FOXO4 DRI improves spermatogenesis in aged mice through reducing senescence associated secretory phenotype secretion from Leydig cells ScienceDirect A biological miracle is happening in anti aging where the body takes out the trash. The peptide reduced frailty markers by 50% in aged mice, inducing apoptosis (death) only in damaged cells.
