Anabolic Steroids - Abuse, Side Effects and Safety
The adverse effects associated with anabolic-androgenic steroids are dependent on the age and sex of the user, the amount used and the duration of use. More detail and supporting information is in the main article. The kidney damage in the bodybuilders has similarities to that seen in morbidly obese patients, but appears to be even more severe. The proper term for these compounds is anabolic-androgenic steroids. Data on long-term side effects primarily come from case reports and not from well-controlled, long-term epidemiological studies, which might be reliable. As a result, AAS users may get misdiagnosed by a psychiatrist not told about their habit. Hoffman and Nicholas A.
Are Anabolic Steroids Prohibited in Sports?
Steroid hormones work by stimulation of receptor molecules in muscle cells, which activate specific genes to produce proteins see Figure 1. Therefore, long after you gave them up you may develop side effects. Causes and treatment of inner thigh pain. We mostly hear about them being used as performance enhancing drugs when professional athletes test positive for using the substance. Retrieved 1 December
Common street names that are used to refer to anabolic steroids may include:. Abuse of anabolic steroids can occur in any age group, but statistics on their abuse is difficult to quantitate because many surveys on drug abuse do not include steroids.
According to the National Institute on Drug Abuse NIDA , scientific evidence indicates that anabolic steroid abuse among athletes may range between one and six percent. Steroidal dietary supplements can be converted into testosterone or other androgenic compounds in the body. Steroidal over-the-counter dietary supplements such as androstenedione and tetrahydrogestrinone THG were previously available without prescription through health food stores, however, these supplements are now illegal after amendments to the Anabolic Steroid Control Act of Clinical research reports indicate that these agents are ineffective or lack evidence of performance-enhancing effects.
There is a wide array of serious side effects associated with abuse of anabolic steroids. Most side effects can be reversed if the drugs are stopped, but some, such as a deepened voice in women may persist. Data on long-term side effects primarily come from case reports and not from well-controlled, long-term epidemiological studies, which might be reliable. Users of anabolic steroids can become both physically and psychologically dependent upon the drugs, as evidenced by a drug-seeking behavior, continued use even with adverse effects, and physical withdrawal symptoms such as mood swings, fatigue, restlessness, loss of appetite, insomnia, reduced sex drive, and steroid cravings.
Severe withdrawal can lead to depression and possible suicide. Depressive symptoms can persist for up to one year after the user stops taking the steroid. Supportive treatments and medication interventions may be needed for severe anabolic addiction.
Medications that have been used for treating anabolic steroid withdrawal allow the natural hormonal system to restore. Other medications target specific withdrawal symptoms.
For example, antidepressants may be prescribed to treat depressive episodes and analgesics , such as acetaminophen or ibuprofen, may be used for headaches and muscle and joint pains. Some patients may also undergo behavioral therapies. Hoffman and Nicholas A.

Fast facts on anabolic steroids Here are some key points about anabolic steroids. The first reports of AAS use occurred following the world weightlifting championships, and the International Olympic Committee their use in Illegal use of AAS may involve doses 10 to times higher than the normal prescription dose. AAS are prescriptive controlled substances in the United States, but in many countries, they can be sold without a prescription for non-medicinal purposes.
All synthetic steroids combine the anabolic—or muscle-building—effects with the androgenic, or secondary male sexual characteristics. AAS use has been linked to a higher risk of heart attack or stroke.
Anabolic steroids can be taken orally, injected or applied directly to the skin. Most illegal users of anabolic steroids are men involved in bodybuilding, weightlifting and professional sports. The use of anabolic steroids can lead to many undesirable changes to the human body. Recent developments on anabolic steroids from MNT news Doping in sports: More teens are turning to steroids, study reveals Teens are risking their health in order to "bulk up" and "get toned" by using anabolic steroids and drinking protein shakes, according to a report conducted by researchers at the University of Minnesota and published in the journal Pediatrics.
