Selank dose calculator

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

Selank 10 mg vial with 2 mL example

A 10 mg Selank vial mixed with 2 mL gives 5 mg/mL, or 5,000 mcg/mL.

A 250 mcg dose is 0.05 mL — just 5 units on a U-100 syringe. Doses this small make a U-100 insulin syringe the practical choice over a larger barrel.

• 10 mg / 2 mL = 5 mg/mL
• 250 mcg / 5,000 mcg per mL = 0.05 mL = 5 U-100 units
• Sub-mg doses are easiest to read on a U-100 syringe

Selank 5 mg vial with 2 mL example

A 5 mg vial mixed with 2 mL gives 2.5 mg/mL, or 2,500 mcg/mL.

The same 250 mcg dose now needs 0.1 mL (10 units). The more dilute vial doubles the volume per dose, which some people find easier to measure accurately than a 5-unit draw.

• 5 mg / 2 mL = 2.5 mg/mL
• 250 mcg / 2,500 mcg per mL = 0.1 mL = 10 U-100 units
• More dilution gives a larger, sometimes easier-to-read draw

Tracking small-volume doses

When draw volumes are very small, the difference between two adjacent unit lines on a syringe matters more, so a 1-unit slip is a larger percentage of the dose. Saving the exact unit count in PepSync helps avoid mistakes between doses.
