The arithmetic BioHack Track does inside the app, on the open web — reconstitution, blends, titration ladders, cost and unit conversion. No account, no signup, no dose is ever recommended, and the numbers you type stay in your browser.
Named by the question you arrived with rather than by what they output.
Reconstitution calculator — Enter the vial's mg and the bacteriostatic water you are adding. Out comes the concentration, the volume for your dose, and the exact mark on a U-100 syringe, drawn on a real syringe.
Blend dose calculator — Dose by whichever component you are targeting and see what the same draw delivers of the others. This is the one that prevents the most common blend mistake.
GLP-1 titration planner — Semaglutide, tirzepatide and liraglutide ladders mapped onto real dates, with the week you reach maintenance and what a held step does to the rest.
Vial cost calculator — Cost per dose, per mg, per month and per year, how long one vial lasts, and how many you need to buy in a year.
Peptide unit converter — mg, mcg and grams, plus millilitres and insulin units once you give it a concentration. IU stays IU where a compound is defined that way, because there is no honest mass conversion.
No, and none of them will. They convert a number you already have into a different unit or onto a syringe. Deciding what to take is between you and a clinician — see our editorial policy for where we draw that line.
No. Nothing here needs a signup, and nothing you type is sent anywhere — every calculation runs in your own browser.
Because there is no fixed conversion. IU is a measure of biological activity, defined separately for each substance, and HGH and hCG are labelled and dosed that way. Any mg figure would be invented. The converter keeps IU in IU from the label through to the syringe.
Yes — the same arithmetic, published on the open web. In the app they run inline while you log a dose, and the result is saved with it.
