About

A small team, a high bar, salt air in the lab.

South OC Peptides was founded with a simple idea: research deserves reagents you can trust. We operate out of South Orange County, California, with sourcing partners audited for purity and consistency. Every lot we release is documented from synthesis to delivery.

Crystalline peptide texture

What we stand for

Purity first

≥99% HPLC purity on research-grade lots, verified by independent labs.

Transparent docs

COA, mass spec, and lot history available with every order.

Fast turnaround

Most orders ship same-day from our California facility.

Researcher support

Real humans answer technical questions, usually within a day.

Our commitment

We sell exclusively to qualified researchers and laboratories. We don't make therapeutic claims, we don't sell for human use, and we don't cut corners. If a lot doesn't pass our internal review, it doesn't leave the building.
