Naturally found in human plasma, this complex combines three vital amino acids: glycine, histidine, and lysine, with copper ions to act as a "signal peptide." In the ecosystem of the scalp, GHK-Cu functions as a biological architect, sending specific instructions to cells to initiate repair, dampen inflammation, and jumpstart the hair production cycle

While the meta-analysis did not identify a single "best" depth, the most commonly studied clinical depth is 1.01.5 mm

The analysis was done after the fact rather than as a primary endpoint, and the clocks were measured in blood, so they track systemic aging rather than the brain in particular
