US Research Peptide Supplier
Buy Research Peptides in the USA
BioInfinity is a US-based research peptide supplier shipping ≥99% HPLC purity peptides same-day from Manhattan. Every vial ships with a batch-matched third-party Certificate of Analysis. Research use only.
About This Compound
BioInfinity supplies research-grade peptides to independent researchers, academic laboratories, contract research organisations, and educational institutions across the United States. Every peptide we ship is manufactured by solid-phase peptide synthesis (SPPS), purified to ≥99% by preparative reverse-phase HPLC, identity-confirmed by mass spectrometry, and endotoxin-tested by LAL assay.
Our catalog spans the most extensively cited research-peptide families in the current literature — the healing / cytoprotective peptides (BPC-157, TB-500, GHK-Cu, KPV), the GLP-family incretin agonists (Semaglutide, Tirzepatide, Retatrutide), the mitochondrial & longevity peptides (MOTS-c, SS-31, Epithalon), the immune & thymic peptides (Thymosin Alpha-1), the neuropeptide family (DSIP, Semax, Selank), and the growth-hormone-axis peptides (CJC-1295, Ipamorelin).
Every batch is sent to Verum Analytics (Switzerland) for independent third-party verification. The resulting Certificate of Analysis is publicly browsable on our /coa-library — no login, no email gate. Every vial carries a batch verification code that resolves to the exact HPLC / MS / endotoxin data for that lot.
All orders ship same-day from our Manhattan facility when placed by 3 PM ET Monday–Friday, with USPS Priority (2-3 days) or UPS Ground (3-5 days) options. Cold-chain gel-pack packaging is included on transit routes that require it. Discreet plain unbranded outer boxes; the label carries only the address and standard postal markings.
