Nootropic peptide
Semax is a fragment of ACTH developed in Russia for stroke recovery and cognitive support. Vials of 5-10 mg in 2 mL bacteriostatic water cover most intranasal dosing protocols.
| Dose | 5 mg vial | 10 mg vial |
|---|---|---|
| 250 mcg | 10units | 5units |
| 500 mcg | 20units | 10units |

Half-life ~30 minutes; effects on BDNF and brain neurochemistry persist much longer. Daily intranasal standard.
Refrigerate after reconstitution. 28-day stability.
Cognitive enhancement, neuroprotection, BDNF elevation. Like Selank, predominantly intranasal use.
The math on this page is correct for the listed vial and BAC-water volume. The decision to reconstitute and inject Semax belongs to you and a clinician who knows your full history — not to a webpage.
Semax most commonly ships as 5 mg or 10 mg of lyophilized powder. The standard reconstitution is 2 mL of bacteriostatic water, which yields clean unit-mark math on a U-100 insulin syringe for the doses used in most protocols.
The standard volume is 2 mL of bacteriostatic water. You can use more (easier to draw, lower concentration) or less (more concentrated, smaller draw volume) without changing the peptide itself — only the syringe math changes. The dose table on this page is pre-calculated for 2 mL.
Half-life ~30 minutes; effects on BDNF and brain neurochemistry persist much longer. Daily intranasal standard.

Cognitive enhancement, neuroprotection, BDNF elevation. Like Selank, predominantly intranasal use.
U-100 insulin syringes (29–31 gauge, 8–13 mm needle) are standard for subcutaneous peptide injection. Each unit on a U-100 syringe equals 0.01 mL. The dose table above shows how many units to draw for each common dose, given the vial size and standard bacteriostatic water volume.
