Peptide Calculators & Tools

Calculate exactly how many units to draw on your syringe. Enter your vial size, bacteriostatic water volume, and desired dose.

Find evidence-based dosing ranges for any peptide. Adjust for body weight, experience level, and administration route.

Estimate peptide costs per dose, per week, per month, and per year. Enter your vial price and dosing schedule to plan your budget.

Convert any peptide dose to exact mL and syringe units. Enter your desired dose and concentration to see exactly how much to draw on a U-100 insulin syringe.

Plan your peptide supply. Calculate doses per vial, days of supply, and monthly vial consumption based on your dosing schedule and optional wastage.

Find your peptide concentration in mg/mL, mcg per syringe unit, and units per mg. Enter total peptide and diluent volume with a worked dose example.

Convert between insulin syringe units, mL, and mg. Supports U-100, U-50, and U-40 syringes with optional concentration for mg conversions.

Calculate remaining amount after any time period using exponential decay. Enter starting amount, half-life, and elapsed time to see a decay timeline.

Combine two peptides in one syringe. Enter each dose and concentration to calculate individual and total volumes in mL and syringe units.
