FOXO4-DRIvsSS-31
FOXO4-DRI vs SS-31 — independent comparison of uses, administration, pricing across providers, and key differences. Last reviewed April 21, 2026.
Quick Verdict
Based on clinical evidence and real patient data
A D-amino acid retro-inverso peptide designed to disrupt the interaction between FOXO4 and p53 in senescent cells, triggering apoptosis of these 'zombie cells.' A first-in-class senolytic peptide with potential to clear senescent cell burden.
A mitochondria-targeting tetrapeptide that concentrates in the inner mitochondrial membrane, protecting cardiolipin from oxidative damage. Restores mitochondrial function in aged and metabolically stressed cells, with clinical trials in heart failure and Barth syndrome.
