Concentrated Copper Peptide Serum Booster for Skin & Hair (Cu-GHK)
Create your own high-performance skincare or haircare formula—without the high price tag.
Our Concentrated Copper Peptide Serum Booster (Cu-GHK) is designed to be mixed into your existing creams, serums, or hair products. Just a few drops add the benefits of copper peptides to your routine, giving you full control over strength and formulation.
Important: This is a cosmetic booster, not a standalone serum. It must be blended into another product before use.
Why Copper Peptides?
Copper peptides are widely used in cosmetic formulations to support healthier-looking skin and hair.
When added to your products, copper peptides help:
Improve the appearance of skin firmness and elasticity
Smooth the look of fine lines and uneven texture
Support a more even-looking skin tone
Protect against visible signs of environmental stress
Copper peptides are also valued for their antioxidant properties, helping skin look more resilient and refreshed over time.
Benefits for Hair
Copper peptides are commonly used in haircare formulations to support:
Fuller-looking hair
Healthier-looking scalp conditions
Improved hair vitality and appearance
This makes the booster suitable for both skin and hair formulations.
Product Details
Concentration: 1000 ppm CU-GHK stock solution
Appearance: Clear blue liquid (no added dyes)
Bottle size: 10 ml / 0.34 oz
Texture: Water-light
Use: Cosmetic formulation only (must be mixed)
A small amount may not appear blue due to dilution—this is normal and expected.
How to Mix
This is a standardized stock solution used to calculate copper peptide percentages in finished cosmetic products.
Recommended mixing ratios:
2% cream: Add 1 ml (≈25 drops) to 50 ml of cream
30 ml serum: Add 0.6 ml (≈15 drops) and mix gently
Peptides work effectively at very low concentrations. More is not better.

“Good quality, brand new condition and great value for money. The liquid is clear and easy to work with. I’ve used 1% multi‑peptides with copper peptides for a long time and wanted to try a stronger 2% formula, so I mixed this with Matrixyl 10% + HA. It’s early days, but I’m happy so far and will definitely return if things continue well.”
