potentially due to differences in this drug's metabolism compared to others of its class).[13]
  • Gynecomastia (breast tissue growth, which can be permanent if not swiftly treated).
  • Natural testosterone suppression. In extreme and rare cases this can apparently result in permanent shutdown of the HPTA axis, thus resulting in AAS induced hypogonadism. This typically necessitatates the permanent use of exogenous hormones to mitigate the symptoms of low testosterone levels.
  • Increased risk of cardiovascular failure, especially when used in high amounts and over the long term. Likely attributable to the increase in hematocrit levels that follow prolonged AAS usage (thus thickening the blood and increasing the risk of cardiac infractions) and possibly due to the negative effects AAS have on levels of arterial plaque.
  • Potentially negative neurological changes with long term and/or abusive use (observational research only).[14]
  • Potential for physiological addiction, due to the administration of AAS having the potential to alter the brains endogenous dopaminergic reward system, in a similar fashion to the process of addiction to other illicit substances (rodent studies only).[15]
  • Low libido and erectile dysfunction. This seems to be a rare effect limited to users who take large doses of weakly androgenic AAS such as nandrolone decanoate without taking more androgenic compounds concurrently, as clinical use of the drug has not generally found such effects.[16] Hence, this side effect is commonly referred to as "deca dick". [17]
    The cause of this particular side effect is unknown, but it is commonly believed to be due to a combination of the strong suppression of endogenous testosterone production caused by such compounds together with their level of androgenicity being insufficient to support normal libido in some cases. The long half life of nandrolone decanoate may also play a role, as the drug takes a long time to build up in the body, possibly leading to a lack of sufficient androgenic activity in the body during this "build-up period". Nandrolone has a much lower androgenic effect than testosterone due to it metabolizing via the 5-α-reductase enzyme to DHN (5α-Dihydronandrolone) instead of DHT (dihydrotestosterone).[18] As such, it may compete with DHT for access to the androgen receptor at a lower affinity, possibly leading to a reduction in androgenicity in some bodily tissues.[19] To prevent this side effect, many users advise running at least a small dose of testosterone with nandrolone to prevent this effect if needed.[20]

Side effect prevention[edit | edit source]

Androgenic side-effects[edit | edit source]

Anabolic steroid users commonly take 5-α-reductase inhibitors such as finasteride or dutasteride to prevent hair loss (this will only be effective in the case of androgens that are converted via 5-α reductase to DHT, such as testosterone). It is important to note that this will not work in users who are particularly sensitive to the hair-loss related effects of androgens, as even weak androgens can still exert some direct negative effect on the hair growth cycle among these individuals. Topical compounds such as minoxidil (Rogaine) are also used in less severe cases.

Sexual hormones regulate the activity of the sebaceous glands. A supraphysiological level of anabolic steroids alters the sebaceous systems, and increases the activity of the sebaceous glands leading to a higher risk of acne, for people prone to this disease. Meanwhile, estrogens reduce the activity of the sebaceous glands and reduce acne, this is why progestin-estrogen birth control pill is prescribed to women for the reason of treating acne. In case the user of anabolic steroids experiences acne as a side effect, they may utilize topical anti-acne treatments such as retinoids (substances derived from, or chemically related to vitamin A), benzoyl peroxide, or they can take oral retinoids such as isotretinoin in the most severe cases (as these drugs can have harsh side effects).

Estrogenic/progesteronic side effects[edit | edit source]

As many AAS exhibit the potential to be aromatized by the enzyme aromatase into estrogen (or other related compounds), the concurrent administration of drugs with anti-estrogen properties is pursued by those sensitive to the sometimes negative effects of elevated levels of these hormones. It is important to note that these ancillary drugs themselves often exhibit the potential to cause adverse side effects.[21][22] There is some mechanistic evidence that some AAS (such as oxymetholone or trenbolone) can directly act on the estrogen receptor (ER) or the progesterone receptor (PR) by themselves, thus leading to the potential to induce these kinds of side effects in sensitive individuals, without elevated systematic levels of estrogens or progestins being at play directly. Therefore, the choice of AAS naturally influences what ancillary drugs users select in the attempt of ameliorating these unwanted side effects.

