Why it matters

Why COA transparency matters

In the research-compound space, the label on a vial is not the same as verified content. Third-party testing records give researchers an independent data point about identity and reported amount or purity for a specific batch.

Push for Peptides collects and neutrally summarizes publicly available testing-related records so researchers can compare how openly different supplier listings share COA information. We do not rank suppliers, and a listing is never an endorsement.

Explore COA Analysis

What a COA can and cannot show

Can indicate: identity of the tested compound, reported purity or amount for that sample, and the testing method used.

Cannot prove: that every future batch matches, suitability for any particular purpose, sterility unless separately tested, or anything about human use.
