Peptide tools
Calculators, planners and references for everything between the label on a vial and the line on a syringe. They run in your browser and show their working.
Dose calculator
Vial, water and your prescribed dose in. The mark to draw to out, with a picture of the syringe.
PlannerWater planner
Work backwards: pick how many units you want each dose to be, and see how much water to add.
ConverterUnit converter
mcg, mg, mL and syringe units on one screen. Type any one and see the rest.
ReferenceSyringe guide
What every line on a 30, 50 and 100-unit insulin syringe means, with tables for each.
PlannerVial supply planner
How long a vial lasts on your schedule, when it runs out, and how many a full run needs.
PlannerDose-change planner
When a dose steps up over time, see the units, doses and vials for every step.
CalculatorBlend calculator
Two peptides in one vial: what a draw holds of each, or what to draw for a set amount.
PrintablePrintable draw chart
A one-page dose-to-units table for your exact vial. Print it and keep it with your supplies.
CalculatorUse-by date
Mixing date plus storage days. Know the day to finish a mixed vial.
One idea behind every tool
Mixing a vial spreads a fixed amount of peptide through a set amount of water. Everything else follows from how strong that mix is.
- Strength of the mix: micrograms in the vial ÷ millilitres of water = micrograms per mL.
- Volume for a dose: dose in micrograms ÷ strength = millilitres to draw.
- Syringe units: insulin syringes are U-100, so millilitres × 100 = units.
Example: a 5 mg vial (5,000 mcg) with 2 mL of water is 2,500 mcg per mL. A 250 mcg dose is 0.1 mL, which is 10 units.
This tool does arithmetic on numbers you enter. It does not suggest or check doses. Your dose and how to mix it come from your healthcare professional.
