SEMAX
Semax is a synthetic heptapeptide analog of ACTH(4–10) developed in Russia and studied primarily for cognitive enhancement and neuroprotection[1][2]. While intranasal administration is most common in clinical literature, subcutaneous injection offers a convenient once‑daily alternative for research purposes[1][4]. This educational protocol presents a practical SC approach using straightforward reconstitution for accurate insulin‑syringe measurements.
- Reconstitute: Add 3.0 mL bacteriostatic water (max vial capacity) → ~3.33 mg/mL concentration.
- Typical daily range: 300–800 mcg once daily (gradual titration recommended).
- Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL ≈ 33.3 mcg on a U‑100 insulin syringe.
- Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles[2][9].
Standard / Gradual Approach (3 mL = ~3.33 mg/mL)
| Week | Daily Dose (mcg) | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–2 | 300 mcg | 9 units (0.09 mL) |
| Weeks 3–4 | 500 mcg | 15 units (0.15 mL) |
| Weeks 5–6 | 600 mcg | 18 units (0.18 mL) |
| Weeks 7–8 | 800 mcg | 24 units (0.24 mL) |
For ≤10‑unit (≤0.10 mL) administrations, consider 30‑ or 50‑unit insulin syringes for improved readability.
Frequency: Inject once daily subcutaneously[1][4]. This schedule uses the largest practical dilution (3.0 mL) to ensure per‑injection volumes are accurate and manageable. Most human nootropic studies use intranasal dosing in the range of 400–900 mcg/day divided into multiple administrations[2][3]; this SC protocol delivers comparable total daily amounts in a single injection for convenience.
Reconstitution Steps
- Draw 3.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming.
- Gently swirl/roll until dissolved (do not shake vigorously).
- Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light[2].
