The basic formula Concentration (mg/mL) = Total peptide (mg) Water volume (mL) For a 70mg vial with 3mL water: 70 3 = 23.33 mg/mL Volume to draw (mL) = Desired dose (mg) Concentration (mg/mL) For 2.33mg dose at 23.33 mg/mL: 2.33 23.33 = 0.10mL = 10 units on an insulin syringe Common vial sizes and calculations 42mg vial with 1.8mL water: Concentration: 23.33 mg/mL Standard dose (2.33mg): 10 units Conservative dose (1.165mg): 5 units Vial provides approximately 18 doses at standard protocol 70mg vial with 3mL water: Concentration: 23.33 mg/mL Standard dose (2.33mg): 10 units Conservative dose (1.165mg): 5 units Vial provides approximately 30 doses at standard protocol 70mg vial with 2mL water (higher concentration): Concentration: 35 mg/mL Standard dose (2.33mg): 6.7 units (round to 7) Conservative dose (1.165mg): 3.3 units (round to 3) Smaller volumes make precise measurement more difficult The SeekPeptides peptide calculator automates these calculations for any vial size and desired dose
The benzyl alcohol component permits multi-dose use over a typical 28-day window

If the full dose was delivered (the plunger is fully depressed), the needle was in the subcutaneous tissue (not too shallow or too deep), and no significant amount of liquid leaked from the injection site, the injection was performed correctly
