In non-clinical research literature, the GHK-Cu peptide is discussed as a signaling molecule that works at the cellular level, including effects on human genes tied to tissue repair, collagen synthesis, collagen and elastin remodeling, glycosaminoglycan expression, and overall skin quality within controlled laboratory systems
It also contains Vitamin A, C and iron along with fibres
Intravenous use should not be assumed unless a clinician specifically directs it