Aromatase inhibitors (AIs) or selective-estrogen receptor modulators (SERMS) are commonly used to prevent gynecomastia (breast tissue growth) during the cycle. Many users prefer the latter class of drugs as these substances are selective in how they affect the utilization of estrogen by the body, preserving some of the positive effects of estrogen (such as on mood, libido and bone tissue) while inhibiting the agonism of the estrogen receptors in the breast tissue by the hormone, thus preventing gynecomastia in many cases. Aromatase inhibitors strongly inhibit the bodies' production of estrogen and are thus generally recommended by users only in emergencies related to estrogenic side-effects, to have 'on hand' as needed.

It is also important to note that, in some cases, gynecomastia can occur in some sensitive individuals even when levels of estrogens are controlled, likely owing to the ability of some AAS (most notably nandrolone and trenbolone) to act as agonists of the progesterone receptor (PR), which is theorized to potentiate the effects of estrogen in the breast tissue. In these cases, AI usage alone would not suffice to control gynecomastia, and SERM usage may be necessary to block estrogen's local effects on the breast tissue. It has been found that progesterone and estrogen stimulate the production of IGF-1 (insulin-like growth factor 1) and that IGF-1 interacts with compounds that have estrogenic and progesteronic effects in mediating breast growth. Progesteronic compounds may also have direct stimulatory effects on the breast tissue, mainly via stimulating alveolar (breast tissue ducts) development.[23] Thus, individuals who are very sensitive to developing gynecomastia often limit their use of highly progesteronic and estrogenic compounds or avoid them altogether.

Some users that are sensitive to estrogen-related side-effects of AAS also forgo the usage of SERMS or AIs during the cycle and instead utilize lighter aromatizable compounds together with the AAS drostanolone (commonly referred to by the tradename for drostanolone propionate, Masteron), which does not aromatize to estrogen and also seems to exhibit some peculiar inhibitory effects on the growth of breast tissue that may be unique to this specific AAS.[24] The drug was previously administered to female breast cancer patients before the development of therapies that presented no risk of virilization related side-effects (hence the brand name's reference to breasts, the -mast prefix) namely AIs and SERMs.

Some steroids such as trenbolone, oxandrolone, stanozolol and metenolone enanthate (Primobolan) are not acted upon by the enzyme aromatase and therefore often do not require the administration of agents such as SERMs or aromatase inhibitors to negate any potential estrogenic or progestational effects (though the latter has been reported anecdotally among some users of trenbolone, and trenbolone indeed exhibits a high affinity for the progesterone receptor). However, suppose these substances are taken without aromatizing steroids. In that case, this will result in low or non-existent estrogen levels, which can often lead to several highly unpleasant side effects.

In some cases, these side effects are deliberately endured by users, such as when a pre-contest bodybuilder limits his anabolic steroid usage to these compounds for them to exert a 'hardening' effect on the muscles and increase muscular definition (due to the more exclusive lean tissue promoting effects of these steroids due to the lack of water retention experienced when taking them compared to more estrogenic/progesteronic substances).

General side effects[edit | edit source]

Sylimarine (milk thistle), TUDCA (tauroursodeoxycholic acid… ), NAC (N-acetyl cysteine) and other hepatoprotective compounds are often used in an attempt to prevent the potential for liver damage owing to the use of certain types of hepatotoxic AAS (though it is unclear how effective this is in the long term, many chronic users strictly limit their usage of liver toxic 17α-alkylated oral steroids due to this reason or restrict their usage to more mild compounds such as oxandrolone).

In terms of mitigating the potentially negative long-term effects on the cardiovascular system possibly associated with chronic AAS usage,[25] it is likely that only harm-reduction practices such as limiting one's usage to less harsh substances such as testosterone, nandrolone decanoate, and Primobolan and limiting the dosages of these substances would prove efficacious in the long term here. Following a regular program of cardiovascular exercise, eating a whole-food-based diet that excludes hydrogenated oils, added sugar, and ceasing any other activities that are risk-factors for cardiovascular disease, such as smoking, would likely be recommended. The supplementation of ω-3 fatty acids (fish oil) and garlic (and other substances that improve endothelial function in general) may also aid in maintaining healthy cardiovascular function, though evidence for this not overly robust.[26][27]

