COA included with every batch

About

Built on proof,
not promises.

One Tap Peptides supplies high-purity compounds to qualified researchers, laboratories, and institutions. Every batch ships with a documented Certificate of Analysis.

Our Standard

Purity you can verify, not just claim

The peptide market is crowded with suppliers who make purity claims with nothing to back them up. We built One Tap Peptides around the opposite premise: every batch we sell is COA documented, and every certificate is available before you ever need to ask for it. Built on proof, not promises.

Testing & Verification

Five commitments we don't bend on

01

What Ships With Every Batch

Every batch we release comes with a Certificate of Analysis documenting purity, identity, sterility, and endotoxin screening for that lot.

02

Sourcing Standards

We source from suppliers who provide a Certificate of Analysis with every batch, so identity and purity data are documented and available before you buy.

03

Quality-Focused Sourcing

We select suppliers on documented process controls and consistent batch-to-batch COA data, from raw material through finished vial.

04

Sterility & Endotoxin Screening

Sterility and bacterial endotoxin results for each production run are documented on the COA that ships with your order.

05

Why COAs Ship In The Box

The Certificate of Analysis for your batch ships with your order, not on request and not after the fact. You can see exactly what's documented before you ever have to ask.
