Quick math example
A 10 mg vial mixed with 2 mL gives 5 mg/mL. A 250 mcg dose is 0.05 mL, which equals 5 units on a U-100 syringe.
How the Selank calculation works
Selank is labelled in milligrams per vial. The calculator divides total mg by diluent volume to get concentration, then divides your target by that concentration to return per-dose volume.
Smaller per-dose volumes are easier to read on a U-100 insulin syringe than a regular syringe.
- 10 mg vial = 10,000 mcg total
- 10,000 mcg / 2 mL = 5,000 mcg per mL
- 250 mcg target = 0.05 mL per dose
Tracking small-volume doses
When draw volumes are very small, the difference between two adjacent unit lines on a syringe matters more. Saving the exact unit count in PepSync helps avoid mistakes between doses.
Frequently asked questions
Is Selank 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 stack Selank with Semax?+
Calculate each compound separately so the per-dose volumes are clear. PepSync's stack view can show both protocols on overlapping schedules without combining the math.
What syringe is best for sub-mg Selank doses?+
A U-100 insulin syringe is typical because the smaller unit increments make sub-mg draws readable.
