The Library
Two copper peptides. Documented per lot.
A small, characterised library of copper-bound peptide actives — every entry shipped with a UV-Vis spectrum, Cu²⁺ : peptide molar ratio, and 6-month solution-stability data. The library grows only when a new active has been put through the same lot-data programme.

The library
2 characterised Cu-peptides · documented per lot
The library is intentionally small in v0.1. Cupratec is actively characterising additional Cu-peptide actives — biotinylated GHK-Cu for affinity studies, palmitoyl GHK-Cu for oil-phase serums, AHK / GHK blends to brand spec, Cu-Carnosine, Cu-Glutathione, Tetrapeptide-Cu-9, and others — and will add them to the library only once a lot has been put through the full Cu²⁺ panel. If you need an active that's not in the library yet, the custom Cu-peptide programme ships from 25 g pilot scale.
