GHK-Cu (50mg)

GHK-Cu is a tiny natural peptide — just three amino acids — that grabs onto copper. It is found in human blood, where its levels drop as we age, and it has one of the broadest and most independently repeated research records of any copper peptide, especially in skin and collagen studies.

What makes it stand out to researchers is that, rather than switching a single receptor on or off, it appears to influence a very large number of genes tied to tissue renewal. The copper it carries is central to many of the mechanisms scientists study.

What researchers study it for:

• Collagen and skin research — decades of studies on firmness and repair
• Wound healing — how difficult wounds close in lab models
• Gene-activity research — its unusually broad signaling effect
• Hair-follicle research — an actively studied area

Much of this work spans cosmetic-science and preclinical studies. It is an established research compound, but material here is provided for laboratory use only.

GHK-Cu is copper-bound by design, which gives it a characteristic blue color and makes its identity straightforward to confirm on a Certificate of Analysis. For skin, collagen, and gene-activity research, consistency from one batch to the next matters a great deal — so being able to check the exact purity of the lot you actually received, instead of a one-size-fits-all data sheet, is a real advantage.

Every batch is tested by an independent, accredited laboratory and ships with a batch-matched Certificate of Analysis (COA) you can verify before buying — confirmed at 99% purity. For research use only. Not for human or animal consumption.
