COA Questions

Quick answers to common questions

A COA is a lab report that documents the purity, identity, and quality controls for a specific batch of peptides. Every product we sell ships with one for its current batch.
Look for three things: the purity percentage from HPLC (we target 99%+), the molecular weight confirmation from mass spectrometry, and the test date. If all three match the label, your batch has been verified.
Yes. Testing is performed by third-party laboratories operating under ISO 17025 accreditation standards.
Every batch, every time — before it is released for sale. If a new batch arrives, a fresh COA is generated and linked to the product page.
