Performance Enhancers: The Safe and the Deadly

Throughout the study, the rats had limited social interactions on a daily basis. After 1 week, rats received nandrolone or placebo, and their behavior was observed over 2 months. Dominant AAS-treated rats spent more time on highly aggressive behaviors than the dominant placebo-treated rats. In addition, the probability for highly aggressive behaviors was maintained for the AAS-treated rats throughout the study, whereas it was decreased for the placebo-treated rats. These observations are similar to the relatively long-term behavioral changes we see in humans after AAS use. Patronage of wellness and antiaging clinics may also put recreational athletes at risk of inadvertent positive doping test results because treatments prescribed at these centers often include hormone replacement.

Mental Side Effects

Because AASs, hGH, insulin, and erythropoietins are the most frequently used PEDs, we address the medical consequences of their use in detail below. Although AAS use is widespread in Western countries, the United States appears to have the largest absolute number of AAS users. This is not surprising because the United States is the most populous country with substantial AAS use, and likely the first country in which AAS use began to spread from elite athletics to the general population (18). In 2005, androstenedione was classified as a schedule III controlled substance. Unfortunately, the Dietary Supplement Health and Education Act of 1994 allows many steroid precursors to be sold over the counter with minimal regulation. Agents such as right-shifting reagent 13 (RSR13) can modify hemoglobin (Hb) such that it shifts the O2 dissociation curve so that O2 is more easily released in the peripheral muscle.

Public financing of sports venues: 7 reporting tips from our webinar

  • USA Weightlifting also established a similar Lift Clean Program to fight doping at all levels of weightlifting competition, from national to local events, through anti-doping education and testing.
  • Although other players said they didn’t see widespread steroids use in the game, Canseco reported that he did.
  • We are supported by generous grants from the Carnegie Corporation of New York, the Robert Wood Johnson Foundation, The National Institute for Health Care Management (NIHCM) Foundation and individual contributors.
  • For example, the masking agent probenecid stops the excretion of steroids for a few hours, decreasing the concentration of steroids in the urine.
  • This growing body of literature suggests that despite the singularity of the androgen receptor protein, tissue selectivity of ligand action can be achieved.
  • Perhaps the most important message for practitioners is to be alert to the potential for PED use, to confidentially enquire about the use of drugs while being aware that denial may not discount the possibility.

Users may supplement their program of injections and pills with topical gels to provide a constant low-level testosterone supply. Recent studies increasingly suggest that the use of AASs and other PEDs often occurs in conjunction with use of multiple classical drugs of abuse (77, 78). PED users are increasingly encountered in needle-exchange programs, where they may sometimes represent most of the clientele (79, 80). Over the past 25 years, there has been an explosion in youth sports participation, resulting in a dramatic increase in the total number of athletes under age 18 years. It is estimated that more than 30 million children and adolescents are participating in organized sports today.


USA Weightlifting also established a similar Lift Clean Program to fight doping at all levels of weightlifting competition, from national to local events, through anti-doping education and testing. Under a congressional mandate, USADA is responsible for protecting clean sport in the United States by educating, testing, and adjudicating cases for a wide range of competitors, including the country’s most elite athletes. More specifically, USADA is responsible for managing the anti-doping initiatives that apply to Olympic, Paralympic, Pan American, and Parapan American athletes. For example, anabolic and other steroids that affect a person’s hormones can cause long-term health problems — or even death.

NIDA-Funded Prevention Research Helps Reduce Steroid Misuse

  • In 2010, the survey revealed the annual male adolescent prevalence rates for steroid use of 0.7% for 8th-graders, 1.3% for 10th-graders, and 2.5% for 12th-graders.
  • These flexible programs provide care to those who don’t want to or can’t be removed from their regular lives during recovery.
  • Rats and mice display conditioned place preference to testosterone (260,–262), and male hamsters will self-administer testosterone to the point of death (263).

Each year, the survey investigates substance abuse and use in ∼50,000 8th-, 10th-, and 12th-grade students. In 2010, the survey revealed the annual male adolescent prevalence rates for steroid use of 0.7% for 8th-graders, 1.3% for 10th-graders, and 2.5% for 12th-graders. The annual female adolescent prevalence is 0.3% in 8th-graders, 0.5% in 10th-graders, and 0.3% for 12th-graders.

What are the risks of anabolic steroid use in teens?

This metabolite is long-lived and can be detected 28 days after administration! To detect stanozolol from this metabolite, a complex combination of methods involving electrospray ionization (ESI) and liquid chromatography mass spectrometry (LC-MS) was more recently developed. Simply put, these techniques create ions which can be separated and identified by their mass to characterize and identify the metabolites present. Some of the adverse effects performance enhancing drugs seen in patients who use AASs may include infertility, gynecomastia, sexual dysfunction, hair loss, acne, muscular appearance, and testicular atrophy. Some indicators that might suggest AAS use are increased hemoglobin and hematocrit; suppressed LH, FSH, and testosterone levels; low high-density lipoprotein cholesterol, and low sperm density. Mass spectrometry-based tests (available in many commercial laboratories) can detect AASs in urine.

Performance Enhancing Drugs

While none of the players were charged with using PEDs, the BALCO case was one factor in spurring baseball to toughen its stance and institute a drug-testing program. The home run heroics of the 1998 and 2001 seasons were called into question as McGwire, Sosa and Bonds were among a group of major leaguers linked to the use of PEDs in the following years. Midway through the 1997 season, McGwire was traded to the St. Louis Cardinals. The move set the stage for a memorable season when he and Sammy Sosa of the Chicago Cubs battled for the National League home run title, during a year in which 13 different major leaguers hit at least 40 home runs. Depression has also been linked to steroid use, and athletes who use performance-enhancing steroids are more likely to attempt suicide than athletes who do not use them. Steroid users may become overly aggressive or combative, a condition commonly referred to as “’roid rage.” Uncontrolled aggression causes some steroid users to become confrontational with friends and family; sometimes, they end up in trouble with the law.

Consequences and Sports Governance

  • Finally, some nonathlete weightlifters use clenbuterol, a β-adrenergic agonist that is thought to possess possible anabolic properties.
  • In therapy, people work on adjusting to a life without steroids, learning life skills that help them prevent relapse, and identifying their triggers.
  • The burst-forming units (erythroid [BFU-E]), proerthyroblasts, and basophilic erythroblasts also express erythropoietin receptors.

Athletes and nonathletes often use it after heavy workouts to enhance recovery. The ingestion of glucose is vital to this type of doping, given the glucose-lowering action of insulin, especially in those with normal tissue insulin sensitivity. The rationale of injecting insulin as a PED relates to its mediation of increases in the transport of glucose and amino acids into skeletal muscle and its effects on muscle fibers. By infusing insulin along with stable isotopes of glucose and amino acids into human muscle (quadriceps), Biolo and coworkers (386) were able to demonstrate an approximately 70% increase in the fractional synthetic rate of muscle protein. They also reported a decrease in the concentrations of the essential amino acids, implicating incorporation into the muscle fiber.

Performance Enhancing Drugs

Although the cardiovascular side effects of some of the drug classes can be anticipated, many athletes will use multiple agents and the effects of drug combinations is almost nonexistent. It is also critical to note that of potentially greater risk to athletes’ health are the many agents that are likely to be in use currently that are unknown to authorities. The known side effects of some of the more commonly abused agents are presented below but, given the limited evidence base, these should be considered a best guess.
