The Science Behind Craft Your Own

Raw Peptide Powder UK

GHK-Cu copper peptide powder at 99.6% independently verified purity. Most raw peptide suppliers don't publish their purity testing. We include the Certificate of Analysis on the product page, so you know exactly what you are getting before you buy.

This is the same peptide used in our finished serums, without the premixed base. If you want a higher concentration than our 1% face serum or 10% hair serum, or you prefer to work with your own carrier ingredients, this gives you full control. Ideal for experienced formulators who already have a base formula they trust.

Store in a cool, dry place away from direct sunlight. Third-party batch tested. Shipped from the UK.
