GHK-Cu

Also known as: Copper Peptide GHK-Cu, Glycyl-L-histidyl-L-lysine:copper(II), Loren Pickart Copper Peptide

GHK-Cu is a tripeptide (glycyl-histidyl-lysine) with a strong affinity for copper(II) ions, first isolated from human plasma by Dr. Loren Pickart in 1973. It is found naturally in blood, saliva, and urine, with plasma levels declining significantly from around 200 ng/mL at age 20 to 80 ng/mL by age 60. GHK-Cu stimulates collagen and glycosaminoglycan synthesis, promotes dermal fibroblast proliferation, and has demonstrated the ability to upregulate over 4,000 genes involved in tissue remodeling and anti-inflammatory responses. It is widely used in cosmetic dermatology for its skin-rejuvenating and hair growth-promoting properties.

Dr. Taylor's 2 Cents

GHK-Cu is the Swiss Army knife of skin and tissue health. The gene expression data is staggering — it modulates over 4,000 genes involved in tissue repair. I use it both topically and as an injectable, depending on the clinical goal. For skin rejuvenation and hair regrowth, topical is usually sufficient. For systemic tissue repair and anti-aging, I add the injectable form. It pairs beautifully with BPC-157.
