At a glance

An experimental peptide designed to study senescent-cell survival.

This profile separates the compound’s scientific background from specification-specific preparation and source schedules. Begin with the research findings and limitations, then select the formulation you want to examine.

How it works

FOXO4-DRI is intended to interfere with the interaction between FOXO4 and p53. Researchers investigate whether disrupting that interaction can alter survival of senescent cells in experimental models.[1][2][3]

Potential benefits & side effects

Interpret each outcome in the context of the study population, formulation and evidence type. Research findings do not establish a personal treatment outcome.

Potential benefits & research findings

The cited work concerns senescent-cell burden and tissue responses. These findings do not establish a clinical anti-aging regimen.[2][3][4]

Read the original publications to see the measured endpoints, comparator, duration and uncertainty. Mechanistic plausibility and a favorable experimental result are different from demonstrated clinical benefit.

Side effects & evidence limitations

Interpret the reported adverse effects together with the study population, route and observation period. Small or short studies can miss uncommon and delayed harms. Evidence from a related compound does not establish the safety of FOXO4-DRI.

Source-reported adverse effects and cautions

  • No human clinical safety or efficacy data currently exist[5]; tolerability in humans remains uncharacterized.
  • Injection-site reactions (mild redness, irritation) may occur with subcutaneous administration[9].
  • Sources are available for independent reading. Individual claims and research schedules have not yet undergone an independent clinical review by Pep Science.

    Source-derived research information. Table phases retain the source’s actual duration; open-ended phases are not converted into a fixed eight-week course. Review the original study before interpreting a schedule.

    Standard / Gradual Approach (3 mL = ~3.33 mg/mL)

    Weeks 1–4Weeks 5–8Weeks 9–12Weeks 13–16
    WeekDaily Dose (mcg)Units (per injection) (mL)
    Weeks 1–4250 mcg7.5 units (0.075 mL)
    Weeks 5–8375 mcg11 units (0.11 mL)
    Weeks 9–12500 mcg15 units (0.15 mL)
    Weeks 13–16500 mcg15 units (0.15 mL)

    Frequency: Inject once daily subcutaneously[6]. This schedule uses the standard 3.0 mL dilution to maintain injection volumes under 0.2 mL for all doses. For ≤10-unit (≤0.10 mL) administrations, consider 30- or 50-unit insulin syringes for improved readability.

    Additional schedule context & duration

    Concise summary of the once-daily regimen.

    • Goal: Selectively clear senescent cells via disruption of FOXO4–p53 binding[1][2].
    • Schedule: Daily subcutaneous injections for 8–16 weeks with gradual dose escalation.
    • Dose Range: 250–500 mcg daily; starting low and titrating upward over time.
    • Reconstitution: 3.0 mL per 10 mg vial (~3.33 mg/mL) for accurate unit measurements.
    • Storage: Lyophilized frozen at −20 °C (−4 °F); reconstituted refrigerated at 2–8 °C (35.6–46.4 °F); avoid repeated freeze–thaw[7].

    Suggested daily titration approach.

    • Start: 250 mcg daily for the first 4 weeks; increase gradually as tolerated.
    • Mid-Phase: 375 mcg daily during Weeks 5–8.
    • Target: 500 mcg daily by Weeks 9–16.
    • Frequency: Once per day (subcutaneous)[6].
    • Cycle Length: 8–16 weeks; longer cycles may use intermittent dosing schedules as tolerated[3].
    • Timing: Any consistent time; rotate injection sites to minimize local irritation.

    Preparation

    Preparation and stability depend on the formulation, diluent, container and handling. The source-specific notes below apply to the selected record.
    Reconstitution Steps
    1. Draw 3.0 mL bacteriostatic water with a sterile syringe.
    2. Inject slowly down the vial wall; avoid foaming.
    3. Gently swirl/roll until dissolved (do not shake)[7].
    4. Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

    Storage Instructions

    Proper storage preserves peptide quality.

    • Lyophilized: Store at −20 °C (−4 °F) or below in dry, dark conditions; minimize moisture exposure[7].
    • Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 1 month when using bacteriostatic water[7].
    • Allow vials to reach room temperature before opening to reduce condensation uptake.
    • If long-term storage of reconstituted solution is needed, aliquot into single-use vials and freeze to minimize degradation[7].

    Injection Technique

    General subcutaneous guidance from clinical best-practice resources[8][9][10].

    • Clean the vial stopper and skin with alcohol; allow to dry[8].
    • Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue (use 90° for adequate fat layer, 45° if thin)[10][11].
    • Do not aspirate for subcutaneous injections; inject slowly and steadily[10].
    • Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy and local irritation[9].
    • Release the pinch and withdraw the needle; apply gentle pressure with gauze if slight bleeding occurs.

    Materials & quantity planning
