Chemical structure of the natural anabolic
Anabolic steroid

From Wikipedia, the free encyclopedia

Anabolic androgenic steroids (AAS) are a class of natural and synthetic steroid hormones that promote cell growth and division, resulting in growth of several types of tissues, especially muscle and bone. Different anabolic androgenic steroids have varying combinations of androgenic and anabolic properties, and are often referred to in medical texts as AAS (anabolic/androgenic steroids). Anabolism is the metabolic process that builds larger molecules from smaller ones.

Anabolic Steroids were first discovered in the early 1930’s and since have been used for numerous medical purposes including stimulation of bone growth, appetite, puberty, and muscle growth. The most wide spread use of anabolic steroids is their use for chronic wasting conditions including cancer and AIDS. Anabolic steroids can produce numerous physiological effects including increased protein synthesis, muscle mass, strength, appetite and bone growth. Anabolic steroids have also been associated with numerous side effects when administered in excessive doses and these include elevated cholesterol (increase in LDL, decreased HDL levels), acne, elevated blood pressure, hepatotoxicity, and alterations in left ventricle morphology.

Today anabolic steroids are the center of a lot of controversy concerning their widespread use in numerous sports and their purported side effects. While there are numerous health issues associated with excessive anabolic steroid use, there is also a substantial amount of propaganda, junk science and misconceptions concerning their use. Anabolic steroids are controlled in a few countries including the United States where they are listed as Schedule III in the Controlled Substances Act as well as Canada and Britain who also have laws controlling their use and distribution.

Anabolic and virilizing effects

Anabolic androgenic steroids produce both anabolic and virilization (also known as androgenic) effects. Most anabolic steroids work in two simultaneous ways. First, they work by binding the androgen receptor and increasing protein synthesis. Second, they also reduce recovery time by blocking the effects of the stress hormone, cortisol, on muscle tissue. As a result, catabolism of the body’s muscle mass is greatly reduced.

Examples of anabolic effects:

Examples of virilizing/androgenic effects:

Possible unwanted side effects

Many androgens are metabolized to estrogenic compounds which bind to estrogen receptors, producing additional (usually) unwanted effects:

Male-specific side effects

  • GynecomastiaBreast development in males. It is usually due to high levels of circulating estrogen. These high levels are the result of the increased level of conversion of testosterone to estrogen via the aromatase enzyme.
  • Reduced sexual function and temporary infertility[11][12][13]
  • Testicular atrophy – Temporary side effect that is due to decreases in natural testosterone levels. The size of the testicles usually return to normal within a few weeks of discontinuing anabolic steroid use.[14]

Female-specific side effects

Adolescent-specific side effects

  • Stunted growth – Abuse of the agents may prematurely stop the lengthening of bones (premature epiphyseal fusion through increased estrogen)
  • Accelerated bone maturation
  • Slight beard growth

An ideal anabolic steroid (a hormone with purely anabolic effects and no virilizing or other side effects) has been widely sought. Many synthetic anabolic steroids have been developed in an attempt to find molecules that produced a higher degree of anabolic rather than virilizing effects. Unfortunately, the most effective steroids known for increasing lean body mass also have the strongest androgenic characteristics.

Various anabolic steroids and
related compounds
Medical uses

Anabolic steroids were tried by physicians for many purposes from the discovery of synthetic testosterone in the 1930s to the 1950s with varying success. One of the initial medical uses of steroids was treatment of chronic wasting, such as was experienced by Nazi concentration camp prisoners and prisoners of war. During World War II, German scientists worked on synthesizing other anabolic steroids, and ran experiments on human prisoners, as well as with their own soldiers. They had hoped to increase the aggressive tendencies of their troops. Adolf Hitler’s own physician reported that Hitler had been given testosterone derivative injections to treat various ailments. [15]

