Semax Reconstitution Calculator
Semax is a synthetic neuropeptide studied for cognitive research, frequently paired with Selank. Like Selank, it is often reconstituted at higher concentration for intranasal delivery. Confirm your delivery method before calculating.
For laboratory research use only.
Peptide Reconstitution Calculator
Enter your vial size and bacteriostatic water volume. The calculator outputs the resulting concentration per mL and per insulin syringe unit. For procedural reference only.
Reading the result: If you have a 5mg vial reconstituted with 2mL of BAC water, your concentration is 2,500 mcg/mL. On a U-100 insulin syringe, that's 25 mcg per IU mark.

Semax concentration reference
Pre-computed concentrations for common Semax vial sizes (5 mg, 10 mg) across 1–3 mL of bacteriostatic water. All values assume a U-100 insulin syringe.
| Vial | BAC water | Concentration | Per IU (U-100) |
|---|---|---|---|
| 5 mg | 1 mL | 5,000 mcg/mL | 50 mcg |
| 5 mg | 2 mL | 2,500 mcg/mL | 25 mcg |
| 5 mg | 3 mL | 1,667 mcg/mL | 16.7 mcg |
| 10 mg | 1 mL | 10,000 mcg/mL | 100 mcg |
| 10 mg | 2 mL | 5,000 mcg/mL | 50 mcg |
| 10 mg | 3 mL | 3,333 mcg/mL | 33.3 mcg |
Semax research reference
- Dosing range: 250–600 mcg per dose, 1–3× daily (published research range)
- Administration: Intranasal (most common in research) or subcutaneous
- Storage: Refrigerate after reconstitution; relatively stable, used within 30–60 days.

How the math works
Concentration (mcg/mL) = vial mass (mg) × 1000 ÷ bacteriostatic water volume (mL). For a 10 mg Semax vial reconstituted with 1 mL, that is 10,000 mcg/mL. On a U-100 insulin syringe (100 IU marks per mL), each IU mark holds 100 mcg.
