GHK-Cu is a specific chemical description
GHK is made from glycine, histidine and lysine. When complexed with copper it is commonly called GHK-Cu. The broader phrase ‘copper peptide’ can cover other materials and formulations.
The name alone does not establish the amount present, complex stability, formulation or whether a product reaches a biologically relevant target.
What the literature investigates
GHK-Cu has been studied in fibroblast cultures, wound models, skin-permeation systems and other experimental settings. These models help investigate mechanisms but are not equivalent to a controlled clinical trial.
To assess a claim about skin appearance, the exact formulation, comparator, duration, measurement method and quality of human research all matter.
Product documentation
A purity percentage is not enough on its own. Identity, analytical method, batch number, laboratory and date must be demonstrably connected to the product shown.
BEL will publish only documents that have actually been received and can be verified. No batch certificate is displayed as if it already existed.
