Key Takeaways
- According to the 2022 World Anti-Doping Agency Testing Figures Report, 1.4% of all urine samples (830 out of 59,053) analyzed from international-level athletes tested positive for anabolic androgenic steroids (AAS)
- A 2021 study in the British Journal of Sports Medicine found that 44% of male professional rugby players in New Zealand admitted to past or current use of AAS during their careers
- The 2019 Global Drug Survey reported that 4.6% of gym-goers worldwide (n=18,000 respondents) had used anabolic steroids in the past year
- Long-term AAS use increases risk of myocardial infarction by 4.6-fold in men under 40, per a 2020 Circulation study (OR=4.6, 95% CI 2.1-10.1)
- NIH data shows anabolic steroids elevate LDL cholesterol by 20-50% and reduce HDL by 30-60% within 12 weeks of use
- A 2022 JAMA Internal Medicine meta-analysis linked AAS to 2.5x higher cardiomyopathy risk (RR=2.54, n=15 studies)
- High-dose testosterone increases muscle protein synthesis by 50-100% within 3-6 weeks, per 2019 Journal of Physiology study (n=48 resistance-trained men)
- EPO administration raises VO2 max by 10-15% and endurance performance by 12% in cyclists, 1997 NEJM trial (n=68)
- A 2021 Sports Medicine review: Anavar (oxandrolone) boosts sprint power output by 7-9% in short-term use for sprinters
- WADA's Athlete Biological Passport detected 45% more micro-dosing cases in 2022 vs 2020 (180 vs 124)
- LC-MS/MS urine analysis sensitivity for boldenone metabolites reaches 0.1 ng/mL, detecting use up to 18 months post, 2021 Analytical Chemistry
- Dried blood spot testing for hGH isoforms achieves 95% specificity at 20 ng/mL cutoff, 2023 WADA validation
- WADA imposed 2,368 anti-doping rule violations (ADRV) in 2022, up 12% from 2021
- IOC Beijing 2022 Olympics: 52 ADRV out of 2,976 tests (1.75% positivity)