  • Bone marrow stimulation: For decades, anabolic steroids were the mainstay of therapy for hypoplastic anemias not due to nutrient deficiency, especially aplastic anemia. Anabolic steroids are slowly being replaced by synthetic protein hormones (such as epoetin alfa) that selectively stimulate growth of blood cell precursors.
  • Growth stimulation: Anabolic steroids were used heavily by pediatric endocrinologists for children with growth failure from the 1960s through the 1980s. Availability of synthetic growth hormone and increasing social stigmatization of anabolic steroids led to discontinuation of this use.
  • Stimulation of appetite and preservation and increase of muscle mass: Anabolic steroids have been given to people with chronic wasting conditions such as cancer and AIDS.[16][17]
  • Induction of male puberty: Androgens are given to many boys distressed about extreme delay of puberty. Testosterone is now nearly the only androgen used for this purpose but synthetic anabolic steroids were often used prior to the 1980s.
  • Testosterone enanthate may prove to be a useful, safe, reversible, effective method of male hormonal contraception in the near future.[18][19]
  • Used for age related problems in elderly people. Anabolic Steroids have been shown to help in many age related problems in the elderly.[20]
  • Used in hormone replacement therapy for men with low levels of testosterone. (see hypogonadism)
  • Used for gender dysmorphia: whereby secondary male characteristics (puberty) are initiated in female-to-male diagnosed patients. Most commonly used testosterone derivatives are Sustanon and Testosterone Enanthate which cause the voice to deepen, increased bone and muscle mass, facial hair, increased levels of red blood cells and clitoral enlargement.


Medical Disclaimer

There are two common routes for the administration of anabolic steroids: oral (for steroids in pill form) and injectable (this category includes both oil-dissolved and water-dissolved steroids.) Also, transdermal (through the skin) administration via cremes or transdermal patches has become popular in the last several years.

Anabolic steroids should never be injected by persons unfamiliar with safe injection sites and practices or without first consulting a doctor. Injectable steroids are commonly injected IM (intramuscularly) with 1-1.5″ 18-25 gauge needles. Care must be taken to maintain cleanliness when injecting. Infection and disease can result if careless procedures are used. Care must also be taken when selecting an injection site. Injections into nerves will be extremely painful and dangerous. Injection into vessels is dangerous as well, as this can cause an embolism or other complications. Common injection sites include the shoulders, outer thighs, and buttocks. Note however, that the sciatic nerve runs right up the back of each leg and up the middle of both buttocks. The triceps, biceps and latissumus dorsi also have been used, however, this practice can be dangerous. Blood vessels are abundant in these and other areas. Common amounts used at any one time are typically on the order of a few tens of mg/day for oral steroids, to several hundred mg/week for injectable steroids. As with any drug, increasing the dosage increases the risk of the above side effects.

Use and abuse in sports

Anabolic steroids have been used by men and women in many different kinds of professional sports (track and field, weightlifting, bodybuilding, shot put, cycling, baseball, wrestling, Mixed Martial Arts, boxing, football, etc.) to attain a competitive edge or to assist in recovery from injury. Steroid use to obtain competitive advantage is prohibited by the rules of the governing bodies of many sports. However, steroids are also used by many non-professional athletes to enhance physical performance, and are also widely used by amateur bodybuilders to enhance physical appearance. Unfortunately, these powerful compounds are also used by adolescents.

According to the 1999 Monitoring the Future study, the percentage of eighth, tenth, and twelfth graders in the United States who reported using steroids at least once in their lives increased steadily over the preceding four years (an average of 1.8% in 1996, 2.1% in 1997, 2.3% in 1998, and 2.8% in 1999). In addition, steroid use to enhance athletic performance is no longer limited to high school males: a 1998 Pennsylvania State University study found that 175,000 high school girls nationwide reported taking steroids at least once in their lifetime. The National Institute on Drug Abuse found that 3.4% of all high school seniors report using steroids at least once in 2005. Nearly 2% of 8th graders admitted to using steroids.

Minimizing the side effects

Typically, bodybuilders, athletes and sportsmen who use anabolic steroids try to minimize the negative side effects. For example, users may increase their amount of cardiovascular exercise to help negate the effects of left ventricle hypertrophy.

