Preliminary evidence suggests that boosting NAD+ levels may support the skins regenerative processes, aiding in cellular repair, supporting mitochondrial function and reducing the buildup of damaged cells
How to choose between GHK-Cu and BPC-157 for a study The choice comes down to the research question, not to a general ranking: Choose GHK-Cu when the research focus is: Skin research (topical wound healing, barrier function, aging) Hair and follicle research Fibroblast and collagen-synthesis mechanisms Copper-dependent enzymatic processes Longevity model work centered on ECM Topical delivery research Choose BPC-157 when the research focus is: Musculoskeletal injury repair (tendon, ligament, muscle) Gastrointestinal repair and inflammation Angiogenesis or vascular-function research Nitric oxide pathway modulation Consider both (in separate study arms) when: The research is a comparative repair-mechanism study The research is mapping the boundary between ECM-driven and angiogenesis-driven repair The research program has the capacity for multi-arm design Combination research what the literature shows For researchers interested in combination-peptide research, TB-500 + BPC-157 is a more mechanistically motivated pairing than GHK-Cu + BPC-157, because TB-500 operates through actin-cytoskeleton and cell-migration pathways that complement BPC-157s angiogenic activity in a way that GHK-Cus ECM remodeling activity does not as directly
For these people, oral BPC-157 offers a practical alternative that may still provide benefit, particularly when combined with newer arginate formulations claiming 90% or better absorption
