Our Purity Standard
We do not ship any compound below 98% HPLC purity. The majority of our catalog ships at 99%+. If a batch falls below our standard, it is quarantined and not made available for sale.
Individual lot CoA documents are available upon request. Contact support@peplix.bio with your order number.
