US Research Peptide Supplier
Buy Peptides Online
Order research peptides online from BioInfinity — a US-based supplier shipping ≥99% HPLC purity peptides same-day from Manhattan, with a batch-matched third-party COA in every box.
About This Compound
Buying peptides online can feel like a minefield — endless offshore suppliers, no COAs, no visible physical address, no clear return policy. BioInfinity is the opposite: a fully-transparent US-based research peptide supplier with a registered New York business, published Manhattan facility address, and public batch-matched COA for every peptide we ship.
Ordering online with us takes ~90 seconds. Add products to your cart, complete our compliance check (research-use acknowledgement + jurisdiction confirmation), enter shipping and payment, and you'll have a USPS or UPS tracking number in your inbox within an hour of order confirmation on any business day.
Every peptide is synthesized by Fmoc SPPS, purified by preparative reverse-phase HPLC to ≥99%, identity-confirmed by ESI-MS, and endotoxin-tested below 0.5 EU/mg by LAL. Every batch is independently verified by Verum Analytics (Switzerland) — the resulting COA is publicly browsable in /coa-library and printed inside your shipment.
Payment methods accepted online: credit/debit card, Zelle, Venmo, Cash App, USDC stablecoin, and wire transfer for institutional orders. Shipping options: USPS Priority (2-3 business days) or UPS Ground (3-5 days), cold-chain when the transit route requires.
