GLP-1 Research Lab
GLP-1 Research Lab (Peptide Research Labs Inc) is a US-based research-peptide supplier focused on the GLP-1 metabolic class (Semaglutide, Tirzepatide, Retatrutide, Cagrilintide) alongside recovery, GH-secretagogue, and longevity compounds. It publishes a third-party Certificate of Analysis from Prime Analytical Laboratories, a named US lab in Concord, CA — the posted Tirzepatide report verifies 100.0% purity by HPLC with net peptide content and a clean single peak.
The testing is real and third-party, which anchors the COA factor; what holds that factor mid for now is breadth — one certificate is published rather than a per-batch library on every product page, and the panel is purity-only. The brand is new, so there isn't a public review footprint to lean on yet, but it's run by an established operator and its operations are a genuine strength: card and crypto payment, in-stock inventory, a 30% affiliate program, and professional cold-chain fulfillment. Expect the COA coverage — and the score — to rise as its new lab partnership produces per-batch COAs.
