Bone, Connective Tissue, and Vascular Effects GHK-Cu promotes bone healing, enhances osteoblastic cell attachment, and increases collagen synthesis in bone cells
This short-acting pulsatile effect makes it suitable for once-daily administration to support physiological GH patterns
It belongs to a class of compounds known as metallopeptides, so its research relevance is directly tied to its ability to bind and transport copper at the cellular level
Petersburg Institute of Bioregulation and Gerontology studied Epithalon across several decades, publishing findings in journals including Annals of the New York Academy of Sciences and Neuro Endocrinology Letters
Chemical penetration enhancers including propylene glycol, dimethyl sulfoxide (DMSO), and various terpenes increase GHK-Cu skin penetration by 2-4 fold, though potential irritation risks require careful optimization
