ghk-cu naturally occurring benefits for skin and wound healing is a copper peptide with extensive research supporting its regenerative therapeutic GHK-CU Peptide: The Next Frontier

found only in foods of animal origin Foods that are high in vitamin B 12 (g/100g) include: Liver (2658) Beef and lamb (13 Chicken (trace) Eggs (12.5) Dairy foods (0.32.4) In normal humans the absorption of vitamin B 12 from foods has been shown to vary depending on the quantity and type of protein consumed

Long-term exposure to heat, light, or moisture may reduce peptide stability and should be avoided