High profile events like the Olympics look to inspire young people into sport. But, if they don't take appropriate measures, young athletes can end up in pain and on a path to poor health, due to avoidable sport injury. Research revealed on a BBC TV Horizon programme broadcast in February , suggests it is possible to improve some measures of fitness with just 3 minutes of exercise a week.
We take a look at a this idea. Some examples of the anabolic effects of these hormones are increased protein synthesis from amino acids , increased appetite, increased bone remodeling and growth, and stimulation of bone marrow , which increases the production of red blood cells. Through a number of mechanisms AAS stimulate the formation of muscle cells and hence cause an increase in the size of skeletal muscles , leading to increased strength.
The androgenic effects of AAS are numerous. Depending on the length of use, the side effects of the steroid can be irreversible. Processes affected include pubertal growth, sebaceous gland oil production, and sexuality especially in fetal development. Some examples of virilizing effects are growth of the clitoris in females and the penis in male children the adult penis size does not change due to steroids [ medical citation needed ] , increased vocal cord size, increased libido , suppression of natural sex hormones , and impaired production of sperm.
Men may develop an enlargement of breast tissue, known as gynecomastia, testicular atrophy, and a reduced sperm count. Compounds with a high ratio of androgenic to an anabolic effects are the drug of choice in androgen-replacement therapy e.
This disassociation is less marked in humans, where all AAS have significant androgenic effects. A commonly used protocol for determining the androgenic: The VP weight is an indicator of the androgenic effect, while the LA weight is an indicator of the anabolic effect. Two or more batches of rats are castrated and given no treatment and respectively some AAS of interest. Animal studies also found that fat mass was reduced, but most studies in humans failed to elucidate significant fat mass decrements.
The effects on lean body mass have been shown to be dose-dependent. Both muscle hypertrophy and the formation of new muscle fibers have been observed.
The hydration of lean mass remains unaffected by AAS use, although small increments of blood volume cannot be ruled out. The upper region of the body thorax, neck, shoulders, and upper arm seems to be more susceptible for AAS than other body regions because of predominance of ARs in the upper body.
After drug withdrawal, the effects fade away slowly, but may persist for more than 6—12 weeks after cessation of AAS use. Overall, the exercise where the most significant improvements were observed is the bench press. The measurement of the dissociation between anabolic and androgenic effects among AAS is based largely on a simple although arguably unsophisticated and outdated model involving rat tissue bioassays.
The intracellular metabolism theory explains how and why remarkable dissociation between anabolic and androgenic effects can occur despite the fact that these effects are mediated through the same signaling receptor, and of course why dissociation is invariably incomplete. An animal study found that two different kinds of androgen response elements could differentially respond to testosterone and DHT upon activation of the AR.
Changes in endogenous testosterone levels may also contribute to differences in myotrophic—androgenic ratio between testosterone and synthetic AAS. Testosterone can be metabolized by aromatase into estradiol , and many other AAS can be metabolized into their corresponding estrogenic metabolites as well.
The major effect of estrogenicity is gynecomastia woman-like breasts. AAS are androstane or estrane steroids. As well as others such as 1-dehydrogenation e. The most commonly employed human physiological specimen for detecting AAS usage is urine, although both blood and hair have been investigated for this purpose. The AAS, whether of endogenous or exogenous origin, are subject to extensive hepatic biotransformation by a variety of enzymatic pathways.
The primary urinary metabolites may be detectable for up to 30 days after the last use, depending on the specific agent, dose and route of administration. A number of the drugs have common metabolic pathways, and their excretion profiles may overlap those of the endogenous steroids, making interpretation of testing results a very significant challenge to the analytical chemist. Methods for detection of the substances or their excretion products in urine specimens usually involve gas chromatography—mass spectrometry or liquid chromatography-mass spectrometry.
