About Bulk Peptides

Bulk Peptides is a US-based wholesale supplier of research-grade peptides established to serve institutional labs with reliable, highly characterized reference materials.

What is Bulk Peptides?

Bulk Peptides is a US-based wholesale supplier of research-grade peptides for institutional laboratories. Every compound clears a two-stage analytical process — HPLC purity and mass spectrometry identity confirmation — before catalog listing. We ship from domestic inventory with same-day dispatch, eliminating customs delays common with international peptide suppliers.

Where is Bulk Peptides located?

Bulk Peptides operates from Burlingame, CA 94010 (530 Beach Road). Our US-based fulfillment center ships domestically via FedEx and UPS with cold-chain packaging. Orders placed before 2 PM ET dispatch the same business day.

What quality standards do you follow?

We apply pharmaceutical-grade analytical standards: reverse-phase HPLC at 220 nm for purity, electrospray ionization mass spectrometry for identity. Our ≥99% purity threshold matches pharmaceutical reference standards. Every lot that fails either test is permanently rejected.

Who are your customers?

Our customers include university research laboratories, contract research organizations (CROs), biotech companies, and pharmaceutical companies that require well-characterized research peptides with documented analytical data. All products are for in vitro laboratory research use only.
