About the serum
Our GHK-Cu serum delivers a precise 1% concentration of the copper peptide GHK-Cu — 300 mg in every 30 ml bottle — in a lightweight blue gel that absorbs in seconds. The GHK-Cu in every batch is independently HPLC-tested to a minimum 99% purity, with a Certificate of Analysis for each batch. Paired with hyaluronic acid, panthenol and beta-glucan, it's a copper peptide serum made for a simple morning and evening routine, shipped from Lithuania across Europe.
What is GHK-Cu?
GHK-Cu (also written GHKCu, or copper tripeptide-1) is a small complex of three amino acids — glycine, histidine and lysine — bound to copper. It occurs naturally in the body and is one of the most widely studied peptides in skin science. In skincare, it's used as a skin-conditioning ingredient that helps skin look smoother, firmer and more even with regular use.

Copper peptide serum for your daily routine
Apply 2–3 drops after cleansing, morning and night, and press in gently. The gel spreads easily, leaves no sticky film and layers under moisturiser and SPF. Glycerin, sodium PCA and sodium hyaluronate draw moisture into the skin's surface for a plump, hydrated look, while panthenol, allantoin and beta-glucan help skin feel soft and comfortable.
Tested for purity, documented for transparency
Every batch of GHK-Cu is tested by an independent lab using High-Performance Liquid Chromatography (HPLC), the standard method for confirming a peptide's identity and purity. Each batch is verified at a minimum of 99% purity, and the results are recorded in a Certificate of Analysis. Our product is notified on the EU Cosmetic Products Notification Portal (CPNP) and has an EU Responsible Person, as EU law requires.
