FOXO4-DRI (10 mg vial)
Once daily subcutaneous protocol for longevity and cellular health research.
FOXO4-DRI is a D-amino-acid mirror peptide that disrupts the FOXO4-p53 interaction senescent cells rely on, pushing them into apoptosis in rodent work. It is among the most experimental compounds here. The protocol below escalates cautiously in spaced courses.
Quick answer: at the standard 10 mg + 1 mL reconstitution, a 500 mcg dose of FOXO4-DRI draws 5 units (0.05 mL) on a U-100 insulin syringe, once daily subcutaneous.
Protocol overview
Dosing & reconstitution
Frequency: Once daily subcutaneous
Typical duration: 8-16 weeks
Reconstitution: 10 mg vial + 1 mL bacteriostatic water = 10 mg/mL. Units below are for a U-100 insulin syringe at this concentration.
| Phase | Dose | Units per injection |
|---|---|---|
| Weeks 1-4 | 250 mcg | 2.5 units (0.025 mL) |
| Weeks 5-8 | 375 mcg | 3.75 units (0.0375 mL) |
| Weeks 9-16 | 500 mcg | 5 units (0.05 mL) |
Units = (dose ÷ concentration) × 100 on a U-100 syringe. Change the vial size or water volume and the calculator redoes all of this for you.

FOXO4-DRI dosing — what the literature actually supports
We publish a schedule when there is a citable human source and we say so when there is not. Filling this space with a number nobody measured would make the page look more complete and be worth less than nothing to you.
Reconstitution and measurement
This part is arithmetic and does not depend on the evidence level. Concentration is vial size divided by the bacteriostatic water you add. Draw volume is your target amount divided by that concentration. Units are draw volume times 100, because a U-100 syringe reads 100 units per millilitre. Common vials for FOXO4-DRI: Not stocked by our featured supplier.
- Wipe the stoppers of both vials with an alcohol swab and let them dry.
- Draw the bacteriostatic water with a sterile syringe and inject it slowly down the inside wall of the peptide vial — never straight onto the powder.
- Swirl gently until the solution is clear. Do not shake; foaming and agitation damage peptides.
- Label the vial with the date and concentration, and refrigerate at 2–8 °C protected from light.
Storage and stability
Important notes
Practical considerations for consistency and safety.
- Use a new sterile insulin syringe for each injection and dispose in a proper sharps container.
- Inject slowly and steadily; wait a few seconds before withdrawing the needle to ensure complete delivery.
- Administer at the same time each day for consistent levels. Setting a daily reminder helps maintain the schedule.
- This compound lacks controlled human safety data. Start with the lowest reported amount and increase gradually while monitoring for any adverse reactions.
- The 10 mg vial size is standard for this compound. Reconstitute with 1 mL bacteriostatic water for a convenient concentration.
How FOXO4-DRI works
A D-retro-inverso peptide designed to disrupt the interaction between FOXO4 and p53 in senescent cells, pushing those cells into apoptosis while sparing healthy ones. It is the best-known designed senolytic peptide.
Benefits & side effects
Potential benefits
- Senolytic peptide targeting senescent cells
- Disrupts FOXO4-p53 interaction
- May support tissue rejuvenation
- Steady escalation required
Possible side effects
- Limited safety data
- Potential for off-target senolytic effects
- Monitor liver function
- Theoretical concern about clearance of needed cells
This list reflects published literature and community reports. Individual responses vary. Not medical advice.
Bloodwork worth tracking
The community-standard practice is a baseline panel before starting, a recheck 8 to 12 weeks in, and another after time off. For FOXO4-DRI, the markers most worth watching:
CMPCBCliver panel
Typical time off: 8-12 wks
Lab panels are how a research protocol stays honest: numbers move before symptoms do. Interpretation belongs with a clinician. Not medical advice.
Lifestyle factors
None of the literature above was run on a background of poor sleep and no protein. These variables move outcomes more reliably than any compound on this site.
- Protein in the 1.6 to 2.2 g/kg range preserves lean mass through any body-composition phase.
- Resistance training 2 to 4 days per week plus 150+ minutes of weekly aerobic work reinforces whatever the protocol is doing.
- Sleep is the recovery window: 7 to 9 hours at consistent times.
- Hydration matters more than usual on compounds with GI or flushing effects: 2 to 3 liters daily.
- Track the variables that matter: weigh-ins, measurements, photos, and labs at sensible intervals.

Quick answers
How many syringe units is a 500 mcg dose of FOXO4-DRI?
At the standard reconstitution of 10 mg with 1 mL bacteriostatic water (10 mg/mL), a 500 mcg dose draws 5 units (0.05 mL) on a U-100 insulin syringe.
How do you reconstitute FOXO4-DRI?
Add 1 mL of bacteriostatic water to the 10 mg vial for 10 mg/mL. Inject the water slowly down the inside wall of the vial, swirl gently without shaking, and refrigerate at 2 to 8 °C after mixing.
How long does a 10 mg vial of FOXO4-DRI last?
About 20 maintenance doses of 500 mcg, roughly 2.9 weeks at once daily subcutaneous.
Does FOXO4-DRI have human trial data?
No. The evidence base is animal and cell studies; the practical dosing shown is community convention, and the page labels it that way.
