Anabolic steroid use is reported by about 3.3 million people in the US aged 12 and up, and the training outcomes can look just as stark in controlled studies. In a single 10 week protocol, testosterone enanthate boosted squat strength by 13% and bench press by 9%, while other compounds have been linked to rapid changes in muscle protein synthesis, hemoglobin, and recovery. But the same dataset that tracks performance gains also runs hard into cardiovascular, liver, and endocrine risks, which is why the stats are so hard to interpret without seeing the full picture.
Key Takeaways
- Anabolic steroids increase lean body mass by 5-10% over 10 weeks in resistance-trained men per 1996 randomized trial of 43 subjects
- Testosterone enanthate at 600mg/week boosts squat strength by 13% and bench press by 9% in 10-week study of 43 athletes
- Nandrolone decanoate increases muscle protein synthesis by 200-300% acutely in trained males per 2001 study
- Anabolic steroid use increases risk of cardiomyopathy by 2.5-fold in users per 2017 meta-analysis of 24 studies involving 97 cases
- Long-term anabolic steroid use is associated with a 4.6 times higher odds of myocardial infarction in men under 45 per 2015 case-control study
- AAS users have 3.9 times increased risk of tendon rupture compared to non-users per 2014 review of 37 studies
- Anabolic steroids are classified as Schedule III controlled substances under the US Controlled Substances Act of 1990
- WADA prohibits AAS in and out of competition under S1 Anabolic Agents category since 2004
- Possession of anabolic steroids without prescription is punishable by up to 1 year prison and $1000 fine in US per 21 USC 844
- Anabolic steroids are FDA-approved for treating hypogonadism in men with serum testosterone <300 ng/dL
- Oxandrolone is prescribed for burn patients, promoting 2-3x faster wound healing and muscle preservation per RCTs
- Nandrolone decanoate treats HIV-associated wasting, increasing weight by 2-4kg in 12 weeks per 1999 study
- Approximately 3.3 million people aged 12 or older in the US reported past-year anabolic steroid use in 2019 according to the National Survey on Drug Use and Health
- In a 2020 survey, 4.5% of US high school students reported lifetime anabolic steroid use, with males at 6.8% and females at 2.2%
- Globally, an estimated 3.3% of the male population aged 15-64 has used anabolic steroids at least once according to a 2014 meta-analysis
AAS can boost strength and lean mass within weeks, but they raise serious health risks.
