Greg, the good news is you did not ruin the peptide. Tirzepatide dissolves readily in 2.0 mL of bacteriostatic water, and the preservative ratio (0.9% benzyl alcohol) remains completely active and sterile.
All you have done is diluted the concentration by half: - 10 mg dissolved in 1.0 mL = 10 mg/mL concentration. - 10 mg dissolved in 2.0 mL = 5 mg/mL concentration.
Your New Dose Calculation for 2.5 mg: - Prescribed Dose: 2.5 mg - New Concentration: 5 mg/mL - 2.5 mg ÷ 5 mg/mL = 0.50 mL - On a U-100 syringe: 0.50 mL = 50 units.
Instead of drawing 25 units, you will draw 50 units. You will still receive the exact same 2.5 milligrams of active drug. Use our Bacteriostatic Water Dilution Calculator to double-check any diluent ratios before injecting.
