GHK-Cu

GHK-Cu is the copper(II) complex of glycyl-L-histidyl-L-lysine, a three-residue peptide that was first isolated from human plasma and identified as Gly-His-Lys in the 1970s.^{858356, 7453802} This listing supplies it as a blue lyophilized powder in 50 mg and 100 mg vials for qualified laboratory research. A batch certificate covering identity, quantity, purity and endotoxin for the posted lot is shown on this page.

Batch documentation

The certificate card on this page shows batch RRL-6524116-P, purity 99.48%, dated 27 JUN 2026, lab horizonanalytical.com. The purity PDF names Horizon Analytical as the lab, records receipt on 06/23/2026 and analysis on 06/27/2026 by UPLC/MS, and lists a 100 mg specification with 99.5 mg found against a >98% purity specification. A companion endotoxin report, lot RRL-6524116-E, records a result of <0.05 EU/mL. Both reports list Revitalized Research LLC as the client and say the report can be looked up through horizonanalytical.com.

To match a vial to its paperwork, read the lot number on the label and compare it with the batch on the card and the lot printed on the PDF; they should be the same string. Batch certificates are posted when available, and the full set is kept in the COA library. Our guide on how to verify a peptide COA walks through the label-to-lab checks step by step.

Storage and handling

Keep sealed vials of the dry powder cold, dry and away from light, and let a vial reach room temperature before opening so moisture does not condense on the cake. Because the copper complex is coloured, a visible change in the powder is worth noting in your lab records. Reconstitution water is not included and is sold separately as reconstitution solution. More detail is in peptide storage basics for research labs.
