FOXO4-DRI Peptide: The Complete Guide - Uses, Mechanism, Dosing, Safety & Research
FOXO4-DRI is a synthetic senolytic peptide engineered to selectively trigger programmed cell death in senescent cells - the dysfunctional "zombie cells" that accumulate with aging and drive tissue deterioration. It works by disrupting a specific protein-protein interaction between FOXO4 and p53 that senescent cells depend on for survival, freeing p53 to initiate the cell's own death cascade while leaving healthy cells largely unaffected. This guide covers what the FOXO4-DRI peptide does, how it works at a mechanistic level, what preclinical research shows across aging and chemotherapy models, dosing context from published studies, safety considerations, and where the evidence - and its gaps - currently stand.