As the administration of even modest amounts of exogenous AAS is enough to cause substantial or total suppression of endogenous testosterone in most men, it is considered necessary by most users to implement PCT (post cycle therapy) after the completion of a steroid 'cycle' to reestablish the endogenous production of testosterone, as without this therapy, it takes a long-time for the HPT axis (hypothalamic–pituitary–thyroid axis) to recover from the negative feedback induced suppression of the gonadal function induced by the prolonged administration of AAS, leaving one prone to the negative effects of hypogonadism (low T). To this purpose, SERMS and HCG (human chorionic gonadotropin) are commonly administered to restore/maintain reproductive ability and the general function of the gonads during/after a steroid cycle (the latter is typically used as an adjunct, the former sometimes as monotherapy or, more commonly, using a combination of different SERMS).

Steroid usage among male population[edit | edit source]

According to an online survey on a sample of American online dating users, 36.4% of male users reporting using steroids, as opposed to only 3.8% of non-online dating men who reported AAS use.[28] This suggests that due to the highly competitive nature of online dating for men, men are being driven to increasingly extreme measures to improve their looks in order to compete. Steroid usage is widespread in PSL community because users often consider a lean muscular body a key to attract women.

Anabolic vs androgenic steroids[edit | edit source]

The term anabolic refers to the so-called "anabolic ratio" of the various androgenic substances. Substances developed for medical use were specially designed to have less androgenic activity on tissues such as the scalp, the prostrate, the skin and so forth, and greater androgenic activity on the muscle cells. The idea was that this would reduce the harsh side-effects many abusers of the newly-developed injectable testosterone were experiencing, such as members of the American Olympic weight lifting team at the time, via the development of synthetic alternatives that would be more targeting in terms of maximizing the anabolic effects of the drugs on the skeletal muscle tissue and minimizing the (often) adverse effects that resulted from these drugs agonism of the androgen receptor in other bodily tissues.

The ratio of the androgenic to anabolic effects of these new drugs was typically tested by administering AAS to castrated rodents (though primates were used in some studies). The resulting tissue growth was them compared by examining the levator ani muscle (thought to be representative of the effects of these compounds on the skeletal muscle tissue) vs. reproductive system tissues such as the seminal vesicles, and comparing this growth to that produced by the administration of testosterone, the reference compound.

From this method, a ratio of anabolic/androgenic effects vs testosterone was derived for many androgens. However, this procedure has been criticized as lacking scientific rigor due to the dissimilarity between the supposed levator ani muscle targeted in rat studies as compared to the human counterpart to the muscle. The levator ani was likely not the ideal muscle to utilize for this purpose. It is part of the rodent reproductive system and is thus not strictly homologous with skeletal muscle tissue in other mammals, such as humans. In fact, it was subsequently 'discovered' that this muscle is completely different to the levator ani in humans, with this muscle being properly named the dorsal bulbocavernosus, a muscle unique to rodents. This finding led to claims that this method of determining the relative anabolic/androgenic effects of the various AAS was completely useless, with it being asserted to data was lacking in regards to whether the hypertrophy of this muscle was strongly correlated with global nitrogen retention at all.[29]

However, there is biochemical evidence that the levator ani muscle does exhibit several characteristics that make it similar to skeletal muscle tissue for this purpose; for example, it has been discovered that the androgen receptor density in rodent prostate tissues is many times greater than in this muscle and that 5α-reductase activity (the compound that converts testosterone to DHT and is thus primarily responsible for the expression of male secondary sexual characteristics) is much lower in the levator ani as compared to the prostatic tissue of rodents, thus making the levator ani muscles similar to the skeletal muscle tissue in these regards, and therefore likely a decent proxy for skeletal muscle tissue.[30]

Another major issue with these studies is that many of them were quite brief (for reasons of expediency). The subjects were sacrificed well before the differential effects of AAS on the body's various tissues were fully apparent. As some androgens produce their androgenic effects on reproductive tissues such as the seminal vesicles more slowly than they do on the skeletal muscles, this may have lead to the anabolic/androgenic ratios of several of these compounds being distorted in favor of overstating anabolic effects and understating androgenic effects that may be more pronounced with prolonged usages.

