And that's where they saw those other percentages that I mentioned

Elkholy, N., Hariri, M

GHK-Cu peptide has been researched for its potential across a variety of functions (1) including that it may tighten and reverse the thinning of aging skin structure, supporting the extracellular matrix, that it may restore the skin barrier and moderate texture, hyperpigmentation and lesions, may support tissue repair and mitigate inflammation, may stimulate increasing hair follicle size, may exert antioxidant properties and, finally, may exhibit gene restructuring potential

83 A very recent study presents the trans-sulphuration pathway as being directly beneficial for cancer cells to maintain the redox equilibrium and evade ferroptosis, as, upon inhibition of cysteine import, glutathione synthesis is supplied by cysteine derived from the trans-sulphuration pathway

That distinction matters in a category where "copper peptide" is increasingly used as a marketing term rather than as proof of potency
