The Atelier
A copper-peptide atelier, not a catalogue.
Headquartered in Shanghai, China, Cupratec runs one specialty — copper-bound peptide actives — under a single lot-data discipline. Our buyers are cosmetic and dermatology brand R&D, hair-scalp programmes, contract manufacturers, and licensed mesotherapy clinics in Asia, the EU, and the Americas.
Inside the Atelier

The video below is a short walk-through of the Cu-peptide production line. Every commercial lot ships from this bench; the lot report you receive comes off these instruments. No stock footage.

How we're organised
Four functions, one specialty.
Cupratec is structured so every buyer-facing decision — pricing, lead time, lot report, regulatory framing — passes through people who own the relevant function. Inquiries land with sales, but QA and R&D review every quote that touches a custom Cu-peptide spec before it goes out.
Function
Cu-Peptide Synthesis
Owns solid-phase peptide synthesis on cosmetic-grade resins, Cu²⁺ titration under controlled pH, purification with Cu-aware buffers, and lyophilisation cycles tuned to hold the complex through drying. Final sign-off on every pilot and scale-up campaign.
Tenure
10–15 years in synthetic peptide manufacturing
Background
Solid-phase peptide synthesis with progressively heavier copper-coordination work; prior pharma-API process development for both research-grade peptide and copper-bound-peptide programmes.
Function
Lot-Data QA
Runs the Cu²⁺ characterisation panel on every lot — ICP-MS / AA for the molar ratio, UV-Vis for the d-d band, CIELab against the in-house master lot, and the 25 / 40 / 60 °C stability series. No lot ships without QA sign-off on the four-line lot report.
Tenure
8–12 years in analytical QA
Background
Analytical method development for transition-metal coordination chemistry and peptide ingredients; calibration / qualification work on the ICP-MS, HPLC, and UV-Vis instruments under the Cupratec analytical SOP.
Function
Custom Cu-Peptide R&D
Bespoke copper-peptide chemistry — biotinylated and palmitoyl variants of GHK-Cu, brand-spec AHK / GHK blends, Cu-Glutathione for antioxidant programmes, and other coordination targets. Pilot synthesis at gram scale, scale-up at 100 g / 500 g / 1 kg.
Tenure
12+ years in copper-coordination peptide chemistry
Background
Doctoral-level training in peptide chemistry with extended exposure to transition-metal coordination; track record on bespoke Cu-peptide chemistry that catalogue suppliers will not take on.
Function
Atelier Sales & Buyer Qualification
Single contact for cosmetic, dermatology, scalp, and licensed mesotherapy buyers. Reviews each inquiry for fit with the B2B policy before pricing, supports the cosmetic-notification documentation pathway (CPNP and equivalents), and runs the clinic-licence verification gate on the mesotherapy lot line.
Tenure
8–10 years in cosmetic-active and clinical-aesthetic B2B sales
Background
Cross-border cosmetic-active commercial relationships; familiarity with cosmetic-INCI notification frameworks across the EU, UK, Japan, Korea, and major MENA / APAC / LATAM markets, plus the clinic-licence landscape for mesotherapy practice.
Individual leader identities are disclosed under NDA at the commercial-relationship stage rather than on the public site. Avatars above are monogram-style identifiers, not photographs; they represent the function, not a specific person.
How we work
Operating since 2013 · 13+ years working with copper-coordinated peptides.
Cupratec started in 2013 as a peptide-synthesis operation supplying research-grade material to academic and cosmetic R&D groups, and over time concentrated the bench on a single chemistry problem: holding Cu(II) on a peptide ligand reliably enough to ship lot after lot with the same characterisation profile.
Today the atelier ships GHK-Cu and AHK-Cu under that discipline, and a growing list of custom Cu-peptide programmes for brand operators who need a coordination chemistry partner — biotinylated GHK-Cu for affinity studies, palmitoyl variants for oil-phase serums, AHK / GHK blends built to a brand's specification, Cu-Glutathione for antioxidant programmes.
Our positioning is deliberately not the cheapest Cu-peptide source. We invest in the lot-data programme (per-lot UV-Vis, ICP-MS / AA copper quantification, 6-month solution stability across three temperatures, ΔE colour against the in-house master lot) because the brands that need a copper-peptide atelier are the brands that read the data.
The regulatory context Cupratec works in is cosmetic — INCI names, cosmetic-product notification (CPNP in the EU and equivalents elsewhere), and clinic-licence verification on the mesotherapy lot line. The buyer-qualification framework is published at /legal/b2b-only.
From the Atelier
Sample a Cupratec lot.
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.
