Calculate concentration and syringe units for any peptide vial. Visual syringe guide shows exactly where to draw.
Reconstitution is fixed arithmetic: concentration equals the vial’s peptide mass divided by the volume of bacteriostatic water added. A 5 mg vial reconstituted with 2 mL gives 2.5 mg/mL, so a 250 mcg dose is 0.1 mL — ten units on a 100-unit insulin syringe. The calculator does that conversion and the unit-marking step, which is where most dosing errors actually happen.
Every tool here is free and runs client-side. A calculator can only be as good as the numbers put into it: where a figure comes from a compound profile, that profile states the evidence behind it and where the evidence stops. None of this is medical advice, and compounds sold for research use are not approved for human consumption.
