Three commonly confused categories with very different chemistry, legal status, and risk profiles. A plain-English breakdown.
Peptides, SARMs, and prohormones get lumped together in casual conversation, but chemically and legally they live in different worlds. Knowing which is which protects you from bad sourcing decisions.
Short chains of amino acids — biological building blocks. Most research peptides are sold for research, investigational, or licensed professional use only. They are not FDA-approved as drugs, but they are legal to manufacture and supply under clear research-use labeling.
Small molecules — not peptides — that bind androgen receptors with tissue selectivity. The FDA has issued explicit warnings against SARMs in over-the-counter products. Several are flagged on WADA's banned list for athletic competition.
Anabolic steroid precursors that convert to active hormones in the body. The U.S. Designer Anabolic Steroid Control Act of 2014 brought most prohormones under the Controlled Substances Act — they are not in the same legal lane as research peptides at all.
Research peptides operate in a clearly defined legal space when sourced and labeled correctly. SARMs and prohormones do not. Confusing the three is a common mistake — and an expensive one.
