StackTrackr: Peptide Tracker

Calculate the exact draw, log doses in one tap, and see every injection overlaid on your health trends.

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. Many are FDA-approved and clinician-prescribed; others are research compounds.

ANALYTICS: YOUR DOSES ON YOUR DATA Stop guessing whether your protocol lines up with your numbers. Connect Apple Health 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: resting heart rate, HRV, sleep stages, weight, body composition, nutrition, recovery, and mood • After Doses: compare your metrics before and after each dose, compound by compound • 7 metric groups — Core Vitals, Sleep Stages, Nutrition, Gait & Mobility, Performance & Recovery, State of Mind, Symptoms • 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.

LOG FROM ANYWHERE Log a dose in seconds without opening the app — from your Apple Watch, a Home Screen or Lock Screen widget, or Siri. Your stack lives on your wrist: see today's doses, log or undo, and keep your streak going.

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. StackTrackr adapts to your dosing schedule, not the other way around.

INJECTION TRACKING & DOSE LOG One-tap logging with dose amounts, injection sites, timestamps, and notes. 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.

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.

120+ VERIFIED COMPOUNDS 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.

BUILT FOR REAL PROTOCOLS • GLP-1 weight management protocols — Semaglutide, Tirzepatide, Retatrutide • Peptide stacks for recovery, performance, lean mass, wellness, and anti-aging • TRT and hormone replacement therapy (cypionate, enanthate, propionate) • Body recomposition and muscle-building phases — dose history alongside weight, lean mass, and body-fat trends • Research compound cycles and complex multi-compound stacks • Any injectable protocol requiring precise dose tracking
