ghk-cu body cream Copper Peptide Face Cu Copper Peptide Lotion is a high GHK-CU- Cosmetic for Healthy Skin

This study showed effects at very low concentrations (picomolar to nanomolar), which is encouraging for topical application

It binds and activates GHRH receptors on pituitary somatotrophs, directly stimulating growth hormone synthesis and pulsatile release the same signaling axis as endogenous GHRH, but massively extended

There's no overlap with AHK-Cu's copper ion deliveryAMPK activation increases mitochondrial biogenesis and fat oxidation, while AHK-Cu supports the structural collagen matrix

It contains 0.9% benzyl alcohol as a preservative, thanks to which a single peptide vial can be withdrawn from gradually over days to weeks without the solution being spoiled by contamination