Some androgens will aromatise and convert to estrogen, potentially causing some combination of the side effects listed above. During a steroid cycle users may take an aromatase inhibitor and/or a SERM; these drugs affect aromatisation and estrogen receptor binding respectively. The SERM tamoxifen, is of particular interest as it prevents binding to the estrogen recepetor in the breast, reducing the risk of gynecomastia.[21]

Furthermore, to combat the natural testosterone suppression and to restore proper HPTA function, what is known as ‘post-cycle therapy‘ (PCT) is self prescribed. PCT takes place after the course of anabolic steroids. It typically consists of a combination of the following drugs depending on which protocol is used:

The aim of PCT is to return the body’s endogenous hormonal balance to its original state within the shortest space of time.

Those prone to premature hairloss due to steroid use have been known to take the prescription drug finasteride for prolonged periods of time. Finasteride reduces the conversion of testosterone to DHT, the latter having much higher potency for alopecia. Finasteride is useless in the cases when steroid is not converted into a more androgenic derivative. Finasteride is also used as a masking agent by those who are subject to steroid testing.

Since Anabolic steroids can be toxic to the liver or can cause increases in blood pressure or cholesterol, many users consider it ideal get frequent blood work tests and blood pressure tests to make sure their blood pressure or cholesterol are still within normal levels. Since Anabolic steroids can increase cholesterol they increase the risk for heart attack in users.[22] So it is generally considered mandatory for all users to get blood work while using anabolic steroids.

Popular misconceptions

Anabolic steroids like many other drugs have been at the center of a lot of controversy and because of this there are many popular misconceptions and myths concerning their purported effects and side effects. As with many infamous drugs in popular culture the misconceptions relating to anabolic steroids have likely arisen from misunderstandings of actual side effects of anabolic steroids, one such example might include the myth that anabolic steroids can ‘shrink’ ones penis. It is likely that this myth came from the real side effect of anabolic steroids known as testicular atrophy in which the use of anabolic steroids will cause natural testosterone levels to decrease, thus reducing testicle size. This side effect is temporary and testicles return to normal once use is stopped and natural testosterone levels return to normal. [23]

Another common misconceptions purveyed in popular culture and the media include the myth that anabolic steroids are highly dangerous and users mortality rates are high. Anabolic steroids are used widely in the medical field without any serious health risks to users[24][25][26] and no scientific evidence has shown any long term serious health defects from correct use of anabolic steroids. While risk of death is present in many drugs, the risk of premature death from use of anabolic steroids seems to be extremely low.[27] It is possible this myth gained popularity from claims that Lyle Alzado died from brain cancer caused by anabolic steroids. Alzado himself had claimed that his cancer was caused by anabolic steroids. However, there is no medical evidence anabolic steroids can cause brain cancer and Alzado’s own doctors admitted anabolic steroids had nothing to do with his death.[28]

More myths relating to purported side effects include claims that anabolic steroids have caused many teenagers to commit suicide. While lower levels of testosterone have been known to cause depression, and ending a steroid cycle is known to result in temporarily lower testosterone levels, the claim that anabolic steroids are responsible for specific suicides among teenagers is highly questionable. In the United states the estimated use of anabolic steroids among high school students was 2.8% in 1999. On the other hand, in the year 2000 in the United States, suicide was the third leading cause of death among 15- to 24-year-olds.[29] With the suicide rate this high among teenagers, concluding anabolic steroids are responsible for the suicides of teenagers who happened to be taking them prior to committing suicide is a Post hoc logical fallacy. Also, even though teen bodybuilders have been using steroids since at least the early 1960’s, only a few cases suggesting a link between steroids and suicide have been reported in the medical literature. [30]

One of the most common misconceptions regarding the side effects of anabolic steroids is known as ‘roid rage’. There seems to be little or no evidence such a condition actually exists. Most studies done on «angry behavior» and anabolic steroid use show no psychological effect, implying that either «roid rage» doesn’t exist or that anabolic steroids effects on aggression are too small to be measured. Many scientists and medical professionals conclude anabolic steroids have no real effect on increased angry behavior.[31] [32] [33][34][35]

