Welcome to Pep in Her Step. Each week, we cut through the noise on peptides and GLP-1 research to bring you clear, evidence-based insights for real life. No hype, no judgment, just credible information to help you make confident decisions about your health.

We exist because peptides went mainstream (thank Ozempic), the internet responded with ten thousand confident opinions, and almost none of the protocols were actually tailored to, or tested in, women's bodies. That is the gap this newsletter lives in. We read the studies, we note who was actually in the cohorts, and we tell you what holds up.

Let's go. ☕

The Big One

The FDA peptide vote, decoded

Last Thursday and Friday, an FDA advisory committee reviewed seven peptides that some pharmacies have been quietly compounding for years, and voted, narrowly, to recommend six of them for a list that would let licensed compounding pharmacies prepare them by prescription. DSIP (research-only, not FDA-approved for any human use) was the one voted down. BPC-157, KPV, TB-500, MOTS-c, Semax, and Epitalon are also research-only and not FDA-approved. Semaglutide (Wegovy, Ozempic, FDA-approved) and tirzepatide (Zepbound, Mounjaro, FDA-approved) were not part of this vote.

If your feed sounds like the peptide era just became official, here is what the vote does and doesn't mean.

It's a recommendation, not a rule

Advisory committees advise. The FDA is not bound by the vote and has not acted on it. As of this issue, nothing has changed at any pharmacy counter.

The FDA's own scientists said no

Agency staff recommended against all seven compounds, citing gaps in safety and effectiveness data, and the committee overruled them. That kind of public split between an agency and its own advisory panel is rare, which is part of why this made national front pages.

"Compounded" is not "approved"

Even if the FDA adopts the recommendation, these peptides would be compounded by prescription, not approved as drugs. Compounded products skip the clinical trials, the approved labeling, and the manufacturing oversight that approved drugs go through. And none of this touches the vials sold online as "research use only," which remain exactly as unregulated as they were last month.

Why it matters for women

Women are the core telehealth customer, and telehealth companies are already positioning to sell these compounds the moment the door opens. The gap between "a panel voted" and "this is safe and proven for you" is where the marketing will live for the next year. Our job is to keep pointing at that gap.

The Female Data Gap

The compound your feed is most confident about is the one with the least human data of anything we will ever cover.

What the evidence says

Adults don't grow. The growth plates in long bones close in the late teens, and no medication reopens them. What does change with significant weight loss is posture: less abdominal weight lets the spine straighten, and people genuinely stand taller. Height also varies by up to a couple of centimeters across a single day as spinal discs compress and rehydrate. Measure yourself in the morning after weight loss, compare it to an evening measurement from before, and you have the appearance of growth without the biology to back it up.

Ask a Clinician

There are three questions a legitimate clinic can answer without hesitation, and the quality of the answers tells you a lot.

First: which of the compounds in the program are FDA-approved, which are compounded by a licensed pharmacy with a valid prescription, and which are neither? A program that can't give a clear, direct answer to that question is worth pausing on.

Second: who is the supervising prescriber, and will you actually have a clinical encounter with that person? A valid prescription requires a real prescriber-patient relationship. If the answer is vague, that is itself useful information.

Third: where does the product come from? Compounded medications should originate from a state-licensed or 503B-registered pharmacy, not an overseas supplier or a vial labeled "research use only." Any clinic worth working with will welcome that sourcing question, not sidestep it.
