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 shot log, dose tracker, and vial tracker 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 keeps every protocol in one place. Many are FDA-approved and clinician-prescribed; others are research compounds. TESTOSTERONE AND TRT 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. Track nandrolone and other compounds alongside testosterone in the same protocol. ESTIMATED ACTIVE LEVELS See how much of each compound is estimated to remain in your system, based on published half-life data and your last 28 days of logged doses. ANALYTICS: YOUR DOSES ON YOUR DATA Connect Apple Health and StackTrackr overlays every dose you log onto your health charts. • Dose markers on resting heart rate, HRV, sleep stages, weight, body composition, VO2 max, and recovery • After Doses: compare your metrics before and after each dose, compound by compound • Three health categories, a dashboard of the metrics you star, and trends from 30 days out to a full year LAB REPORTS Upload a PDF or photo of a lab report, or forward it by email. StackTrackr reads every marker with its value, unit, and range, lets you check what it read, then analyzes the confirmed results alongside your stack. Follow each marker over time and set a retest reminder. Not medical advice: review results with a clinician. SHOT LOG AND INJECTION TRACKING One-tap logging with dose amounts, injection sites, timestamps, and notes. Never second-guess when your last shot was or which site you used. VIALS THAT TRACK THEMSELVES Vials deplete automatically as you log, oldest first, so nothing expires unused. See how many doses remain in every vial and the date it runs out, with a low-supply warning before the last dose. 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. PROTOCOLS, CYCLES, AND STACKS Give each compound its own schedule and start date: every day, every other day, every few days, or chosen weekdays such as twice weekly or 5-on-2-off. Change a dose and the compound keeps a record of every change. Group compounds into color-coded protocols with a start date and duration, and run several at once. A logging streak on Home and the Lock Screen. JOURNAL Weight, skin, focus, energy, and hormone check-ins, writing prompts, and your goals for each compound. Free on every plan. 120+ VERIFIED COMPOUNDS A fact-checked database of peptides, hormones, and research compounds with molecular weights, half-lives, and storage guidelines. BUILT FOR REAL PROTOCOLS • Testosterone replacement therapy and hormone protocols • Peptide stacks for recovery, performance, lean mass, wellness, and anti-aging • GLP-1 weight management protocols, including Retatrutide STACKTRACKR PRO Unlock unlimited compounds and protocols, dose-overlay and After Doses analytics, the full trend range, estimated-level detail, and CSV or PDF export. Your data syncs securely across devices and your history is there whenever you open the app. No ads. Disclaimer: StackTrackr is for educational and personal tracking purposes only.
