The short version.
A subset of male fitness influencers normalize anabolic steroid use and SARMs — selective androgen receptor modulators, sold as 'research chemicals' to skirt FDA rules. Both can cause cardiac and hepatic damage; SARMs in particular are unregulated, often contaminated, and bought from anonymous online suppliers. Teen and young-adult use has risen sharply since 2020.
The platforms and contexts.
Instagram and YouTube fitness creators; private Discord servers for sourcing; Telegram channels for the actual purchases. SARMs are sold openly on dozens of online 'research chemicals' sites.
The timeline.
Anabolic steroids in U.S. teen sports are an old problem (FDA studies date to the 1980s). SARMs became mainstream in teen fitness content around 2018 and accelerated through the pandemic.
The core facts a parent needs.
- SARMs sold as 'research chemicals' are largely unregulated; FDA testing has found 25–50% of products are mislabeled or contaminated with actual anabolic steroids.
- Even short cycles in adolescents (whose growth plates may not be closed) can cause permanent height loss, cardiac changes, and hormonal disruption.
- Insurance and pediatricians treat anabolic use as a medical issue, not a moral one — disclosure to a doctor doesn't trigger reporting.
What's actually at stake.
- Cardiac: left ventricular hypertrophy, arrhythmia, sudden cardiac death.
- Hepatic: liver inflammation and failure, particularly with oral compounds.
- Hormonal: testicular atrophy, infertility, gynecomastia, sometimes permanent.
Concrete next steps.
- Have the conversation with the names — Ostarine, RAD-140, LGD-4033, anavar, dianabol, trenbolone. A teen knows these; a parent who knows them gets taken seriously.
- Pediatrician or adolescent-medicine doctor for any teen using or considering. The disclosure is medical, not punitive.
- Counter-content: legitimate fitness creators (Jeff Nippard, Mike Israetel) discuss natural limits openly. Compete with their voice, not against the lifestyle.
