NAD+ (Nicotinamide Adenine Dinucleotide) is a fundamental redox coenzyme essential for cellular energy metabolism, DNA repair, and sirtuin-mediated aging pathways. Research shows NAD+ levels decline 10-65% with age, and supplementation may restore mitochondrial function and activate longevity pathways.
PEG-MGF (PEGylated Mechano Growth Factor) is a synthetic, stabilized form of the 24-amino acid MGF E-domain peptide derived from the IGF-1Ec splice variant. Research shows it activates satellite cells, promotes myoblast proliferation via MAPK-ERK1/2 signaling, and demonstrates neuroprotective effects through PKCε/Nrf2/HO-1 pathways.
