Frequently asked questions
Which sexual wellness peptides are FDA-approved?
Oxytocin, hCG, Triptorelin, Gonadorelin, hMG, PT-141 have an FDA-approved product, each for a specific labeled indication — not necessarily for sexual wellness in general.
How is this list ordered?
By regulatory status first (FDA-approved, previously approved, in clinical trials or approved abroad, preclinical), then by the number of PubMed-indexed clinical-trial papers. It ranks evidence, not sellers, and no company can pay to change the order.
Can I buy these online?
FDA-approved drugs require a prescription. Products sold as "research peptides" are labeled not for human use and are not FDA-approved; see each compound page for its status and our vendor directory for documented facts about sellers.
