Peptide LibrarySemax calculator
Semax is a Russian-developed peptide derived from a fragment of ACTH. Its clinical literature is a handful of Russian-language studies in stroke and optic nerve disease, and no trial is registered on ClinicalTrials.gov; it is registered as a medicine only in Russia and has no established human dose elsewhere. Vendors list 10, 5 and 30 mg vials, a sixfold spread in concentration for the same water volume; the tables show that arithmetic only.
Full research profile: Semax. For any other concentration, use the insulin syringe units converter.

Semax reconstitution chart
Concentration and micrograms per mark on a U-100 insulin syringe, by vial size and water added. The peptide amount never changes; only how concentrated it is.
| Vial | + 1 mL water | + 2 mL water | + 3 mL water |
|---|---|---|---|
| 5 mg | 5 mg/mL · 50 mcg per unit | 2.5 mg/mL · 25 mcg per unit | 1.67 mg/mL · 16.7 mcg per unit |
| 10 mg | 10 mg/mL · 100 mcg per unit | 5 mg/mL · 50 mcg per unit | 3.33 mg/mL · 33.3 mcg per unit |
| 30 mg | 30 mg/mL · 300 mcg per unit | 15 mg/mL · 150 mcg per unit | 10 mg/mL · 100 mcg per unit |

Why there is no dose table
No human dose of Semax is established by a published trial, so this page shows concentrations only. The dosage section of the Semax profile lists what the literature does and does not report, with sources.
Common questions
How much bacteriostatic water do you add to a 10 mg Semax vial?
There is no single correct volume: the amount of peptide is fixed and the water only sets the concentration. For 10 mg, 1 mL gives 10 mg/mL (100 mcg per unit), 2 mL gives 5 mg/mL (50 mcg per unit) and 3 mL gives 3.33 mg/mL (33.3 mcg per unit). More water makes each syringe mark hold less, which makes small amounts easier to measure accurately.
What dose does the Semax calculator use?
None. No human dose of Semax is established, so the calculator does not suggest one. It converts a vial size, a water volume and an amount you enter into a volume and syringe units; the tables on this page show concentrations only.
What does one unit on an insulin syringe mean?
A unit is a volume mark, not an amount of drug. On a U-100 syringe 100 units fill 1 mL, so 10 units is always 0.1 mL; how much peptide those 10 units hold depends only on the concentration you mixed. U-40 syringes use 40 marks per mL, so the same volume reads as a different number of units.
