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 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. 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 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. RECONSTITUTION CALCULATOR Enter vial amount, bacteriostatic water volume, and target dose to get the exact mL and insulin-unit draw instantly. The Unit Converter handles mcg, mg, and IU. Works with single-compound vials and blend vials with ratio-based dosing, including glow and wolverine blends. 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 every step. 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, standard reconstitution volumes, typical dosing ranges, 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.

Pepture is the peptide tracker and GLP-1 dose log built for people who run real protocols and want one clean place to keep every dose, every cycle, every stack, and every result. Log every injection. Plan every cycle. Stack with confidence. Whether you are running GLP-1 for weight management, BPC-157 for recovery, MK-677 for sleep, or a full longevity stack, Pepture turns scattered notes and spreadsheets into a timeline you can actually read. WHAT YOU CAN LOG - Doses in mg, mcg, or IU, with flexible units for every peptide and protocol. - GLP-1 protocols including semaglutide (Ozempic, Wegovy, Rybelsus), tirzepatide (Mounjaro, Zepbound), retatrutide, and liraglutide. - Classic peptides: BPC-157, TB-500, MK-677, MOTS-c, GHK-Cu, CJC-1295, ipamorelin, sermorelin, HGH, hCG, and more. - TRT and HRT protocols with flexible cadences and multi-dose days. - Injection site rotation so you never overuse a site. PROTOCOLS, CYCLES, AND STACKS - Build protocols with start dates, end dates, and cycle length. - Run cycles on and off with progress bars and clear timelines. - Stack multiple peptides into one protocol and track them together. - Set reminders with time-sensitive notifications so a dose is never missed. CALENDAR, JOURNAL, AND PROGRESS - Calendar view with completed, missed, and upcoming doses at a glance. - Journal every injection with notes, photos, sleep, energy, mood, appetite, soreness, and side effects. - Progress photos with before and after comparisons for body composition. - Track weight, measurements, recovery, and performance markers alongside doses. INSIGHTS - Trend charts across 7, 30, 90, and 365 day views. - Trends across sleep, mood, appetite, and recovery so patterns surface alongside your doses. - Apple Health sync for weight and activity, fully opt in. - Export your full log as a PDF or CSV any time. APPLE ECOSYSTEM - Apple Watch support so logging stays quick. - Home screen widget so today's doses are one glance away. - iPhone and iPad with optional encrypted iCloud sync. PRIVATE BY DEFAULT Your data stays on your device. No forced account. Optional iCloud sync is private to you. Nothing is sold, nothing is shared, nothing is mined. Pepture is built so you can keep a serious log without handing it over to a third party. BUILT FOR - Biohackers and longevity enthusiasts running long term peptide stacks. - Athletes tracking recovery and performance peptides. - People on GLP-1 medications who want a cleaner log than a spreadsheet. - Anyone on a TRT, HRT, or hormone optimization protocol. WHY PEPTURE Most trackers are generic pill reminders with no idea what a peptide protocol looks like. Pepture is purpose built for peptides. The injection site rotation, the stack planner, the cycle structure. Every screen reflects how this community actually runs a protocol, and the interface stays clean even when your stack is complex. Whether you searched for a peptide tracker, a GLP-1 or Ozempic log, a Mounjaro or Zepbound journal, a BPC-157 or TB-500 dose log, or a TRT tracker, Pepture is built for that workflow. IMPORTANT This app is for informational tracking only. It is not medical advice and does not diagnose, treat, or prescribe. Always consult your physician or other qualified healthcare provider in addition to using this app, and before making any medical decisions or starting, changing, or stopping any protocol or medication.
