Bondevik GT, Schneede J, Refsum H, et al

This high stability means properly reconstituted GHK-Cu maintains its structure well under appropriate conditions

Excretion Pathways Limited data on combined excretion indicates: Primarily renal elimination of peptide fragments Hepatic metabolism contributes to overall clearance Copper recycling through normal physiological pathways No evidence of accumulation in chronic dosing studies (animal models) The relationship between rapid plasma clearance and prolonged biological effects represents a key area requiring further mechanistic investigation across all three components

Its a query that doesnt have a simple, single answer, as the duration of a B12 shots effects can vary significantly from one person to another
