Buy Copper peptides

Copper Peptides are often referred to as a topical alternative to invasive rejuvenation treatments due to their ability to activate the body’s natural skin remodelling processes, non-invasively and effectively.

GHK-Cu is effective in cosmetic formulations at concentrations ranging from 0.1% to 0.5%. A 0.34% strength is considered professional-grade and suitable for targeted anti-aging and skin-repair serums.

What is GHK-Cu?

GHK-Cu (Copper Tripeptide-1) is a peptide composed of three amino acids (glycine–histidine–lysine) bound to a copper ion. Found naturally in human plasma, it plays a key role in wound healing, tissue remodelling, and anti-inflammatory signalling.

It is widely used in skincare for its powerful ability to rejuvenate aged or damaged skin, support collagen synthesis, and reverse visible signs of aging.
