FDA to weigh easing limits on unproven peptides favored by RFK Jr. and other MAHA figures

The Food and Drug Administration will hold a meeting this summer to consider easing restrictions on more than a half dozen peptide injections, a group of unapproved therapies that have become popular among wellness influencers, fitness gurus and celebrities.

The meeting announcement Wednesday follows repeated pledges by Health Secretary Robert F. Kennedy Jr. to loosen regulations on peptides, which are often pitched as a quick way to build muscle, heal injuries or appear younger. There’s little research behind those claims and most peptides have not been reviewed for safety by the FDA.

Kennedy has discussed using peptides for his own injuries. And some major supporters of his Make America Healthy Again movement are big proponents of them, including Gary Brecka, a self-described “longevity expert” who sells various peptide formulas through his website.
