GHK-Cu Copper Peptide Powder, 99.6% Verified Purity

Raw GHK-Cu copper peptide powder at 99.6% verified purity. This is the ingredient, not a finished product. Built for skincare professionals, cosmetic formulators, and experienced DIY skincare enthusiasts who want full control over concentration, carrier base, and finished format.

Each vial is sealed and air-protected to preserve stability from our UK facility to your bench. The Certificate of Analysis for your batch is published on this product page with the exact HPLC purity result.

Why Choose Raw GHK-Cu Powder Over a Ready-Made Serum?

Control. You choose the concentration, the carrier, and the format. Most off-the-shelf serums lock you into a fixed strength. With raw powder you can formulate anywhere from 0.5% to 2% for skin, or higher for scalp applications, depending on your needs and experience level.

If you would rather skip the formulation work, we also carry a ready-to-use GHK-Cu Face Serum at 1% in a 30ml bottle, and a GHK-Cu Hair Serum at 10% for scalp use.

How to Use GHK-Cu Powder

• You will need a milligram-precision scale and a suitable carrier base (distilled water, hyaluronic acid serum, or your preferred cosmetic vehicle)
• Working concentration is typically 0.5% to 2% for facial formulations, higher for scalp products
• Dissolve powder into your carrier, mix thoroughly, store in a cool dark place
• For external cosmetic use only, not for internal consumption

GHK-Cu is water-soluble and dissolves cleanly into aqueous bases. The blue colour is the copper peptide itself, not a dye, and is the visual confirmation that the peptide is present and hydrated.

Purity and Batch Testing

Every batch of GHK-Cu powder is tested at a UK laboratory using HPLC analysis before it leaves our facility. The COA on this product page shows the exact purity for your batch, typically 99.6% or higher, alongside the test date and method.

Low purity copper peptide is effectively expensive water. We publish the numbers so you can verify, not just take our word for it.
