stability of ghk cu peptide in solution at room temperature Frontiers Copper tripeptide (GHK-Cu) | Tripeptide

Unlike many peptides that have only injectable research data, GHK-Cu has been tested in published human clinical trials specifically as a topical application with outcomes that compared favorably against gold-standard actives

Typical injection sites include the abdomen (avoiding the navel area), outer thigh, and upper arm

For long-term use, serum copper and ceruloplasmin would need monitoring, and gene expression effects evaluated since GHK can downregulate overexpressed cancer-associated RNAs

If you're already using minoxidil with partial results, adding copper peptides might provide the boost needed for meaningful improvement
