Livagen (20 mg Vial)
Livagen (Lys-Glu-Asp-Ala) is a synthetic tetrapeptide bioregulator studied for its effects on peptidase inhibition and epigenetic modulation in aging tissues. Preclinical research demonstrates Livagen strongly inhibits enkephalin-degrading enzymes and induces heterochromatin decondensation with gene reactivation in aged cells. No standardized human dosing exists; this educational protocol presents a once-daily subcutaneous approach based on analogy with similar peptide bioregulators.
Detailed protocol below.
| Week | Daily Dose (mg) | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–2 | 0.5 mg (500 mcg) | 7.5 units (0.075 mL) |
| Weeks 3–4 | 1.0 mg (1000 mcg) | 15 units (0.15 mL) |
| Weeks 5–6 | 1.5 mg (1500 mcg) | 22.5 units (0.225 mL) |
| Weeks 7–12 | 2.0 mg (2000 mcg) | 30 units (0.30 mL) |
- •Peptide Vials (Livagen, 20 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.
