FOX04-DRI

What is FOX04-DRI?

FOXO4-DRI is a designed senolytic peptide that kills senescent cells by breaking the bond between the protein FOXO4 and the tumor suppressor p53, and it scores 4.0-4.5/10 in Caution for one blunt reason: it is one of the most hyped longevity peptides on the market and it has zero human evidence. The mechanism is genuinely clever and the preclinical result is striking, but every bit of that result is in mice or cell culture, led by a single 2017 study in Cell, per Baar 2017.

How it is thought to work

Senolysis: displaces FOXO4 from p53 to push senescent cells into apoptosis

Safety watch-outs

• Any active or suspected cancer: do not use, since broad p53 and apoptosis modulation in an uncharacterized peptide is exactly the wrong…
• Fever, spreading redness, or pus at an injection site (possible infection from non-sterile research-chemical product): stop and seek…
• Any unexplained systemic reaction after injection of an unapproved grey-market peptide: stop and consult a clinician.
