FOXO4-DRI (10 mg Vial)
FOXO4-DRI (also known as Proxofim) is a synthetic D-retro-inverso peptide designed to selectively induce apoptosis in senescent cells by disrupting the FOXO4–p53 protein interaction. When this interaction is blocked, p53 translocates to the mitochondria in senescent cells, triggering their programmed death while sparing healthy cells. This educational protocol presents a once-daily subcutaneous approach using a practical dilution for precise insulin-syringe measurements.
Detailed protocol below.
| Week | Daily Dose (mcg) | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–4 | 250 mcg | 7.5 units (0.075 mL) |
| Weeks 5–8 | 375 mcg | 11 units (0.11 mL) |
| Weeks 9–12 | 500 mcg | 15 units (0.15 mL) |
| Weeks 13–16 | 500 mcg | 15 units (0.15 mL) |
- •Peptide Vials (FOXO4-DRI, 10 mg each):
- •Insulin Syringes (U-100):
- •Bacteriostatic Water (10 mL bottles): Use ~3.0 mL per vial for reconstitution.
- •Alcohol Swabs: One for the vial stopper + one for the injection site each day.
