US Research Peptide Supplier
Research Peptides For Sale
Research peptides for sale directly from the US-based lab that synthesizes them. ≥99% HPLC purity, batch-matched third-party COA from Verum Analytics, same-day US shipping.
About This Compound
Every research peptide for sale on BioInfinity is synthesized, QC-tested, and packaged at our Manhattan, New York facility. There is no reseller layer, no repackaged import, no anonymous overseas supplier. When you place an order, you are buying directly from the lab that made the peptide — with a batch-matched third-party COA proving it.
Every peptide on offer is manufactured by Fmoc SPPS, purified by preparative reverse-phase HPLC to ≥99%, identity-confirmed by ESI-MS (within ±0.5 Da of theoretical), and endotoxin-tested below 0.5 EU/mg by LAL assay. Every finished lot is additionally sent to Verum Analytics (Switzerland) for independent third-party verification. The resulting COA is public — browse the full library at /coa-library.
Categories on sale: healing / cytoprotective peptides (BPC-157, TB-500, GHK-Cu, KPV), GLP-family incretin agonists (Semaglutide, Tirzepatide, Retatrutide), mitochondrial and longevity peptides (MOTS-c, Epithalon, SS-31), immune / thymic peptides (Thymosin Alpha-1), neuropeptides (DSIP, Semax, Selank), and growth-hormone-axis peptides (CJC-1295, Ipamorelin). Every peptide has a dedicated buy page with full research context.
All orders ship same-day when placed by 3 PM ET Monday–Friday, with cold-chain packaging on transit routes that require it. Discreet plain unbranded outer boxes — only the address on the label.
