01 Peptide Dose Calculator

Convert a desired dose, vial amount, and reconstitution volume into injection volume in mL and U-100 insulin syringe units.

Outputs: injection volume and syringe units.

02 Reconstitution Calculator

Estimate required BAC water volume by target concentration or by a target dose and desired injection volume.

Outputs: BAC water volume in mL and U-100 unit equivalent.

03 Blend Calculator

Two or more peptides sharing one vial. Set a target dose for one of them and see the draw volume plus how much of every other peptide that same draw delivers.

Outputs: per-peptide concentration, draw volume, syringe units, and delivered amounts.

04 Cost Calculator

Turn vial price, vial size, dose, and dosing interval into cost per milligram, cost per dose after unusable leftover, and the weekly, monthly, and annual run rate. Full Cycle mode totals injections, vials, and cost for a whole cycle, including titration steps.

Outputs: cost per mg, per dose, per week, per month, per year, vial lifespan, and full-cycle vials and cost.

05 Beyond-Use Date Calculator

Add the beyond-use interval to the date a vial was reconstituted to get the discard date and days remaining, using the USP default for preserved multi-dose containers.

Outputs: discard date and days remaining.

06 Titration Schedule Generator

Build a week-by-week dose ramp from the labeled titration ladder for Ozempic, Wegovy, Mounjaro, Zepbound, or Rybelsus, with optional escalation dates.

Outputs: labeled starting, escalation, and maintenance doses as a dated schedule.

07 Missed Dose Helper

Check what each product's label says to do after a missed GLP-1 dose, based on how many days have passed since it was due.

Outputs: take-it-or-skip-it guidance from the FDA-approved label.

08 Half-Life Visualizer

Model how repeated doses accumulate from a half-life and a dosing interval, or how a single dose clears. Plots the modeled decay curve and reports peak, trough, steady state, or the amount left and clearance timeline for one dose.

Outputs: accumulation curve, per-dose peak and trough, time to steady state, single-dose amount left, and 50 to 99 percent clearance times.

09 Track It in the App

These calculators run in your browser. The Peptide Tracker iOS app is a personal log for the doses, schedules, inventory, and injection sites you record yourself.