Arnold Schwarzenegger is the victim of yet another myth regarding the purported side effects of anabolic steroids. Arnold Schwarzenegger has admitted to using anabolic steroids during his bodybuilding career for many years [36] and in 1997 he went in for surgery to correct a defect relating to his heart. So many have concluded that this was due to anabolic steroids. This claim is false. Arnold Schwarzenegger was born with a genetic defect in which his heart only had a bicuspid aortic valve. It was a congenital disorder meaning he was born with it. Normal hearts have 3 cusps. However Arnold Schwarzenegger had only 2 cusps which can occasionally cause problems, especially later in life.[37]

Illegal trade in anabolic steroids

Since anabolic steroids are often produced in different countries than in which they are distributed, they must be smuggled across international borders. Like most significant smuggling operations, sophisticated organized crime is involved, often in conjunction with other smuggling efforts (including other illegal drugs). Unlike psychoactive recreational drugs such as cannabis and heroin, there have not been many high profile cases of individual smugglers of anabolic steroids being caught. The majority of those using illegally obtain the drugs via this black market [38] [39] , and more specifically, pharmacists, veterinarians, and physicians. Anabolic Steroids purchased through the Black Market may be counterfeit, or originally manufactured for veterinary applications. Which in and of itself isn’t dangerous except for the fact they are sometimes produced and handled in cruder and less sterile environments.


Anabolic steroids need sophisticated pharmaceutical processes and equipment to produce, so they are produced by legitimate pharmaceutical companies or underground laboratories with large overheads. Common problems associated with illegal drug trades, such as chemical substitutions, cutting, and diluting, affect illegal anabolic steroids such that when it reaches distribution the quality may be questionable or possibly dangerous.

In the 1990s most US producers such as Ciba, Searle and Syntex stopped making and marketing anabolic steroids within the US. However, in many other regions, particularly Eastern Europe, they are still produced in quantity. European anabolic steroids are the source of most medical grade anabolic steroids sold illegally in North America. However, anabolic steroids are still in wider use for veterinary purposes, and many illegal anabolic steroids are actually veterinary grade.


In the United States and Canada, steroids are purchased just like any illegal drug through dealers who are able to obtain the drugs from a number of sources, although most users would prefer to buy from legitimate sources but cannot because of the restrictive laws against steroid possession. Counterfeit steroids are a common solution to the lack of legal availability in the United States and Canada, although black-market importation continues from Mexico, Thailand and other countries where steroids are more easily available and, in many countries, not illegal at all. Many people produce fake steroids and attempt to sell them over the internet which causes a wide variety of health concerns.

Most illicit anabolic steroids are now sold at gyms, competitions, and through the mail. For the most part, these substances are smuggled into the United States. In addition, a significant number of counterfeit products are sold as anabolic steroids, particularly via mail order from websites posing as overseas pharmacies. In addition to the recreational use of anabolic steroids, users in Great Britain have been shown to consume illicit drugs as well, such as cannabis, and cocaine.


Comments on professional athletes in ancient Greece suggest that a wide variety of natural steroidal substances were used to promote androgenic and anabolic growth. These may have ranged from testicular extracts to plant materials. Traditional medicine in general, in the West as well as in contemporary Asian medicine, has a wide pharmacopeia of substances intended to promote virility and masculine traits, though not entirely oriented towards muscle growth and athletic ability so much as sexual performance. In Chinese traditional medicine, substances such as deer antler, tiger bone, bear gall bladder, ginseng and other roots and much more are all primarily consumed and were thought to bolster the male organism. Though there is no science behind these claims.