This would mean that some of these compounds' low androgenic ratios would tend to understate their risk of producing the side-effects often associated with greater androgenicity, such as hair loss, prostate enlargement, acne and possibly aggression and mood swings.

It is important to note that even so-called 'anabolic steroids' can still exert strong androgenic effects (and therefore lead to the side effects associated with AAS use) in high enough doses or in those who are especially sensitive to their effects. The long quest of chemists (mainly driven by the desire to create AAS that could be safely administered to women and children) to completely disassociate the anabolic and androgen effects of synthetic AAS failed, with the research in this area now moving toward SARMs, which appear to have the promise of achieving the goal of substantial disassociation between these effects.

It is also important to note that not all androgenic effects are undesirable. The androgenic actions of AAS are needed to maintain a healthy libido, a stable mood, and other desirable effects. It is also commonly anecdotally asserted by many AAS users that cycles that only utilize relatively weak androgens tend to be less productive in terms of muscle growth as compared to those that use or add compounds with stronger androgenic effects. What substances a user utilizes tends to be driven by their goals, tolerance for side effects, and sensitivity to the side effects of AAS use, with those prone to experiencing strong androgen-related side-effects (such as acne and hair-loss) tending to avoid strong androgenic substances and those with a sensitivity to estrogenic side effects (such as gynecomastia and harsh water retention) avoiding the particularly estrogenic substances and so forth.

The following is a table listing the androgenic/anabolic ratios of various AAS, as derived from early animal studies (largely conducted on castrated rodents) that attempted to approximate the varying targeted effects of these compounds on the skeletal muscle tissue as compared to the reproductive tissues (used as a proxy of androgenic activity elsewhere in the body), using the methodology described above:

Unique effects of various compounds[edit | edit source]

Among users of anabolic steroids, there are various claims about the distinctive effects of one particular compound or another that makes certain compounds more suited for specific performance/physique goals. These claims are generally based on trial and error and anecdotal experiences with the use of these substances. High-quality human trials regarding the effects of anabolic steroids are limited in the case of many of these drugs. Some of the claims as to the specific properties of these substances are listed below:

Trenbolone: The anabolic steroid trenbolone acetate is commonly believed to have potent fat-loss effects.[31] While this seems to be an effect of most anabolic steroids (in combination with a correct diet), fat loss is claimed to be particularly potent and noticeable with tren. As trenbolone has never been approved for human administration and has never been tested in clinical trials among humans, it is hard to find more formal evidence of this claim. Research in animal models has provided some evidence for the fat-loss effects of trenbolone, which improves nutrient partitioning (via greater insulin sensitivity) and reduces adiposity in rats.[32] Trenbolone acetate is also commonly used in the cattle industry to improve feed efficiency. However, it does not seem to have strong effects on the leanness of the meat (it increases the utilization of the calories, with the proportion of fat and lean mass being unchanged).[33] As feedlot cattle are often fed estradiol to bulk them up (which promotes fat gain), this suggests that trenbolone's 'cutting' benefits may accrue mainly because this compound does not aromatize (convert) to estrogen in the body. This lack of capacity for aromatization shifts the ratio of hormones in the body strongly towards androgenicity, promoting a leaner, harder physique over time when tren is not used together with large doses of aromatizable compounds (such as testosterone). However, this would not be a benefit unique to tren but one found among all non-aromatizable AAS, though the effect is likely more pronounced in trenbolone due to the extreme potency of the hormone.

Nandrolone decanoate (Deca): Deca is often claimed to have a potent positive effect on the health of joints and connective tissue, with this steroid often being "prescribed" to lifters suffering from chronic injuries. Clinical research has largely backed these claims and found that even a low dose (50 mg every month) is sufficient to treat osteoporosis in women.[34] Other research has found substantial benefits in improving joint mobility and reducing arthritic pain in men.[35]

Masteron: Masteron (Drostanolone) is an AAS claimed to have anti-estrogen effects, which often leads to people advising it to be cycled with other compounds in lieu of a dedicated anti-estrogen like an aromatase inhibitor or a SERM. Drostanolone was indeed used clinically as an anti-estrogen to treat breast cancer before the development of treatments that produced less potential for harsh side effects, such as AIs and SERMs.[36] It did not seem to be highly effective as a treatment for breast cancer, only reducing objective symptoms in a minority of cases,[37] and it is unclear how potent the anti-estrogen effect of the substance is. As such, many steroid users still advise using a dedicated anti-estrogen drug when using large amounts of aromatizable or estrogenic AAS.

