How to use

Enter the milligrams of peptide in your vial and the volume of bacteriostatic water you'll add. The calculator gives the resulting concentration. Enter your target dose and it shows the volume and units to draw on an insulin syringe (1 mL = 100 units). Draw slowly for accuracy.

Handling notes

  • Use bacteriostatic water (0.9% benzyl alcohol) for multi-use vials.
  • Inject the water slowly down the vial wall — never directly onto the powder.
  • Don't shake; gently swirl until dissolved.
  • Refrigerate (2–8 °C) after reconstitution; most peptides are used within ~28 days.
  • Clean the vial top with alcohol before each draw.
