Because the liver is responsible for breaking down and removing excess chemicals from the body, anabolic steroids can cause severe liver damage. These substances have also been linked to high blood pressure, adult-onset diabetes mellitus, increased blood clotting factors, and decreased high-density lipoproteins (good cholesterol) in the blood, all of which increase the risk of cardiovascular disease. Performance-enhancing drugs (PEDs) like anabolic steroids, human growth hormones (HGH), and blood doping agents have been widely misused by athletes seeking competitive advantages. These substances, while sometimes medically prescribed, can have significant effects on an athlete’s likelihood of injury, recovery process, and long-term health. Furthermore, their use raises serious ethical questions about fairness and integrity in professional sports. Most of the PEDs that athletes and nonathlete weightlifters used before the 1990s were pharmacologic agents approved for medicinal or veterinary use.
PEDs, such as anabolic steroids, human growth hormone (HGH), and stimulants, can cause severe side effects that often outweigh the short-term performance benefits. An androgen is a sex hormone what are the effects of performance-enhancing drugs that promotes the development and maintenance of the male sex characteristics; testosterone is the principal secreted androgen in men. Androgens have both androgenic (masculinizing) effects (development of male secondary sex characteristics, including hair growth) and anabolic effects (increase in skeletal muscle mass and strength).
How Policies Have Changed Over Time
- The primary anabolic steroid hormone produced by your body is testosterone.
- Using drugs to improve performance in sport may lead to an athlete being banned and may also harm their health.
- PEDs can be taken orally or injected into body muscles, and some steroids are popularly applied via topical creams or gels.
- In general, the long-term effects of performance-enhancing drugs haven’t been studied enough.
A review of six research studies published in the journal Nutrients concluded that taking CLA supplements can have an effect on reducing body fat in those who also engage in a resistance training exercise program. It’s said to enhance and strengthen muscle as well as help slow the breakdown of muscle during exercise. This is when someone needs to take more steroids to achieve the same results. Androgenic effects contribute to male traits, including developing facial hair and a deeper voice. It appears safe for adults to take creatine at the doses recommended by manufacturers.
Status of asthma medication in sport
- While 7 substances were included in our literature search, only 5 substances were included in studies that met our screening criteria.
- NIDA is a biomedical research organization and does not provide personalized medical advice, treatment, counseling, or legal consultation.
- In higher doses, stimulants can also lead to more severe health effects, such as rapid heart rate and high blood pressure.
- A number of transdermal testosterone preparations have become available recently, but it is difficult to deliver large amounts of testosterone using the transdermal formulations.
- Athletes also use diuretics for post-recovery competitions like boxing and cycling to decrease the feeling of bloating or swelling.
With respect to the personality traits presented by chemsexers, it is difficult to distinguish if characteristic patterns of thoughts, feelings, and behaviors are derived from their specific personality or from polydrug use.

Peptide Hormones, Growth Factors, and Related Substances
Taking an excessive amount can put a strain on these important organs, which could potentially damage them. For example, creatine can cause weight gain, muscle cramping, and stomach cramping. Not surprisingly, hard numbers on rates of usage are difficult to come by, but anecdotal evidence isn’t lacking and anonymous surveys have provided some insight. Questionable use of medications and supplements have also been reported in the U.S. armed forces, fire and police departments, amateur athletics, and even high schools. This is because women typically don’t want to develop an extremely muscular physique or desire the masculinizing effects of steroids.
Growth hormone and growth factors
Given the potential financial rewards of athletic success, it’s no surprise that we’ve been witness to a seemingly endless procession of allegations and scandals. The complicity of medical professionals and shadowy labs is often involved, and a 2015 report heroin addiction from the International Cycling Union (UCI) found the sport’s own governing body bore significant responsibility. Patients who are deliberately using performance-enhancing drugs may not disclose use because of shame, legality concerns, or lack of trust. In fact, users of performance-enhancing drugs often are not candid with their physicians about their use of these drugs. While PEDs might offer short-term performance and recovery benefits, their long-term health consequences are severe. Steroid use has been linked to liver damage, cardiovascular diseases, and hormonal imbalances, including infertility in men and menstrual irregularities in women.
- In addition, AAS users often combine different forms of steroids, termed “stacking”, as a means of maximising muscle growth, which could account for the adverse cardiac effects experienced in some and not others 6.
- Oral preparations have a short half-life and are taken daily, whereas injectable androgens are typically used weekly or biweekly.
- Anabolic steroids can increase the risk of heart attacks by raising levels of “bad” cholesterol and decreasing “good” cholesterol.
- This study has been funded by the Italian Department of Antidrug Policies.
Cardiovascular System
Conversely, sports federations may test players for AAS but lack comparable data on concussive injuries. Insulin use also accelerates lipogenesis, inhibiting the release of free fatty acids (a muscle fuel); this is especially significant for endurance athletes. However, athletes can gain additional weight (adipose tissue as well), which could be detrimental to performance in many sports, especially those separated into weight classes. A test based on gas chromatography/combustion/isotope ratio mass spectrometry can detect the difference in 13C/12C ratios (CIRs) in endogenous and exogenous testosterone (360). The CIRs for androsterone, etiocholanolone, 5α- and 5β-androstanediol, and testosterone are documented. As an internal reference, tests use an endogenous steroid either upstream of the steroid of interest or from another steroid pathway, such as pregnanediol.
Anabolic Steroids
Last, as is the case with any SR, our search strategy and eligibility criteria may have unintentionally omitted relevant data. Primary outcomes collected were (1) body mass, (2) muscle strength, (3) performance, and (4) recovery. To provide an evidence-based review of 7 commonly used pharmacological interventions for performance enhancement in athletes. We also need to further investigate the interactive effects of PEDs with sports injuries and other high-risk behaviors as well as innovative approaches to enhance public awareness of the serious health consequences of PEDs.
- There are hundreds of nutritional supplements and more are being produced each year.
- The reason this drug has been popular among athletes is because it is difficult to detect.
- After the 2003 season, which was probably my most successful season on record, I had great results, had a big Tour de France.
As mentioned previously, this list is used by the IOC and other international cycling agencies such as the Union Cycliste Internationale to help control doping.93 In addition, rHuEPO use is prohibited by all major American sports organizations. When evaluating recovery metrics, there is no evidence to support that creatine has a recovery benefit. However, there were 2 studies showing that creatine may decrease muscle damage markers such as creatine kinase and lactate dehydrogenase.20,44 For rHuEPO, results showed that it provided no recovery benefit.
Side effects of substances used by athletes
The distribution of AAS use by nonathlete weightlifters shown in B differs substantially from that among athletes tested by WADA in A. Although testosterone, stanazolol, and nandrolone were the AASs most frequently found in WADA’s tests of athletes, testosterone, boldenone, trenbolone, and nandrolone were the AAS most frequently found in nonathlete weightlifters (19). These landmark discoveries have reinstated the view that multiple levels of the androgen receptor interactome contribute to tissue-specific actions of the androgen receptor ligands, and can be targeted to achieve the desired tissue specificity. Indeed, a number of SARMs have achieved relative differentiation of androgenic and anabolic activity, being preferentially more potent in the muscle than in the prostate (5–9, 12, 13). Several publications have described the mechanistic basis of tissue specificity (5–13).

However, steroids are thought to cause severe mood swings when used in large quantities and may cause heart disease in some people. In males there is also the threat of testicular atrophy (shrinking testicles), and in females, an increase in body and facial hair. The long-term health effects of performance-enhancing drugs on athletes are severe and wide-ranging.
