Who We Work With
A formulator needs the copper to survive their carrier. A brand needs a sourcing story it can defend in public. A contract manufacturer needs lot data that holds up at a client's QC. A hair brand needs the chemistry kept strictly cosmetic. Each page below is written for one of them — the work we do, what we hand over, and the questions worth asking before a first lot leaves the atelier.
Four kinds of buyer
Bench formulators working GHK-Cu and AHK-Cu into serums, creams, and ampoules — where coordination integrity, carrier compatibility, and the blue of the lot decide whether the formula holds.

How we work with them
Brand ownersBrands building copper peptide into a hero ingredient — where the sourcing story, the authenticity of the coordination, and COA literacy become part of how the product is sold.
Brand R&D across North America · the EU · the UK · the GCC · Australia
How we work with them
ManufacturersContract manufacturers who need consistent bulk copper-peptide supply, defensible lot data, copper-content verification, and stability evidence that survives a client's incoming-QC.
Contract manufacturing hubs across the EU · North America · South Korea · India · Southeast Asia
How we work with them
Hair & scalpBrands formulating copper peptides into scalp and hair products — kept to cosmetic and educational ground, with the coordination chemistry and carrier stability that a leave-on or rinse-off context demands.

From the Atelier
First response under 12 hours. We send a 25 g sample of the active you specify, the lot's UV-Vis spectrum, the Cu²⁺ : peptide ratio measurement, and a feasibility note for the formulation application you have in mind.
