US Research Peptide Supplier
Buy Research Peptides
Purchase research peptides directly from BioInfinity — US-based synthesis, ≥99% HPLC purity, batch-matched third-party COA from Verum Analytics Switzerland, same-day US shipping.
About This Compound
When you buy research peptides from BioInfinity, you are ordering directly from the US-based facility that synthesizes, purifies, packages, and ships them. There is no wholesale-reseller layer, no repackaged import, no unbranded "grey market" supply. Every step of the process — from Fmoc SPPS synthesis to final lyophilization and vial-fill — happens at our Manhattan, New York laboratory.
Purity is verified to ≥99% by reverse-phase HPLC, identity is confirmed by ESI-MS, and endotoxin is 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 Certificate of Analysis is publicly browsable in our /coa-library with no login required.
Our research-peptide catalog spans the major tool-compound families in the current preclinical and in-vitro literature — healing peptides (BPC-157, TB-500, GHK-Cu, KPV), incretin family (Semaglutide, Tirzepatide, Retatrutide), mitochondrial and longevity peptides (MOTS-c, Epithalon, SS-31), immune peptides (Thymosin Alpha-1), and neuropeptides (DSIP, Semax, Selank).
Orders placed by 3 PM ET Monday–Friday ship same-day from Manhattan. Cold-chain gel-pack packaging is included on any transit route that requires it. Discreet plain unbranded outer boxes — the label carries only the address and standard postal markings.

Frequently Asked Questions
What is the best way to buy research peptides in the USA?▾
Buy directly from a US-based supplier that synthesizes in-house and provides an independent third-party COA with every batch. BioInfinity synthesizes at our Manhattan facility, verifies every batch through Verum Analytics (Switzerland), and publishes every COA publicly in /coa-library.
How do I know a research peptide supplier is legitimate?▾
Three signals: (1) US-registered business with a real physical address, (2) batch-matched third-party COA (not just an internal in-house HPLC), and (3) publicly browsable verification codes on every vial. BioInfinity meets all three.
Do I need a license to buy research peptides in the USA?▾
No — research chemicals sold for in-vitro laboratory use are legal to purchase in the US when properly labeled as "for research use only" and not intended for human consumption. That is how BioInfinity supplies them.
How fast do research peptide orders ship?▾
Orders in by 3 PM ET Monday–Friday ship same-day from Manhattan. USPS Priority (2-3 days) or UPS Ground (3-5 days). Cold-chain when the transit route requires it.
What payment methods work for research peptide orders?▾
Credit/debit card, Zelle, Venmo, Cash App, USDC stablecoin, wire transfer for institutional orders. Zelle typically clears fastest.
Do you offer bulk pricing on research peptides?▾
Yes — Professional accounts qualify for tiered volume discounts. Register a Professional account or contact [email protected] with your institution and PO details.
