Most clients begin noticing brighter, more even-toned skin after several sessions, with continued improvement over a full treatment course
In research communities, these peptides are often discussed as complementary rather than directly competitive because: GHK-Cu is often chosen for collagen, skin, scar, and cosmetic tissue remodeling goals BPC-157 is often chosen for tendon, ligament, joint, muscle, and deeper recovery goals For that reason, many researchers discussing GHK-Cu vs BPC-157 eventually decide the better question is not which one is better, but which one better matches the tissue target?

No controlled human trial has tested this three-compound combination
Homocysteine levels, which were elevated at baseline, and protein carbonyl groups (a marker of oxidative stress) decreased in a dose-dependent way, with a 37% reduction of homocysteine and a 23% reduction of protein carbonyl groups with 800 mg per day
