Quick math example
A 30 mg vial mixed with 3 mL gives 10 mg/mL. A 1 mg dose is 0.1 mL, which equals 10 units on a U-100 syringe.
How the Semax calculation works
Semax is labelled in milligrams per vial. Concentration is the total mg divided by diluent volume; per-dose volume is your target divided by that concentration.
If using a nasal spray, the per-dose volume is delivered as drops rather than syringe units, but the concentration math is identical.
- 30 mg vial = 30,000 mcg total
- 30,000 mcg / 3 mL = 10,000 mcg per mL
- 1,000 mcg target = 0.1 mL per dose
Diluent choice and storage
Bacteriostatic water is common for multi-dose vials, but specific protocols may require a different diluent. Follow the product label or pharmacy direction first.
Frequently asked questions
Is Semax approved as a medicine?+
Approval status varies by jurisdiction. This page only covers calculator math; for legal and clinical status, check current regulatory guidance.
Can I use this for a nasal spray bottle?+
Yes for the concentration math. Per-dose volume can then be translated to drops based on your spray's drop size, which varies by bottle type.
Why are Semax doses listed in mg and mcg interchangeably?+
Both are common in the literature. The calculator handles the conversion, but always confirm whether your protocol is in mg or mcg before entering a target dose.
