Calculate the exact draw. Log the dose in one tap. Then see it on a chart — every injection overlaid on your heart rate, sleep, weight, and recovery.

StackTrackr is the reconstitution calculator, dose tracker, and protocol manager built for peptides, testosterone (TRT), hormone therapy, GLP-1 medications, and research compounds. Semaglutide, Tirzepatide, Retatrutide, BPC-157, CJC-1295 + Ipamorelin, GHK-Cu, AOD-9604, TB-500, testosterone cypionate or enanthate, or a complex multi-compound stack — StackTrackr handles every protocol with precision.

ANALYTICS: YOUR DOSES ON YOUR DATA
Connect Health Connect and StackTrackr overlays every dose you log directly onto your health charts — so injections and trends sit on one timeline, readable at a glance.
• Dose markers on every chart: weight, resting heart rate, sleep stages, nutrition, activity, and recovery
• After Doses: compare your metrics before and after each dose, compound by compound
• Metric groups covering Core Vitals, Sleep Stages, Nutrition, and Performance & Recovery
• A dashboard you build yourself, with sparkline tiles for the numbers you care about
• Zoom from 30 days out to a full year of trends

RECONSTITUTION CALCULATOR
Enter vial amount, bacteriostatic water volume, and target dose — get the exact mL and insulin-unit draw instantly. Supports mcg, mg, and IU conversions. Works with single-compound vials and blend vials with ratio-based dosing, a feature no other tracker offers.

PROTOCOL MANAGEMENT
Daily, every other day, twice weekly, weekly, biweekly, monthly, 5-on-2-off, or fully custom cycles. Run multiple protocols simultaneously with color-coded organization, and set a different time of day for each compound.

INJECTION TRACKING & DOSE LOG
One-tap logging with dose amounts, injection sites, timestamps, and notes. Dose reminders — including follow-ups and interval schedules — make sure nothing slips. Never second-guess when your last dose was or which site you used.

SMART VIAL MANAGEMENT
Vials deplete automatically as you log, oldest first, so nothing expires unused. Know exactly how many doses remain in every vial.

ACTIVE LEVELS
See estimated compound levels over time, based on published half-lives — a 28-day history with a 14-day projection.

COST TRACKING
Add a cost to any compound and see it carried through to cost per dose and total protocol cost.

PER-PROTOCOL STREAKS
Streak tracking for each individual protocol — not just an overall score. Missed a dose? Retroactive recovery lets you log it and keep your streak intact.

VERIFIED COMPOUND LIBRARY
A fact-checked database of peptides, hormones, and research compounds with molecular weights, standard reconstitution volumes, typical dosing ranges, and storage guidelines. Every entry verified against published sources.

JOURNAL & CALENDAR
Note weight, skin, focus, energy, recovery, and mood alongside your dose history, and look back over any period — free on every plan.

BUILT FOR REAL PROTOCOLS
• GLP-1 weight management protocols — Semaglutide, Tirzepatide, Retatrutide
• Peptide stacks for recovery, performance, wellness, and anti-aging
• TRT and hormone replacement therapy (cypionate, enanthate, propionate)
• Research compound cycles and complex multi-compound stacks
