An EU med-aesthetic group launched a private-label GHK-Cu serum within its marketing window
A multi-location EU aesthetic-medicine group wanted a retail copper-peptide serum under its own clinic brand but had no formulation or notification capability in-house. The private-label workflow carried it from signed brief to first shipment inside the window the launch needed.

Challenge
The group ran several clinics across two EU countries and wanted to extend its in-clinic copper-peptide protocol into a retail GHK-Cu serum patients could buy between visits. The marketing lead had the positioning and the carton design but no INCI-compliant formulation, no CPNP notification framework, and no manufacturing partner. Standing the capability up in-house would have overrun the planned launch by many months, and the clinic could not credibly headline a copper peptide without being able to show the copper was genuinely coordinated.
Approach
Cupratec ran the formulation development end to end against the clinic's brief: cosmetic-grade GHK-Cu supply with each lot's UV-Vis spectrum and Cu²⁺ : peptide ratio, a chelator-free near-neutral aqueous-gel carrier tuned to keep the coordination intact, a stability programme across real-time and accelerated conditions, INCI documentation aligned to the EU CPNP pathway, and airless primary packaging in the clinic's brand colour. The clinic owned the carton, the in-clinic story, and the customer relationship; Cupratec owned active sourcing, the coordination chemistry, and the lot-level paperwork that sat under the hero claim.
Outcome
First commercial shipment landed inside the marketing window the launch was scheduled against. The CPNP file was assembled from the documentation Cupratec supplied and cleared without a back-and-forth round on the chemistry, and the clinic's team could answer a customer asking how they knew the copper was bound by pointing at the colour and the ratio rather than at a slogan. Reorders held the same documented coordination state, so the second production run matched the one that launched.
“We came in with the brand and the patients; Cupratec brought the copper chemistry and the notification paperwork. What mattered most was that the sourcing story had a measurement under it — when a customer asked how we knew the copper was really bound, we had an answer that was true.”
