Peptides A-Z

Quickly check what a peptide or peptide-like compound is, whether it has an FDA-approved use, and whether it is research-only, investigational, or banned in sport.

This is a safety and status index, not a recommendation list. Many entries are research-only or approved only for a narrow product-specific use. Research-only products are not approved for human use.

How to read status

FDA approved for specific use means there is an approved product or indication, not that vendor vials or off-label wellness use are approved. Investigational means clinical research may be underway but approval is not established. Research / not FDA approved means products sold for research use are not approved for human use.

Banned in sport flags compounds that competitive athletes should treat as prohibited or high-risk under anti-doping rules. Always verify the current rules for your sport and governing body.
