ghk-cu naturally occurring peptide levels decline with age Copper for Anti-Aging & Hair Health GHK-Cu Peptides Before and After:

A high-affinity, saturable transport mechanism for DSIP at the blood-brain barrier was demonstrated in vascularly perfused guinea pig brain, with the highest unidirectional transfer rate in the hippocampus (Kin 1.66 L/min/g) [9]

The effective concentration sits at levels so small they challenge conventional thinking about dose-response relationships in skincare

Here are some of the most notable trials and experiments outlining the peptides potential: According to Kastsiuchenka et al

GHK-Cu and BPC-157 can typically be combined without issues, which simplifies administration for those using both
