Lost or stolen packages are covered only if you added shipment protection at checkout. See our Shipping Policy for details.

How do I access Certificate of Analysis?

A Certificate of Analysis (COA) is the lab report for a specific batch of a compound, showing its test results. You can find COAs two ways: on the COAs page in our top menu, where all reports are listed, or on each product’s page, where the COA for that compound is shown with its listing. If you can’t find the report for your batch, contact us at info@pepxcompounds.com with your order number.

Are your compounds third-party tested?

Yes. Every batch is tested by an independent third-party laboratory using HPLC to verify purity, which is 99% or higher. Results are documented in a Certificate of Analysis (COA) for each batch.

No. All products from PEPX Compounds are supplied strictly for laboratory research use only. They are not for human or veterinary use, and they are not drugs, foods, or supplements. They are not intended to diagnose, treat, cure, or prevent any disease.
