Testing & Transparency

We'd rather show you
than tell you.

Exactly how our formulas are made, what's inside them, and how we prove it — so you can decide for yourself.

Every ingredient, disclosed

We publish the complete INCI list on every product page. No "proprietary blend" hand-waving — what's on the label is what's in the bottle.

Third-party tested

Finished formulas are tested by an independent laboratory — not just by us — for ingredient identity, GHK-Cu concentration, and safety.

Honest dosing

Our serum is formulated at a clinical 2% GHK-Cu (20,000 ppm). The deep blue colour is the copper itself — visible proof the peptide is intact.

The proof

Certificate of Analysis

Independent lab results for our production batches — verifying identity, potency and safety. The 2% on the label is the 2% that reaches you.
