raw ghk cu powder 99% Pure Copper Peptides (ghk-cu) | Great for DIY - 1 Gram GHK-Cu Copper Peptide – Anti-Aging

Typical dosing: 1-2mg daily, 5 days per week

Researchers examine GHK-Cu in models involving collagen-associated signaling, skin-cell biology, angiogenesis, wound-response pathways, antioxidant response, and tissue-remodeling behavior

Growth factors such as (e.g., VEGF, platelet-derived growth factor [PDGF] bind to a receptor tyrosine kinase (RTK) on the cell membrane, causing autophosphorylation of the receptor, thus creating docking sites for intracellular signaling proteins

In a landmark study published in the Journal of Investigative Dermatology , researchers found that GHK-Cu was more effective than vitamin C and retinoic acid in stimulating collagen production in aged human skin

Following the incubation, the cells were washed thoroughly and plated for colony-forming assays, allowing for the determination of their proliferative capacity
