LabFirst Peptides
LabFirst Peptides is a research peptide supplier in Santa Ana, California. Every size is listed with its price and cost per milligram, and volume tiers are fixed: 10% off 10 to 19 vials of one SKU, 15% off 20. Its release specification is public: identity by LC-MS, purity of at least 99% by RP-HPLC, and net content of at least 85% of the label. Lots are tested by Kovera Labs, an independent laboratory, and each published certificate links to Kovera's own verification page with the lot number printed on the vial. The site reports how many of its sizes carry a lot certificate and leaves the rest blank until their lots are tested. If an independent test of a vial does not match its lot certificate, LabFirst refunds that lot in full with no time limit. The catalog covers Retatrutide, Tirzepatide, Semaglutide, BPC-157, TB-500, GHK-Cu, NAD+, Tesamorelin, MOTS-c, SS-31, Semax, Selank and blends. Orders ship from Santa Ana by USPS with tracking, free over $150. Products are for laboratory research use only, not for human or animal use.
