ghk-cu serum france Copper Peptide Face & Neck This high 2% GHK-Cu Restorative Skin Cell

Collagen and matrix biology The first published paper documenting collagen synthesis stimulation by GHK-Cu appeared in 1988: fibroblast cultures increased collagen output when exposed to GHK-Cu at concentrations as low as 10 M, with peak activity around 1 nM (Maquart et al., FEBS Letters, 1988)

Transcriptomic studies have revealed that this peptide influences the expression of more than 4,000 human genes, approximately 6% of the genome

Protect raw powder from moisture and light, refrigerate after opening

the trade-off is they draw and push very viscous liquid a little slower (rarely an issue for watery reconstituted peptides)
