A four-compound blend combining KPV, GHK-Cu, BPC-157, and TB-500. Each component has its own body of research: KPV in anti-inflammatory contexts, GHK-Cu in skin and collagen research, and BPC-157/TB-500 in tissue-repair research. As with other blends, the specific four-compound combination is a supplier-formulated mix rather than a studied entity on its own.
