Peptides, SARMs, and “No Free Lunch”: Why You Must Know the Side Effects

In this Iron Radio episode, hosts Coach Phil Stevens, Dr. Mike T. Nelson, and Dr. Lonnie Lowery discuss growing use of peptides, SARMs, and other drugs in gyms and the general public, emphasizing that many people take substances without understanding risks, side effects, dosing tradeoffs, or product quality. They compare older, better-studied compounds to newer agents with limited or no human data, and highlight dangers of injection practices, sterility issues, and mislabeled products. Mike shares a Journal of Nutrition study (Sato et al., industry-funded by Morinaga) on an oral whey hydrolysate tetrapeptide (leucine-aspartate-glutamine-tryptophan) in 181 overweight adults, reporting about a one-inch waist reduction and improved mood over 8–12 weeks. The conversation broadens to impatience, lifestyle disease, and the value of slow, informed, long-term progress in training, dieting, and health.
