TOOLS · DOSING CALCULATOR

Dosing Calculator

Seven calculators in one: peptide reconstitution, HRT volume, HGH IU/mg, blended vials, nasal spray, T-cream clicks, and a half-life blood-level simulator. Exactly the math from the app — no account, right in your browser.

Enter your vial size and BAC water to calculate the exact volume to draw for each dose.

How it works

Reconstitution math is deterministic: concentration is your vial strength divided by the BAC water you add, and volume-to-draw is your dose divided by that concentration. The Half-Life tab layers repeated doses over a pharmacokinetic model (Bateman absorption/elimination for calibrated compounds, relative-shape for peptides) to estimate steady-state peak, trough, and swing — the same engine that draws the blood-level chart in the app. Predicted concentrations run roughly ±15–25% versus real lab work and individual response varies, so use them for protocol timing, not diagnosis.
