BioPure’s GHK-Cu Peptide Serum brings one of the most studied peptides in skin science into a simple, ready-to-use formula. Our proprietary serum combines GHK-Cu (copper tripeptide-1) with three supporting peptides in a four-peptide complex designed to work together. It was developed from the same technology and testing experience behind our research peptide line, and it is made in the USA.
GHK-Cu is a small tripeptide, glycyl-L-histidyl-L-lysine, bound to a copper ion. It was first isolated by researcher Dr. Loren Pickart in 1973 and has been studied for decades for its role in copper delivery and its interaction with the structural proteins of skin. Published research on GHK-Cu examines collagen, elastin, glycosaminoglycans and the extracellular matrix, which is why copper peptide serums have become a staple in modern skincare.
Our GHK-Cu serum is formulated to support a healthier-looking complexion, including:
BioPure offers GHK-Cu two ways. GHK-Cu 50mg is a lyophilized (freeze-dried) powder for laboratory research and requires reconstitution. The GHK-Cu Peptide Serum is a finished, ready-to-use formula that pairs GHK-Cu with three supporting peptides, so there is nothing to measure or mix.
A GHK-Cu serum is a skincare formula built around GHK-Cu, a copper-binding tripeptide also listed on ingredient labels as copper tripeptide-1. BioPure’s version combines GHK-Cu with three supporting peptides.
GHK-Cu is the most widely studied copper peptide, and it is usually what “copper peptide” refers to in skincare. On ingredient lists it appears as copper tripeptide-1.
The copper ion bound to the GHK peptide gives copper peptide solutions their characteristic blue color.
No. Unlike our lyophilized GHK-Cu, the serum arrives ready to use. No bacteriostatic water is needed.
It is made in the USA by our domestic manufacturing partner and ships from our Chandler, Arizona location.
GLOW is a peptide blend that includes GHK-Cu alongside other peptides such as BPC-157. Our article Why We Sometimes Choose GHK-Cu Over GLOW explains when each makes sense.
