Lab reports: third-party tested peptides

Every report on this page comes from an independent laboratory, and every result is written out as text as well as shown as the original document: the lab, report number, test date, product, batch, the purity measured by HPLC and the identity confirmed by mass spectrometry.

We commission tests on our own stock, chosen from sealed packs, and we publish every report we commission, including results that come out above or below the label. Where a lab offers verification, each report carries its verification key so you can check it on the lab's own site.

Reports are listed newest first, each with its product and the lab's report number. Each product page links to the reports for its batch.
