Overview

FOXO4-DRI is a D-retro-inverso peptide studied in senolytic research for its targeting of senescent cells in aging models.

Key research findings

A designed 'senolytic' peptide that disrupts the FOXO4-p53 interaction in senescent ('zombie') cells, selectively triggering their apoptosis. In landmark mouse research it reduced markers of aging and restored fitness — making it one of the most discussed longevity research peptides.

Mechanism of action

Disrupts the FOXO4-p53 interaction in senescent cells, studied for selectively triggering their apoptosis (senolysis).

How to reconstitute

Important

Reconstitute with bacteriostatic water, swirl gently, and refrigerate. Avoid shaking to preserve the peptide.

  1. 1Allow the vial to reach room temperature (15–20 minutes).
  2. 2Swab the stopper with alcohol and let it air dry.
  3. 3Add bacteriostatic water slowly down the vial wall.
  4. 4Swirl gently until dissolved into a clear solution.
  5. 5Refrigerate at 2–8 °C and protect from light.

Quality indicators

Uniform white powder

Lyophilized cake should be white to off-white without discoloration.

Clear solution

Reconstitutes to a clear, colorless, particle-free solution.

Cold-chain integrity

Reconstituted solution requires 2–8 °C storage.

Slight clumping

Small clumps that dissolve completely with gentle swirling are acceptable — shipping can cause minor compaction.

Collapsed or melted appearance

Powder that looks collapsed, melted, or stuck to the vial walls may have been exposed to heat in transit.

Cloudy after reconstitution

Persistent cloudiness, particles, or precipitate after gentle mixing can indicate a degraded or contaminated peptide.

Reported observations & safety

Safety signals reported in the research literature. Compiled for scientific awareness — not medical advice.

  • Highly experimental — because it triggers targeted cell death, off-target and dosing risks are emphasized in the literature.
  • No established human safety profile; all current evidence is preclinical.
