Semaxdosage & bacteriostatic water calculator — stock concentration and syringe units.
Semax is a neuroactive heptapeptide derived from ACTH(4-7), studied in vitro for nootropic-like activity, BDNF upregulation, and neuroprotection. It ships lyophilized in a 10 mg vial and is reconstituted with bacteriostatic water. This calculator presets Semax so you can convert a vial and a water volume into an exact stock concentration and syringe draw.

= 0.05 mL on the 1.0 mL syringe
At 5 mg/mL, draw 0.05 mL to measure 250 mcg.
Molecular weight is informational; the reconstitution math depends only on the mass in the vial and the water you add.
Reconstitute a 10 mg Semax vial with 2 mL of bacteriostatic water:
5
mg/mL
5,000
mcg/mL
To measure 250 mcg at that concentration you would draw 5 units (0.05 mL) on a U-100 insulin syringe. Change the vial size, water, or target in the calculator above for your own numbers.
Stock concentration (mg/mL) for Semax's vial size at common bacteriostatic-water volumes.
| Vial | 1 mL | 2 mL | 3 mL |
|---|---|---|---|
| 10 mg | 10 mg/mL | 5 mg/mL | 3.33 mg/mL |
Multiply mg/mL by 1,000 for mcg/mL. On a U-100 syringe, 1 mL = 100 units.
The volume sets the concentration: 10 mg in 2 mL is 5 mg/mL; 10 mg in 1 mL is 10 mg/mL. Enter your numbers above for the exact concentration and draw.
Divide your target in mcg by the concentration in mcg/mL for the volume in mL, then multiply by 100 for units on a U-100 syringe. The calculator highlights the mark for you.
Refrigerated at 2–8 °C, out of light, in single-use aliquots. Laboratory storage guidance only.
Semax is studied in preclinical, in-vitro neuroscience research on BDNF/NGF upregulation, neuroprotection, and cognition. For laboratory research use only.
