Peptide Calculator

Calculate injection volumes for reconstituted peptides

⚠️ Important Safety Information

  • This calculator is for informational purposes only
  • Always consult with a healthcare professional before using peptides
  • Use proper sterile technique when reconstituting and injecting
  • Store reconstituted peptides properly (refrigerated, as directed)

How it works:

  1. Enter the amount of peptide in your vial (usually in mg)
  2. Enter how much bacteriostatic water you'll add (in mL)
  3. Enter your desired dose per injection
  4. Get the exact volume to inject in mL and insulin syringe units

Reconstitution Details

Usually printed on the vial label

Amount you'll add to the vial

Most peptide doses are in mcg (e.g., BPC-157: 250 mcg)

💡 Pro Tips

  • • Always use bacteriostatic water (BAC water) for multi-dose vials
  • • 1 mL = 100 units on a standard insulin syringe (U-100)
  • • Inject water slowly down the side of the vial to avoid damaging peptides
  • • Gently swirl (don't shake) to dissolve - some peptides take time
  • • Store reconstituted peptides in the refrigerator (2-8°C)
  • • Most peptides remain stable for 2-4 weeks after reconstitution
  • • Always discard if solution becomes cloudy or contains particles

📋 Common Examples

BPC-157

5mg vial + 2mL BAC water = 2.5mg/mL (250mcg dose = 0.1mL or 10 units)

TB-500

5mg vial + 2mL BAC water = 2.5mg/mL (2.5mg dose = 1mL or 100 units)

Ipamorelin

2mg vial + 2mL BAC water = 1mg/mL (200mcg dose = 0.2mL or 20 units)
