StackTrackr: Peptide Tracker

Keep track of every shot. Log the dose in one tap, know what is left in the vial and when it runs out, and watch estimated levels rise and fall between injections. Then see it on your health charts: every injection overlaid on heart rate, sleep, weight, and recovery, so you can tell whether a protocol is working.

StackTrackr is the peptide tracker, shot tracker, and reconstitution calculator built for peptides, testosterone (TRT), anabolic and research compounds, and GLP-1 medications. Retatrutide, BPC-157, TB-500, MOTS-c, Tesamorelin, CJC-1295 + Ipamorelin, GHK-Cu, testosterone cypionate or enanthate, nandrolone, or a complex multi-compound stack: StackTrackr handles every protocol with precision.

TESTOSTERONE AND TRT
A testosterone tracker and TRT tracker built for weekly, twice-weekly, and every-other-day injection schedules. Log cypionate, enanthate, or propionate doses, rotate injection sites, and see estimated levels from every shot on one chart.

ESTIMATED ACTIVE LEVELS
See how much of each compound is estimated to remain in your system, based on published half-lives: a 28-day history with a 14-day projection.

ANALYTICS: YOUR DOSES ON YOUR DATA
Connect Health Connect and every dose you log is overlaid on your health charts.
• Dose markers on weight, resting heart rate, sleep stages, nutrition, activity, and recovery
• After Doses: compare your metrics before and after each dose, compound by compound
• A dashboard you build yourself, with trends from 30 days out to a full year

HEALTH CONNECT: WHAT WE READ AND WHY
Connecting is optional. StackTrackr reads only what it charts against your doses: weight and body composition, heart rate and vitals (blood pressure, glucose, oxygen, temperature), sleep stages, steps, distance, calories and cadence, nutrition and hydration. It writes one thing: the weight you log in the Journal. Your health data is shown only to you and never shared.

SHOT LOG AND INJECTION TRACKING
One-tap logging with dose amounts, injection sites, timestamps, and notes. Dose reminders, including follow-ups.

VIALS THAT TRACK THEMSELVES
Vials deplete automatically as you log, oldest first, so nothing expires unused. See doses remaining in every vial and the date it runs out.

RECONSTITUTION CALCULATOR
Enter vial amount, bacteriostatic water volume, and target dose to get the exact mL and insulin-unit draw. Supports mcg, mg, and IU conversions. Works with single-compound vials and blend vials with ratio-based dosing.

PROTOCOLS, CYCLES, AND STACKS
Daily, every other day, twice weekly, weekly, biweekly, monthly, 5-on-2-off, or fully custom cycles. Run multiple protocols at once with color-coded organization, and set a different time of day for each compound. Per-protocol streaks.

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

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.

JOURNAL & CALENDAR
Note weight, skin, focus, energy, recovery, and mood alongside your dose history, free on every plan.

BUILT FOR REAL PROTOCOLS
• Testosterone replacement therapy and hormone protocols (cypionate, enanthate, propionate, nandrolone)
• Peptide stacks for recovery, performance, lean mass, wellness, and anti-aging
• GLP-1 weight management protocols and research compound cycles