Modern pharmaceutical anabolic steroids are believed to have been inadvertently discovered by German scientists in the early 1930s, but at the time the discovery was not considered significant enough to warrant further study. The first known reference to an anabolic steroid in a US weightlifting/bodybuilding magazine is testosterone propinate in a letter to the editor in Strength and Health magazine in 1938. In the 1950s, scientific interest was rekindled, and methandrostenolone (Dianabol) was approved for use in the United States by the federal Food and Drug Administration in 1958 after promising trials had been conducted in other countries.

Throughout the ’50s, ’60s, ’70s and even ’80s there was doubt Anabolic Steroids even had a real effect. In a 1972 study [44], participants were informed they would receive injections of anabolic steroids on a daily basis, but instead had actually been give placebo. They reportedly could not tell the difference, and the perceived performance enhancement was similar to that of subjects taking the real anabolic compounds. This study had many flaws including inconsistent controls and insignificant doses. According to Geraline Lin, a researcher for the National Institute on Drug Abuse, at the time of the books’ publishing in 1996, the results of the study remained unchallenged for 18 years.[45]

In the 1996 study mentioned above which was founded by the NIH it examined the effect of high doses of testosterone enanthate (600 mg/week intramuscularly for 10 weeks). The results showed a clear increase in muscle mass and decrease in fat mass in those who took the testosterone opposed to the placebo. No adverse reactions were noted.[46]

The U.S. Congress in the Anabolic Steroid Control Act of 1990 placed anabolic steroids into Schedule III of the Controlled Substances Act (CSA). The CSA defines anabolic steroids as any drug or hormonal substance chemically and pharmacologically related to testosterone (other than estrogens, progestins, and corticosteroids) that promotes muscle growth.

By the early 1990s after anabolic steroids were scheduled in the United States several pharmaceutical companies stopped manufacturing or marketing the products in the United States, including Ciba, Searle, Syntex and others.

In addition, an entire market for counterfeit drugs emerged at this time. Never seen in the previous 30 years of their availability on the U.S. market, computers and scanning technology made the ease of counterfeiting legitimate products by utilizing their original label design, and the market was flooded with products that contained everything from mere vegetable oil to toxic substances which unsuspecting users injected into themselves, of which some died as a result of blood poisoning, methanol poisoning or subcutaneous abscess.

On January 20, 2005, the Anabolic Steroid Control Act of 2004 took effect, amending the Controlled Substance Act to place both anabolic steroids and prohormones on a list of controlled substances, making possession of the banned substances without a prescription a federal crime.[47]

Movement for decriminalization

Anabolic steroids are Schedule III controlled substances in the United States and are strictly regulated in some other countries. (It is perhaps worth noting that anabolic steroids are readily available without a prescription in some other countries such as Mexico, Germany, and Thailand.) However, since the U.S. Congress passed the Anabolic Steroid Control Act of 1990, a small movement has arisen that is highly critical of current laws concerning anabolic steroids. On June 21, 2005 Real Sports aired a segment discussing the legality and prohibition of anabolic steroids in America.[48] The show featured Dr. Gary Wadler, chairman of the U.S. Anti- Doping Agency and a prominent anti-steroid activist. When pressed for scientific evidence by correspondent Armen Keteyian that anabolic steroids are as ‘highly fatal’ as he claims, Wadler admitted there was no evidence. Gumbel concluded the ‘hoopla’ concerning the dangers of anabolic steroids in the media was ‘all smoke and no fire.’ The show also featured John Romano, a pro-steroid activist who authors ‘The Romano Factor,’ a pro-steroid column for bodybuilding magazine Muscular Development.[49]

In July 2005 Philip Sweitzer, an Attorney and Author, published an open letter to the Members of the House Committee on Government Reform, and the Senate Committee on Commerce et al. In it he criticized lawmakers’ actions in scheduling anabolic steroids, as well as criticized their ‘disregard of scientific reality for symbolic effect.’ He also pleaded for the consideration of the decriminalization of anabolic steroids and asked for a new policy direction.[50] The U.S. government’s position since the late 1980’s has been and continues to be that the risks of steroid use are too great to allow them to be decriminalized or unregulated.
