An EU clinic group turned an in-clinic copper-peptide protocol into a private-label retail serum it could actually stand behind
A multi-location EU aesthetic group had the brand and the patients but no formulation or regulatory capability to take its in-clinic GHK-Cu protocol onto a retail shelf. PeptideXpo's OEM workflow carried it from brand brief to a launch-ready finished product.

Challenge
The clinic group ran an in-clinic GHK-Cu treatment across several locations in two EU countries and wanted a take-home serum its patients could buy between visits, under the clinic's own name. What it had: a positioning concept, packaging direction, and a loyal patient base. What it lacked: a stable INCI-compliant formula, an EU CPNP notification pathway, and a manufacturer willing to own the chemistry. Building that capability in-house was a roughly year-long detour, and the retail window the marketing team was aiming at was a fraction of that.
Approach
PeptideXpo ran this as a finished-goods OEM engagement against the clinic's brief rather than a raw-material sale — which is the part of our catalog breadth that mattered here. We sourced the GHK-Cu at cosmetic grade from the same supply we already characterize for copper-peptide buyers, developed an aqueous-gel carrier suited to a copper-bound active, ran the formula through the standard accelerated and real-time stability timepoints, aligned the INCI and supporting documentation to EU CPNP expectations, sourced primary packaging to the clinic's brand spec, and handled finished-goods QC release. The clinic kept what it was best at — secondary packaging, the patient relationship, and the storytelling.
Outcome
The serum reached first commercial shipment comfortably inside the marketing window, with weeks of margin rather than a scramble. Early sell-through through the clinics tracked in the healthy band you'd hope for from a first cosmetic-peptide launch with an existing patient audience, and the CPNP notification — filed on the documentation package we supplied — went through without a documentation-driven round-trip. The clinic now treats the line as a repeatable product it can reorder against, not a one-off project.
“We brought the brand and the trust; PeptideXpo brought the chemistry and the paperwork we had no business trying to build ourselves. The difference between hitting our launch window and missing it was having one partner own everything from the copper-bound active through finished-goods QC.”
