Peptide Microdosing Calculator ^{MicrodosingCalculator.com}

What this model does: define a fixed phase schedule, and the calculator plots dose-equivalent model levels over time. It shows modeled accumulation while injections continue and washout as medication leaves the system by the selected half-life. The results are dose-equivalent model levels, not measured blood concentrations.

Supply estimate: total milligrams are summed from the displayed simulation window using the selected device type. When pen or vial capacities are configured, supply planning compares all-smallest, mixed, and all-largest capacity options. Retatrutide vial entries are generic capacity estimates only because Retatrutide has no approved commercial retail product data.

Schedule table: choose a first-shot date/time and pen/click basis above. The table shows each scheduled shot number, calendar date, weekday/time, modeled dose, and click count when a click basis is available. Phase rows show the medication's quick click comparison, or the selected/manual click basis.

Reading the chart: the bold teal curve is the cumulative model level (superposition of every active shot). The x-axis uses calendar dates plus model day, and the view continues for 28 days after the final injection to show the washout tail. The faint violet dashed curves are each individual injection's contribution waning over its own half-life. Hover anywhere to see which shots are still active at that moment and how much each is still contributing.

Custom schedules: define dose / interval / repeat-count phases and watch how the cumulative level ramps, re-equilibrates, and washes out as you cross phase boundaries. Presets change with the selected medication.

Caveats: this is a simple immediate-input, first-order decay model. Real absorption is smoother, labels differ by product and country, and patient response varies. Any non-label schedule should go through your prescriber.
