Evidence over hype
Peptides for athletic performance and recovery, examined honestly.
Peptide Sport reads the primary research so you don't have to — separating what actually holds up from the locker-room marketing that doesn't. No hype, every claim sourced, and we say plainly who pays us.
If you are going to do it, do it legally
Our No. 1 sermorelin provider
The only lawful route to sermorelin or a GH-secretagogue is a prescription reviewed by a licensed clinician and filled by a compounding pharmacy. We ranked 9 telehealth providers that actually do that, on price transparency, clinical oversight and included support — not on any claim that these peptides improve performance, because no such benefit is proven.
Compare all 9 providersStill deciding whether any of it works? We graded the muscle-growth peptides one by one — every compound people stack for size, what the human trials actually found, and where each one sits on the WADA list.
Tested sport · prohibited at all times
Sermorelin and the other GHRH analogs are WADA class S2 — banned in and out of competition, and a prescription does not make them permitted. Check any compound in our prohibited-status checker before you spend anything.
