How many insulin units is 250 mcg of Semax from a 10 mg vial?

Reconstituting a 10 mg vial with 2 mL of bacteriostatic water gives 5 mg/mL — about 50 mcg per unit. Drawing 250 mcg is 0.05 mL, or 5 units on a U-100 insulin syringe. This is measurement math, not a dose recommendation.

How many insulin units is 500 mcg of Semax from a 10 mg vial?

Reconstituting a 10 mg vial with 2 mL of bacteriostatic water gives 5 mg/mL — about 50 mcg per unit. Drawing 500 mcg is 0.1 mL, or 10 units on a U-100 insulin syringe. This is measurement math, not a dose recommendation.

Was Semax studied as an injection?

The clinical dosing on record for Semax is intranasal (a 0.1% nasal solution used in Russia), not subcutaneous injection. Semax is not FDA-approved and has no validated injectable dose. The reconstitution math here lets you measure a given microgram amount accurately; it is not a recommendation to inject. Dosing decisions belong with a licensed clinician.

How to reconstitute the 10 mg vial and convert any target dose into insulin units. Reconstitution math and unit conversions for the 10 mg vial. Semax's on-record dosing is intranasal (Russian clinical use); it is not FDA-approved and has no validated injectable dose.

No validated human dose. Semax is a research-use peptide with no FDA-approved dose. The reconstitution math below is exact measurement — a calculator, not advice. Any usage figures are community-reported and clearly labeled, and none of this is medical advice.

Calculate for your vial

Enter the mg on your Semax vial, the bacteriostatic water you added, and your target dose — it works out the exact units to draw on a U-100 insulin syringe, for whatever you personally have.

Check the decimal. A misplaced decimal point here is a 10× dosing error. Re-read every number, and confirm your dose with a licensed clinician before you draw.

Educational only — not a dosing recommendation. This tool does the measurement math; it does not tell you what to take. On a U-100 insulin syringe, 100 units = 1 mL.

1 · Find your dose

Pick what you're using Semax for and how much bacteriostatic water you added — this pulls out the exact units to draw and how often people report using it.

There's no validated dose for this peptide by this route, so we don't show a “units to draw” figure. At 2 mL water this 10 mg vial sits at the concentration above — use the full matrix below to convert any amount a clinician specifies into units.

2 · Reconstitute it cleanly, step by step

How to turn the 10 mg powder into a measured liquid with clean, sterile technique. More water means each insulin unit holds less peptide — easier to measure small amounts accurately.

1
Swab both tops
Wipe the rubber top of the bacteriostatic-water vial and the Semax vial stopper with a fresh alcohol pad, and let them air-dry. Never touch the needle or the stoppers after wiping.
Alcohol swab · let dry
2
Draw the water
First pull 2 mL of air into the syringe and inject it into the bacteriostatic-water vial to equalize the pressure, then draw your 2 mL of water back out. Inject it into the Semax vial down the inside glass wall, not onto the powder.
2 mL BAC water
3
Swirl, don't shake
Gently swirl the 10 mg vial until the powder fully dissolves into a clear liquid. Never shake — shaking can damage the peptide and foam the solution.
Swirl, don't shake
4
Know your strength
The vial is now 5 mg/mL. Each unit on a U-100 syringe holds about 50 mcg.

Re-swab & draw your dose
Wipe the stopper again. With a fresh insulin syringe, pull back 10 units of air and inject it into the vial to equalize the pressure, then draw 10 units (0.1 mL) for a 500 mcg dose.

Store it right
Keep the mixed vial in the fridge, away from light. Use a new sterile syringe every time, never share, and drop used sharps in a proper container.
