Strongest: the incretin class
GLP-1 receptor agonists and dual GLP-1/GIP agonists are the outlier in this whole field. They have large, long, randomised, placebo-controlled trials with hard outcomes — weight, glycaemic control, and in some cases cardiovascular events — and FDA-approved branded products exist. When someone says "peptides work", this is almost always the class doing the work in that sentence, and it is not representative of the rest.
Established but narrow
Several peptides are genuinely approved medicines for specific, narrow indications and are well evidenced for those uses only. Their approval does not travel to the broader wellness claims attached to them. A drug approved to change fat distribution in a defined clinical population is not therefore an anti-ageing agent, and a hormone approved for a diagnosed deficiency is not therefore a performance enhancer for people without one.
Emerging: growth hormone secretagogues
This group reliably raises growth hormone pulses and IGF-1 in humans. That much is not controversial. What remains thin is evidence that doing so, in people who are not deficient, produces the outcomes people buy them for — durable lean mass gain, better recovery, better sleep quality on objective measures — over meaningful periods. Effects on glucose regulation and fluid retention are real and are the reason monitoring is not optional.
Mechanism only: most of the rest
The repair, cognitive, tanning, immune-modulating and "mitochondrial" peptides that fill social media are, for the most part, supported by in-vitro work, animal models and small uncontrolled human series. The biology is often genuinely interesting. That is not the same as knowing what a course does to you over a year, and for several of them the compounding eligibility question is unresolved or already answered no.
We will not list those molecules as products on this site, because presenting them as a shelf you can choose from implies a lawful, evidenced route that does not exist for all of them. What your physician may prescribe is decided by your labs, your goals and what can lawfully be compounded — in that order.
Key points
- The incretin class is the evidence outlier and is not representative.
- An approval for a narrow indication does not travel to wellness claims.
- Most popular peptides rest on mechanism, not human outcomes.
