Peptide Calculator

Calculate reconstitution volumes, precise dosing, and syringe units for your peptide protocols. A free clinical tool for healthcare professionals.

Step 1: Peptide Information

Step 2: Reconstitution Solvent

⚠ Default is bacteriostatic water (BAC), but it is not correct for every peptide. Select a peptide above to see its required diluent, recommended mix, storage and route.

💧Reconstitution Tips

For best results when reconstituting peptides:

  • BAC water is the default solvent — but NOT for every peptide
  • AOD-9604, IGF-1, IGF-1 LR3, MGF, Dihexa need 0.6% acetic acid (hydrophobic)
  • ARA-290 needs 7.4 pH phosphate-buffered saline (PBS)
  • Inject solvent slowly against the vial wall — never directly onto powder
  • Gently swirl — never shake
  • Allow to dissolve completely before use
  • Store reconstituted peptides at 2-8°C (refrigerated)

📐Understanding Units

Insulin syringes measure in "units" — here's the conversion:

  • 100 unit syringe = 1mL total volume
  • 1 unit = 0.01mL (10 microliters)
  • 10 units = 0.1mL
  • 50 units = 0.5mL

🧮Quick Formula

The core calculation for dosing:

  • Concentration = Peptide (mg) ÷ Water (mL)
  • Volume needed = Dose (mg) ÷ Concentration (mg/mL)
  • Units to draw = Volume (mL) × 100
