GHK-Cu Oral Strip

GHK-Cu (Glycyl-L-histidyl-L-lysine copper complex) is an endogenous tripeptide-metal complex found naturally in human plasma, saliva, and urine. First characterized in the 1970s, it has accumulated decades of preclinical evidence as one of the most potent naturally occurring modulators of tissue repair gene expression, influencing the transcription of over 4,000 genes involved in collagen synthesis, antioxidant defense, and anti-inflammatory signaling.

In aesthetic and dermatological research, GHK-Cu has demonstrated the ability to stimulate collagen I and III production, promote skin elasticity and firmness, support hair follicle vitality, and recruit fibroblasts and immune cells to wound sites. The copper(II) ion at its core is considered essential to its biological signaling activity, enabling antioxidant mechanisms that complement its structural repair properties.

Now available as an oral dissolvable strip delivering 5mg of GHK-Cu via sublingual absorption, this format bypasses digestive degradation for enhanced bioavailability. Manufactured in a cGMP-certified facility with third-party testing — no needles, no mixing, no refrigeration required.
