Why this grade
GHK-Cu is the most counterfeited peptide in cosmetics — blue powder is easy to fake, 99% assay is not. Ours is synthesized in-house by solid-phase synthesis, purified to 99%, lyophilized, and shipped cold-chained with the copper-complexation verified per batch.
We publish HPLC purity, copper content by ICP-MS, and acetate salt residuals on every COA. Use at 0.05-0.5% in aqueous phases below pH 7; we provide compatibility notes for your preservative system.
Key benefits
- 99% purity by HPLC with copper content cross-verified by ICP-MS
- In-house solid-phase synthesis — sequence confirmed by MS per batch
- Lyophilized format, cold-chained logistics with temperature log
- Formulation support: preservative compatibility data on request
Technical specification
Ingredient profile
GHK-Cu is the founding member of the copper peptide family — a tripeptide that coordinates a single copper ion and is best known for wound-repair, collagen and elastin signalling. Our material is 99%-plus pure by HPLC, sequence-verified by mass spectrometry, and carries a per-lot copper content by ICP-MS so your label claim is backed by metal data, not inference.
Because the copper-peptide bond is the point of the molecule, we ship temperature-logged cold chain as standard and hold the material under controlled humidity. Typical use in clinical-style serums is 20–200 ppm of the peptide; it is incompatible with EDTA and strong chelators.
The material is vegan and allergen-free, and the regulatory dossier covers REACH registration support for EU buyers. It is the most technically sensitive ingredient in the peptide range — and the one where batch documentation matters most.
