ghk-cu peptide sublingual – Research InstaMed GHK-Cu - Sublingual Oral
Description
The peptide has been documented to up-regulate or down-regulate at least 4,000 genes in the human genome

doi: 10.1016/j.jconrel.2014.05.029 185 NunesD.LoureiroJ
The peptide is derived from a partial sequence of a larger protein identified in human gastric juice, first characterized in the early 1990s
While this sounds promising, it's a far cry from proven results in humans

These reactions typically appear within hours of injection and resolve within 24-48 hours
