TB-500 + GHK-Cu Recovery Combination

Constituent peptides
Proposed mechanism of synergy
Both component peptides are reported in preclinical work to influence tissue repair pathways — TB-500 through actin sequestration and VEGF-mediated angiogenesis, GHK-Cu through fibroblast stimulation and collagen/elastin synthesis. Proponents argue this produces complementary wound-repair mechanisms: one supporting cellular migration and new vessel formation, the other supporting extracellular matrix remodeling. No published trial evaluates this combination.
