What GHK-Cu adds to the formulation: Gene expression modulation across hundreds of genes including collagen genes (Type I, III), tissue inhibitors of metalloproteinases, anti-inflammatory mediators Collagen synthesis stimulation, specifically Type I and Type III collagen the structural proteins of skin, connective tissue, and many other tissues Anti-inflammatory signaling through investigated effects on TNF-, IL-6, and NF-B pathways Copper-peptide chemistry effects including cofactor activity for skin-relevant enzymes Skin-research and hair-research applications (the GHK-Cu literature in these areas is substantial) For the GHK-Cu deep-dive, see Copper Peptides Explained
Is the GHK-Cu half life considered a major drawback for research
BPC-157s ability to produce context-dependent nitric oxide regulation distinguishes it from simple vasodilators
The standard GHK-Cu injection frequency is once daily, five days on and two days off, for 4 to 12 weeks followed by a 2 to 4 week break