The use of gonadal steroids pre-dates their identification and isolation. Medical use of testicle extract began in the late 19th century while its effects on strength were still being studied. In the s, it was already known that the testes contain a more powerful androgen than androstenone , and three groups of scientists, funded by competing pharmaceutical companies in the Netherlands, Germany, and Switzerland, raced to isolate it.
The chemical synthesis of testosterone was achieved in August that year, when Butenandt and G. Wettstein, announced a patent application in a paper "On the Artificial Preparation of the Testicular Hormone Testosterone Androstenoneol. Clinical trials on humans, involving either oral doses of methyltestosterone or injections of testosterone propionate , began as early as Kennedy was administered steroids both before and during his presidency. The development of muscle-building properties of testosterone was pursued in the s, in the Soviet Union and in Eastern Bloc countries such as East Germany, where steroid programs were used to enhance the performance of Olympic and other amateur weight lifters.
In response to the success of Russian weightlifters, the U. The new steroid was approved for use in the U. It was most commonly administered to burn victims and the elderly. The drug's off-label users were mostly bodybuilders and weight lifters. Although Ziegler prescribed only small doses to athletes, he soon discovered that those having abused Dianabol suffered from enlarged prostates and atrophied testes.
Three major ideas governed modifications of testosterone into a multitude of AAS: The legal status of AAS varies from country to country: Unlawful distribution or possession with intent to distribute AAS as a first offense is punished by up to ten years in prison. Those guilty of buying or selling AAS in Canada can be imprisoned for up to 18 months.
In Canada, researchers have concluded that steroid use among student athletes is extremely widespread. A study conducted in by the Canadian Centre for Drug-Free Sport found that nearly 83, Canadians between the ages of 11 and 18 use steroids. AAS are readily available without a prescription in some countries such as Mexico and Thailand. The history of the U. The same act also introduced more stringent controls with higher criminal penalties for offenses involving the illegal distribution of AAS and human growth hormone.
By the early s, after AAS were scheduled in the U. In the Controlled Substances Act, AAS are defined to be any drug or hormonal substance chemically and pharmacologically related to testosterone other than estrogens , progestins , and corticosteroids that promote muscle growth. The act was amended by the Anabolic Steroid Control Act of , which added prohormones to the list of controlled substances , with effect from January 20, In the United Kingdom, AAS are classified as class C drugs for their illegal abuse potential, which puts them in the same class as benzodiazepines.
Part 1 drugs are subject to full import and export controls with possession being an offence without an appropriate prescription. There is no restriction on the possession when it is part of a medicinal product. Part 2 drugs require a Home Office licence for importation and export unless the substance is in the form of a medicinal product and is for self-administration by a person. Many other countries have similar legislation prohibiting AAS in sports including Denmark,  France,  the Netherlands  and Sweden.
United States federal law enforcement officials have expressed concern about AAS use by police officers. It's not that we set out to target cops, but when we're in the middle of an active investigation into steroids, there have been quite a few cases that have led back to police officers," says Lawrence Payne, a spokesman for the United States Drug Enforcement Administration.
Following the murder-suicide of Chris Benoit in , the Oversight and Government Reform Committee investigated steroid usage in the wrestling industry.
The documents stated that 75 wrestlers—roughly 40 percent—had tested positive for drug use since , most commonly for steroids. AAS are frequently produced in pharmaceutical laboratories, but, in nations where stricter laws are present, they are also produced in small home-made underground laboratories, usually from raw substances imported from abroad. As with most significant smuggling operations, organized crime is involved.
In the late s, the worldwide trade in illicit AAS increased significantly, and authorities announced record captures on three continents. In , Finnish authorities announced a record seizure of A year later, the DEA seized In the first three months of , Australian customs reported a record seizures of AAS shipments.
Illegal AAS are sometimes sold at gyms and competitions, and through the mail, but may also be obtained through pharmacists, veterinarians, and physicians. AAS, alone and in combination with progestogens , have been studied as potential male hormonal contraceptives.
