Dose & Reconstitution Calculators

Turn vial strength, BAC water, and your prescribed dose into the exact units to draw — with a visual syringe and a reverse "how much water" mode.

Reconstitute compounded semaglutide or tirzepatide into syringe units. Keeps compounded and manufactured-pen products clearly separate.

Convert a prescribed weekly testosterone dose and ester concentration into the mL and insulin units per injection.

Reconstitute HCG in International Units and read off the units to draw on a U-100 syringe.

Split a weekly total across the injections you have chosen, then convert each one into syringe units.

Work out mcg per spray and how many sprays make up your dose from a nasal-spray bottle.

Two or more peptides in one shared vial: see the single syringe draw and how many mcg of each component it delivers.

Put your prescriber's titration steps into a dated, editable week-by-week schedule — and, for compounded vials, the units to draw at each step.

Enter your vial and weekly dose to see usable doses, weeks of supply, and cost per week — with the math shown.

Estimate free and bioavailable testosterone from your own labs — total T, SHBG, and albumin — with the Vermeulen equation.

The published 10-item ADAM questionnaire for symptoms of androgen deficiency — a screen, never a diagnosis.

Watch how a single dose decays by half-life, plus optional steady-state accumulation. A simplified, population-average model.

Pick your product (or use your own label) and the date you opened it to get the discard-by date and days remaining, with the source cited.

Estimate your basal metabolic rate and total daily energy expenditure from the Mifflin–St Jeor equation, with an optional protein target.
