Semax is a peptide derived from ACTH, developed in Russia and used there in neurology; it is studied for focus, memory and neuroprotection via BDNF. The honest caveat: the Russian clinical work used an intranasal formulation, so the injectable figure is a community convention rather than a trial dose. Community protocols commonly report between 200 and 600 mcg per day by subcutaneous injection — sources differ widely, which is why the reported range is that broad. Semax ships in 5 mg and 10 mg vials of freeze-dried powder, dissolved in bacteriostatic water before measuring. The table below works the concentration for every vial-and-water pairing, and the calculator turns amounts into syringe marks.
Open the Semax calculator →| Concentration | 1 mL water | 2 mL water | 3 mL water | 5 mL water |
|---|---|---|---|---|
| 5 mg vial | 5,000 mcg/mL | 2,500 mcg/mL | 1,667 mcg/mL | 1,000 mcg/mL |
| 10 mg vial | 10,000 mcg/mL | 5,000 mcg/mL | 3,333 mcg/mL | 2,000 mcg/mL |
Concentration = vial contents ÷ water added. It is the same compound at every volume — more water only means a weaker solution, larger syringe marks that are easier to read, and a larger injection volume. On a standard U-100 insulin syringe, one unit is 0.01 mL at any barrel size.
