GHK-Cu 50 mg, also known as the copper peptide glycine–histidine–lysine, is a naturally occurring tripeptide that binds copper and plays an important role in the body’s repair and healing processes. It is well known for its ability to stimulate collagen formation, reduce inflammation, and promote the skin’s natural regeneration, making it popular in anti-aging and skin care.

In addition to its skin-improving properties, GHK-Cu has also shown positive effects on wound healing, protection against oxidative stress and stimulation of hair growth. The substance is used in both aesthetic and medical fields, for example to reduce wrinkles and to support faster recovery from injuries.
