"GHK influenced the expression of about 4,000 human genes, shifting their expression from a diseased or aged state toward a healthier profile." Pickart et al., BioMed Research International (2014) That's why GHK-Cu shows up in three very different corners of the community: looksmaxxers running a 12% topical serum for skin quality and fine lines, hair-stack users layering it with minoxidil and finasteride (or RU58841 on an AAS cycle) for follicle support, and injury-rehab protocols pairing it with BPC-157 and TB-500 as the "healing trio" for tendons, ligaments, and post-surgical recovery
For aesthetic applications, TB-500s main use is in improving scar appearance, accelerating healing after procedures, and supporting the collagen remodeling phase that determines whether a healed wound leaves smooth or irregular scar tissue
