GHK-Cu is a naturally occurring copper-binding tripeptide complex, supplied as a lyophilized powder. It presents as a characteristic blue powder due to the copper complex.
This peptide appears in literature examining copper transport, extracellular matrix signaling, and dermal fibroblast activity in vitro. Investigators typically reconstitute with bacteriostatic water prior to use in controlled study protocols.
Bacteriostatic water is sold separately and is not included.

COA came through with the shipment and matched the lot on the vial. Packaging was clean and labeling was clear. Ordering process was straightforward.
Shipped same day as promised and arrived in two days. Vial was well protected and the powder was intact with no cracking.
Support answered a labeling question the same day. Would like to see a 20mg option stocked more consistently, but no complaints on the product itself.
