ghk-cu peptide uses benefits “Is actually worth it?” is genuinely one of the most common questions in my comments, so let me finally answer it properly., The short version: copper peptides have real research behind them, GHK-Cu Peptides: Unlocking the Copper

The effect was dose-dependent within a specific range, with the most pronounced results between 10 to the negative twelfth and 10 to the negative ninth molar

Biochemistry 40 , 58615869 (2001)

The biological roles proposed for GHK-Cu in the research literature have included effects on collagen and extracellular matrix synthesis (through copper-dependent enzymes including lysyl oxidase), on antioxidant gene networks (where copper participates in both prooxidant and antioxidant chemistry depending on context), on growth factor activity in tissue repair, on hair follicle biology, and on broader transcriptional programs characterized in microarray and RNA-seq studies

Dissected tissue is then permeabilized in 0.5% PBS-Triton (PBS-T) at room temperature for a minimum of 3 hours
