What is FOXO4-DRI?
FOXO4-DRI is a D-retro-inverso peptide designed to disrupt the FOXO4-p53 interaction inside senescent (zombie) cells, nudging them toward apoptosis. It is the flagship senolytic peptide and is studied in intermittent, pulsed research protocols rather than daily dosing.
Reconstitution
FOXO4-DRI reconstitutes with bacteriostatic water. Draw 2mL down the inside wall of the vial, swirl gently until fully dissolved, and refrigerate. Do not shake.

Reconstitution Guide
Materials Needed
- FOXO4-DRI 5mg lyophilized vial
- Bacteriostatic water (BAC water)
- Insulin syringes (U-100, 29-31 gauge)
- Alcohol swabs
- Sharps container
Step-by-Step Instructions
- Prepare workspace — Clean environment, gather materials, thorough handwashing.
- Clean vial stoppers — Wipe both vials with alcohol swabs. Allow complete drying.
- Draw BAC water — Draw 2mL bacteriostatic water using a sterile syringe.
- Add to peptide — Inject slowly down the inside wall of the vial. Do not spray directly onto the powder.
- Dissolve — Allow a few minutes for complete dissolution. Gentle swirl only — no shaking.
- Verify — Solution should be clear.
- Label and store — Note reconstitution date. Refrigerate immediately.
Dosage Protocol
Concentration Calculations
With 5mg peptide in 2mL BAC water:
- Concentration: 2.50mg/mL (2500mcg/mL)
- Per unit (U-100 syringe): 25mcg per unit

| 5mg | 2.00mL | 200 units |
Research Considerations
Mechanism
By displacing p53 from FOXO4 in senescent cells, FOXO4-DRI is proposed to reactivate p53-driven apoptosis selectively in those cells while sparing healthy ones.
Sourcing for Research
Source from verified suppliers that provide third-party testing and certificates of analysis (COA) for each batch. Compare purity documentation, shipping conditions, and batch traceability before purchasing research materials.
Storage Requirements
Lyophilized (Powder)
- Temperature: -20°C or colder
- Duration: 2+ years
- Conditions: Dry, dark, protected from moisture
Reconstituted

- Duration: 2-3 weeks
- Conditions: Protected from light, never freeze
Safety Considerations
- FOXO4-DRI is a research compound
- Not approved for any indication in any jurisdiction
- Research use only — not for human consumption
- Use sterile technique; never reuse needles or syringes
