Retatrutide Dosage Calculation

Yes, drawing 10 units from a 60mg Retatrutide vial reconstituted with 3mL bacteriostatic water will deliver a 2mg dose.

Calculation Explanation

When calculating medication doses from reconstituted solutions, you need to understand the concentration and how your syringe measures the volume:

  1. Concentration calculation:

    • Total amount of medication: 60mg Retatrutide
    • Total volume after reconstitution: 3mL bacteriostatic water
    • Concentration: 60mg ÷ 3mL = 20mg/mL
  2. Dose calculation:

    • Desired dose: 2mg
    • Volume needed: 2mg ÷ 20mg/mL = 0.1mL
  3. Syringe units conversion:

    • Standard insulin syringes measure in "units" where 100 units = 1mL
    • 0.1mL = 10 units on an insulin syringe

Important Considerations

  • Accuracy: Always use an insulin syringe with appropriate markings for small volumes to ensure dosing precision
  • Storage: Reconstituted Retatrutide should be stored according to manufacturer guidelines (typically refrigerated)
  • Sterile technique: Use proper aseptic technique when drawing medication to prevent contamination
  • Expiration: Note the expiration date of the reconstituted solution (typically 14-28 days when using bacteriostatic water)

Administration Tips

  • Ensure the solution is clear and free of particles before administration
  • Rotate injection sites to prevent lipohypertrophy
  • Allow refrigerated medication to reach room temperature before injection
  • Follow proper subcutaneous injection technique

Always verify your calculations when preparing medications, especially for newer medications like Retatrutide where dosing errors could impact both efficacy and side effect profile.
