The nation's top health official is, in his own words, a "big fan" of peptides. On June 30, the scientists who work for him said the evidence is not there.
Health Secretary Robert F. Kennedy Jr. has promoted injectable "wellness" and "longevity" peptides as safe and effective self-care, largely from personal experience. On Joe Rogan's podcast he said, "I'm a big fan of peptides. I've used them myself and with really good effect on a couple of injuries." [4] In April, his department moved about a dozen peptides off the FDA's list of substances that pose significant safety risks and pushed to widen access to them through compounding pharmacies. [4][5]
What his own agency just found
On June 30, the FDA posted the staff review documents for a July 23-24 advisory meeting on seven of these peptides: BPC-157, KPV, TB-500, MOTs-C, DSIP, Semax, and Epitalon. [1] The agency's career reviewers reached one conclusion about all of them. There was, they wrote, insufficient evidence to support changing the restricted designation for any of the seven. [3] Not one cleared the bar. Zero for seven.

Why they were restricted to begin with
This is not the FDA suddenly inventing an objection. The agency placed peptides like BPC-157 and TB-500 in its "significant safety risks" category back in 2023, citing concrete concerns: the potential for the body to mount an immune reaction, impurities that come with compounded peptides, and a simple lack of human safety data. [2] TB-500 is banned by international sports authorities as a doping agent. [5] None of these seven has been through the kind of large, rigorous human trial that would tell us whether it heals injuries, builds muscle, or slows aging, the very things they are marketed to do. [3][4]
The difference between a testimonial and a trial
Here is the fair version, because it matters. Nobody is calling Kennedy a liar about his own body. It is entirely possible that a peptide injection coincided with an injury of his feeling better. That is exactly the problem with an anecdote: it can be completely sincere and still tell you nothing about whether a drug is safe and effective for millions of other people. One person's good week is not a clinical trial. The question in front of a health secretary is not whether something seemed to help him; it is whether the evidence supports opening the door to it for everyone. On June 30, the people he oversees answered that question, and the answer was no. [3]
The bottom line
A "big fan" is a fine thing to be about a band. It is not a standard of evidence for injectable drugs sold to the public. The FDA's own scientists looked at all seven peptides the Secretary has been promoting and found the case for none of them. When the safety review inside your own department contradicts your podcast endorsement, the honest move is to follow the review.
