FOXO4-DRI vs SS-31
| Attribute | FOXO4-DRI Senolytic peptide | SS-31 Elamipretide |
|---|---|---|
| Category | Longevity & Healthy Aging | Mitochondrial Health & Energy |
| Best known for | Senolytic / senescent-cell clearance research | Mitochondrial cardiolipin research |
| In plain English | It blocks a 'don't die' signal in senescent cells so they undergo apoptosis instead of lingering. | SS-31 protects the mitochondria's energy-producing surface by stabilizing cardiolipin, the lipid that makes ATP production efficient. |
| How it works | Disrupts the FOXO4-p53 interaction in senescent cells, freeing p53 to trigger apoptosis selectively in senescent (not healthy) cells. | Binds cardiolipin in the inner mitochondrial membrane, preserving electron transport chain efficiency and reducing reactive oxygen species. |
| Researchers study | Aged mice, fibrosis, frailty, and chemotherapy-induced senescence. | Heart failure, mitochondrial diseases, and age-related mitochondrial decline. |
| Internet discussion | One of the most-hyped longevity peptides on biohacker forums. | Discussed in longevity and athletic performance circles. |
FOXO4-DRI
Senolytic / senescent-cell clearance research
It blocks a 'don't die' signal in senescent cells so they undergo apoptosis instead of lingering.
Disrupts the FOXO4-p53 interaction in senescent cells, freeing p53 to trigger apoptosis selectively in senescent (not healthy) cells.
Aged mice, fibrosis, frailty, and chemotherapy-induced senescence.
One of the most-hyped longevity peptides on biohacker forums.
FOXO4-DRI is a designed senolytic peptide researched for selective clearance of senescent cells.
SS-31
Mitochondrial cardiolipin research
SS-31 protects the mitochondria's energy-producing surface by stabilizing cardiolipin, the lipid that makes ATP production efficient.
Binds cardiolipin in the inner mitochondrial membrane, preserving electron transport chain efficiency and reducing reactive oxygen species.
Heart failure, mitochondrial diseases, and age-related mitochondrial decline.
Discussed in longevity and athletic performance circles.
SS-31 is a mitochondria-targeted peptide that stabilizes cardiolipin in the inner mitochondrial membrane.
