Know your peptide

What is GHK-Cu?

GHK-Cu is a naturally occurring copper peptide first isolated from human plasma. It is one of the most researched compounds in skin science, with documented roles in collagen synthesis and tissue remodelling.

Plasma levels drop more than 60% between age 20 and 60 — the basis for its use in regenerative protocols.

Benefits of GHK-Cu

Studies associate GHK-Cu with increased collagen density, improved skin elasticity, faster wound healing and thicker hair growth.

Users typically photograph progress monthly; visible changes usually emerge from week six onward.

How to dose GHK-Cu

Protocols typically run 1–2 mg daily, five days on and two off, for 8–12 week cycles.

Because copper peptides interact with other minerals, keep your clinician informed of any zinc or iron supplementation.

How to use the pen

Store the pen refrigerated between uses. Attach a fresh needle, dial your prescribed dose, press the button until the counter returns to zero, and hold for six seconds before withdrawing.

Most protocols run five days on, two days off — your printed dosing guide covers the exact schedule agreed with your clinician.
