04 · Frequently asked questions
What is GHK-Cu?
GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with Cu²⁺) that occurs naturally in human plasma, saliva, and urine. First isolated in the 1970s, it has been studied primarily for skin remodeling, collagen synthesis, wound healing, and anti-inflammatory activity. Published work describes it as a modulator of tissue-repair-related gene expression.
Is GHK-Cu FDA approved?
No. GHK-Cu is not FDA-approved as a drug. It appears in some cosmetic topical formulations, but research-grade GHK-Cu sold in vials is a research chemical not approved for human use.

What has GHK-Cu been studied for?
Published work covers skin remodeling, collagen synthesis, wound healing, and anti-inflammatory activity — including a 2015 review in BioMed Research International describing GHK as a modulator of tissue-repair-related gene expression. Most findings are preclinical; it is also used in cosmetic topical formulations.
