COA Policy & Third-Party Testing

Our Testing Process

Research compounds sold by Genetic Peptides USA are tested by Horizon Analytical, an independent US-based third-party analytical chemistry laboratory. We do not conduct in-house testing. Horizon Analytical is not affiliated with Genetic Peptides USA and is involved solely as an independent testing service. You can verify a certificate with them directly at contact@horizonanalytical.com.

What Gets Tested

A tested lot is analyzed by High-Performance Liquid Chromatography (HPLC) for purity and by Mass Spectrometry for identity. The certificate reports the measured purity figure for that specific lot, not a rounded marketing number and not a generic product sample.

Coverage: read this part carefully

Not every compound in our catalog has a published certificate yet. We publish the ones we have and we do not claim the ones we do not. As of July 2026 there are 11 published lot certificates across the catalog, and that number grows as lots are tested. If a product page shows no certificate, no certificate exists for that lot yet. If you want one before you order, email us and we will tell you where that compound stands rather than promise you something that does not exist.

Where to Find a Certificate

Certificates are published on the product page and in the COA Library. Open the product you are considering and read the certificate before you buy. That is the entire point of publishing them.

Certificates are not shipped in the box. There is no printed certificate inside your order. The certificate lives online, where you can read it before you spend money and where it stays available afterwards.

Lot Number Matching

The lot number on a published certificate identifies the specific batch that certificate describes. Compare it to the lot printed on the vial you receive. If a vial you receive does not match the certificate published for it, email support@geneticpeptidesusa.com with your order number and photos and we will resolve it.

What We Are Working Toward

We are working toward submitting samples from our own inventory directly to the laboratory, so that future certificates reflect testing initiated by Genetic Peptides USA. We would rather tell you that plainly than imply a level of verification we have not reached yet.
