Before he attended medical school, Thomas O’Connor, MD, had a not-very-well-kept secret: As a competitive powerlifter, he had used steroids to build strength.
Now an internist and clinical instructor of medicine at the University of Connecticut, Farmington, Dr. O’Connor’s practice focuses on the needs of men taking testosterone and other anabolic steroids – a group he feels is poorly understood and largely neglected by conventional medical care, perceptions borne out by a 2020 study of steroid users he helped conduct.
“They felt discriminated against, they did not feel comfortable working with their physicians, and they felt that the doctors did not know what they were doing,” Dr. O’Connor said in an interview. His patients often express anger and frustration with doctors they had seen previously.
Patients turning to home tests
Clients can order a panel of labs designed to screen for health conditions commonly associated with use of AAS, such as dyslipidemia, renal and hepatic dysfunction, polycythemia, thrombosis, and insulin resistance. The panels also include tests for levels of different hormones.
Sales of direct-to-consumer tests topped $3.6 billion in the United States in 2022 and are predicted to grow. Some of that spending is coming from people, mostly men, using illegally obtained steroids to build muscle. Although published data on the size of the bodybuilder market are unavailable, the Internet is a ready source of relatively inexpensive tests aimed at helping individuals monitor their health.
While clinicians may have their doubts about allowing patients to pick and choose tests and interpret their results, proponents claim they empower consumers to take control of their health – and save themselves money in the process.
But a test panel designed to help the user monitor the effects of banned substances is a bit unnerving to many clinicians, including Dr. O’Connor.
“People using anabolic steroids should be aware of the health risks associated with such use and that laboratory analysis is an important step toward improving health outcomes,” he said, “I’m all about open education, but not self-diagnosis and treatment.”
Testosterone and other AAS such as nandrolone, trenbolone, and boldenone are Schedule III controlled substances that have been banned by numerous athletic governing bodies. Yet recreational users can easily obtain them from online international pharmacies without a prescription. Should they be monitoring themselves for side effects?
A basic problem is that few primary care clinicians routinely ask their patients about the use of AAS or feel competent to manage the complications or withdrawal symptoms associated with the agents. And they may have no idea what the average AAS user looks like.
The American College of Sports Medicine updated its statement on the use of AAS in 2021. The statement warned of a growing new segment of users – up to 70% of people who take the drugs do so recreationally in pursuit of a more muscular appearance, rather than competitive athletes seeking enhanced performance.
The ACSM highlighted the syndrome of muscle dysmorphia, also known as “megarexia” or “bigorexia” (think of it as “reverse anorexia”), as a major risk factor for illicit use of AAS.
Stuart Phillips, PhD, professor and director of the department of kinesiology at McMaster University, Hamilton, Ont., coauthored the ACSM guidelines.
“The prince in Snow White circa 1950s was a guy with nice hair,” said Dr. Phillips, pointing to a change in cultural expectations for the male body. “But then fast forward to the prince or hero in any other Disney movie recently – and the guy is jacked.”
Since the last guidelines were published in 1987, Dr. Phillips has seen some cultural shifts. Testosterone has gone from a banned substance no one talked about to a mainstream medical therapy for men with low androgen levels, as any television viewer of primetime sports can attest. “But the other thing that’s changed,” he added, “is that we’ve seen the proliferation of illicit anabolic steroid use solely for the purpose of aesthetics.”
As an adolescent medicine physician who specializes in eating disorders, Jason Nagata, MD, MSc, sees many young men in his practice who engage in different behaviors to increase their muscle mass – from exercising, consuming high protein diets or taking protein supplements, even injecting AAS.
“A third of teenage boys across the U.S. report they’re trying to gain weight to bulk up and gain muscle,” said Dr. Nagata, an associate professor of pediatrics at the University of California, San Francisco.
In a 2020 study published in JAMA Pediatrics, Dr. Nagata and colleagues found that use of legal performance-enhancing substances in young men aged 18-26 years was associated with a higher odds of using AAS 7 years later (adjusted odds ratio, 3.18; 95% confidence interval, 1.90-5.32). “Some of the legal performance-enhancing substances like the protein powders or creatine may serve as a gateway to use of AAS,” Dr. Nagata said.
Another important factor is exposure to AAS use on social media, where muscular influencers gain huge followings. Dr. Nagata said most of the research on eating disorders and social media has examined the role of media on weight loss in girls.
“Although there’s less research on the social media impact on boys and men, a few studies have shown links between more Instagram use and muscle dissatisfaction, as well as thinking about using steroids,” he said.
The number of people using AAS is not trivial. In a longitudinal study (led by Nagata) of young U.S. adults surveyed multiple times between 1994 and 2002, a total of 2.7% of 18- to 26-year-old men and 0.4% of women reported using AAS. In a more recent cohort of adolescents in Minnesota aged 14-22 years followed between 2010 and 2018, a total of 2.2% of males and 1% of females initiated AAS use.
The Endocrine Society has estimated that between 2.9 and 4 million Americans have used an AAS at some point in their lives. Given that use is illegal without a prescription, a limitation of any survey is that participants may not be willing to disclose their AAS habit, leading to an underestimate of the actual number.
Nor are the complications of AAS use negligible. The drugs can have wide-ranging effects on the body, potentially affecting the brain, heart, liver, kidneys, musculoskeletal system, immune system, and reproductive systems. And individuals might unknowingly expose themselves to AAS: A recent literature review found that over a quarter of dietary supplements tested were found to contain undeclared substances that are on the World Anti-Doping Agency’s list of banned agents.
