Split dose calculator Info · 21+
Some protocols call for splitting a weekly dose into two or three smaller injections spread throughout the week. More frequent, smaller doses can keep hormone or peptide levels more stable than a single large injection.
This calculator does that math. Enter your total weekly amount, choose how many doses to split it into, and add your solution’s concentration. You’ll get the dose per injection and the exact syringe draw in mL and U-100 units.

How to use this calculator
Enter one amount and the number of draws you want to divide it across; the calculator returns the per-draw amount and checks that the parts add back to the whole. It keeps the arithmetic consistent when a single measured amount is spread over several smaller draws.
Worked example
Dividing a 2 mg amount across 4 equal draws gives 0.5 mg per draw, and the four draws sum back to the original 2 mg.
