About Ac-SDKP
Inhibits hematopoietic stem cell entry into S-phase. Blocks TGF-β1-mediated fibroblast activation, reducing collagen deposition. Promotes angiogenesis via VEGF upregulation. Regulated in vivo by ACE enzyme.
About NAD+
NAD+ is a coenzyme central to cellular energy metabolism, serving as an electron carrier in glycolysis, the citric acid cycle, and oxidative phosphorylation. It is also a required substrate for sirtuins (SIRT1–7) and PARP enzymes, which regulate DNA repair, gene expression, and mitochondrial biogenesis. NAD+ levels decline measurably with age; IV or subcutaneous delivery aims to restore intracellular pools more directly than oral precursors such as NMN or NR.
