GHK-Cu × vertexpeptideslab.org — lab test, June 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.
What portal verification means →Test results
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

118% of label, basis not stated — shown as printed. Reconstituted with 2 mL, a 50-unit draw holds 23.5 mg using the measured mass, against 20 mg on the label — 18% more.
