Directory, not endorsement

This page is informational only. It includes mainstream, research, and gray-market sources, but it is not medical advice, a purchasing recommendation, or a claim that any vendor is safe, legal, or appropriate for human use. Verify COAs, testing, licensing, shipping rules, and local regulations.

GLP-1 suppliers

Vendors with GLP-1 naming or tracked metabolic peptides.

Large peptide catalogs and general research suppliers.

Specialty suppliers

Niche, quote-based, or harder-to-verify catalogs.

Sources with extra verification, legality, or product-identity risk.

Gray-market watchlist

These vendors have signals that need extra diligence: proprietary GLP naming, hidden or unclear pricing, login or age gates, bulk kit positioning, unusually low prices, or limited product identity transparency. Treat this as a research checklist, not a recommendation.
