GHK-Cu × Pure Peptides — Lab Test, March 2026
This lab doesn't publish a public lookup, so we can't confirm the certificate against the lab's own record. The document was reviewed before publication, but it rests on our review alone.

This is a purity and identity analysis. Sterility, endotoxins, and heavy metals were not screened — a high purity figure says nothing about those.
About this test
Label 85 mg · Lab measured 84.75 mg
100% of label, basis not stated — shown as printed. Reconstituted with 2 mL, a 50-unit draw holds 21.3 mg on both the label figure and the measured one.
One vial from this lot was weighed by the laboratory, not yours. This page reports what the certificate says; it does not recommend a dose.
