FDA-Approved Peptides

The list of peptides with actual FDA approval is short — and full of compounds nobody in the research market is buying.

The reality check

FDA approval applies to specific drug products, not to molecules sold as research chemicals. "FDA-approved" is the most abused adjective in peptide marketing: the compound may have an approved drug form, while the vial you're looking at is an unapproved, unregulated grey-market copy of it.

Why this matters for sourcing

Approval ≠ what you're buying. A research vial labeled "semaglutide" has no FDA relationship whatsoever.
No approved peptide is sold as grey-market powder by its manufacturer. If a vendor claims to sell "pharma-grade FDA semaglutide," they're describing the molecule, not the product.
The regulatory gap is the point of the wiki: these compounds are studied in research contexts with in-vitro and animal models, which is exactly how this site treats them.

When a vendor says "FDA approved"

Ask: "Approved for what, and by whom, and does that approval apply to the exact product in this vial?" The answer will almost always be marketing. Run — don't walk — from vendors who can't answer it.
