How It Works
1. Concentration
Divide vial amount (mcg) by water volume (mL) to get concentration (mcg/mL).
2. Volume needed
Divide desired dose by concentration to get injection volume in mL.
3. Syringe units
Multiply mL × 100 to get U-100 syringe units (IU).
Example
- 5 mg vial + 2 mL water = 2.5 mg/mL
- Want 250 mcg (0.25 mg)?
- 0.25 ÷ 2.5 = 0.1 mL
- 0.1 mL = 10 units on a U-100 syringe

Semax modulates expression of the BDNF/TrkB system in the rat hippocampus in a research model.
Mechanisms studied in research
The literature describes several pathways studied in vitro and in preclinical models. The items below summarise these mechanisms for information only, with no intended human use.
BDNF / TrkB
Studied for modulation of the BDNF neurotrophic factor and its TrkB receptor in the hippocampus (animal models).
Neuroprotection
Documented in preclinical models of cerebral ischaemia for neuroprotective mechanisms.
Metabolic stability
The sequence modification confers increased stability studied in vitro compared with the native fragment.
