Lab Testing & CoA
Every Peptoryx compound is independently tested by ISO 17025-accredited laboratories before it ships. Here's the proof.
Independent Testing
Every batch is sent to a third-party ISO-certified lab before we list it. We have no influence over the results.
Purity Verification
HPLC and mass spectrometry tests confirm identity and purity. Minimum 98% required — we publish whatever the lab reports.
CoA Published
The Certificate of Analysis is linked directly to the product batch. Every document shows lot number, test date, and results.
Current Batch CoAs
CoA documents are provided as PDF from the testing laboratory. Lot numbers are traceable. Contact us if you have questions about any batch.
