About FOXO4-DRI

What it is
FOXO4-DRI is a synthetic D-retro-inverso cell-penetrating peptide designed to act as a senolytic. It disrupts the interaction between the FOXO4 protein and the tumor suppressor p53, which triggers programmed cell death selectively in senescent cells. In cell and rodent studies it has been reported to clear senescent cells and improve some markers of aging. It has not been tested in human clinical trials.
How it works
It disrupts the FOXO4 and p53 interaction, releasing p53 to trigger apoptosis selectively in senescent cells.

Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
