A marketplace built on verification, not ads.
Likwid is the directory and verification layer for research-grade peptides. We don't manufacture, sell, or take a cut — we standardize the data so labs can compare distributors honestly.
Discovery layer
Search the catalog by category, mechanism, or research focus — every listing standardized to the same data shape.
Verification layer
Every vendor passes HPLC + COA review before they're listed. The badge means documented testing, not marketing.
Comparison layer
Stack vendors side-by-side on purity, price, testing method, and lead time — pulled from real distributor data.
Direct connection
Request info, COAs, or quotes straight from a vendor. Likwid never takes a cut — orders ship from the lab.