Non-steroid anabolic agents[edit | edit source]

Some substances like SARMs (selective androgen receptor modulators), such as LGD-4033, RAD 140 and Ostarine, have been theorized to exert similar effects to anabolic steroids in the scientific literature. However, clinical reports and anecdotal accounts from users of these mainly untested substances indicates the anabolic effects of the current generations of these substances is typically much more modest,[38] at least compared to the administration of the more potent anabolics such as trenbolone, testosterone and oxymetholone. These substances are treated as PEDS (performance-enhancing drugs) by most international sports doping regulatory bodies, with penalties to the athlete when use is discovered being analogous to the penalties that exist for the use of AAS (anabolic-androgenic steroids).[39]

The long-term effects of these novel substances' administration are also understudied, with properly conducted and large scale clinical trials investigating these substances being severely lacking. This is true for many synthetic anabolic steroids also (though not for testosterone, at least in modest doses, and AAS that are still common in clinical use, such as nandrolone decanoate and oxymetholone), many of which were (such as the various varieties of trenbolone, a very popular anabolic steroid among recreation steroid users and athletes due to its potency and dramatic effects of muscle gain and overall body composition) not developed or intended for human use. However, it is important to note that many of these substances have been tested on humans throughout several clinical trials and have previously been approved by regulatory bodies such as the FDA in the United States for medical use in human patients, which is not true for any SARM as of 2021.

Several anabolic agents are not steroids or do not mimic the actions of steroids on the androgen receptor (what SARMs do) such as Cardarine (a PPARδ receptor agonist, often incorrectly labelled a SARM). This research chemical was abandoned by its manufacturer after experiments found that extreme doses of the substance are often carcinogenic in rats.[40]

Insulin, IGF-1 (insulin-like growth factor 1), and HGH (human growth hormone) and its several analogues also have anabolic effects, but don't have a steroidal chemical structure. This different mechanism of effect can give them a synergistic effect with AAS, and it is not uncommon for bodybuilders to administer these substances concurrently with AAS. Clenbuterol, a bronchodilator originally developed to treat asthma, can also exhibit weak to moderate anabolic effects and fat loss promoting properties, together with the more commonly used bronchodilator salbutamol (Ventolin). The anabolic effects of these drugs appear to be mediated by their agonism of the β2-adrenergic receptors of the muscle cells and seem modest in effect based on the results of limited human trials.[41]

Chads[edit | edit source]

Chads have been known to use steroids. It isn't uncommon for popular celebrities to have used heavy and copious amounts to attain physically aesthetic and muscular bodies and appearances. Many notable celebrities such as Ryan Reynolds, Zac Efron, Hugh Jackman, Vin Diesel, Henry Cavil and Tom Hardy have been accused of using anabolic steroids at some stage of their career. Several male video game characters, such as Duke Nukem, have physiques that are impossible to approximate in reality without the use of copious amounts of anabolic substances.

Many of the celebrities listed above have muscular bodies that otherwise would be difficult to achieve without the use of steroids, especially when one considers the amount of lean mass they often gain in short periods to fulfill the requirements of a certain role.

One major indicator of steroid use is when an individual (especially a previously trained one) has a suspiciously large jump in lean mass gains over a narrow window of time (nearly impossible to achieve in natural individuals due to the typical rate of lean mass growth, unless one is recovering from prolonged periods of calorie restriction, which can result in some 'rebound' gains).[42] Very dramatic 'body transformations' such as these are not uncommon in Hollywood. Other indicators include disproportionate development of the deltoids, neck and trapezius muscles, as these muscles exhibit greater androgen receptor density than the other upper body muscles, and thus they are particularly sensitive to the effects of anabolic steroids.

An individual's FFMI (fat-free mass index, or their overall amount of lean body mass in relation to their height) is also an indicator, especially at extremes, however it is important to note that there is significant overlap in FFMI between natural and AAS using athletes,[43] and thus there is no easy threshold of lean mass at which is it possible to ascertain 100% whether or not a person has used steroids, apart from obvious extremes.
