Evidence-based research
Every claim on Peptide Sport is tied to primary research or official labeling. Each piece below shows how many primary sources it cites, and whether it grades the compounds it covers on an explicit evidence tier rather than leaving the verdict buried in prose.

If you decide to run a legal program
Sermorelin and the GH-secretagogues are WADA class S2 — prohibited at all times, in and out of competition, and a prescription does not make them permitted. If you are tested, check the compound in our prohibited-status checker before anything else. If you are not, we ranked 9 telehealth providers on price transparency, clinical oversight and included support.
