Wait — did I take my shot yesterday, or the day before? And how far do I pull back on the syringe for this dose? If those questions sound familiar, FitPath was made for you. It's the all-in-one shot tracker, injection-site log, and peptide calculator for GLP-1 weight-loss injections and research-peptide protocols — so the mental load of your routine lives in the app, not in your head. Track Ozempic™, Wegovy™, Mounjaro™, Zepbound™, Rybelsus™, Saxenda™, Victoza™, and Trulicity™, plus research peptides like BPC-157, TB-500, Ipamorelin, CJC-1295, GHK-Cu, Sermorelin, Tesamorelin, PT-141, MOTS-c, and NAD+ — all in one free app. Prefilled pen or vial and syringe — FitPath tracks both. PEPTIDE DOSE REMINDERS Your week is full enough without keeping a dosing calendar in your head. Set each schedule once — weekly for GLP-1 shots, daily, every other day, or your own cadence — and FitPath quietly keeps track. It reminds you at the moment you chose, shows exactly when your last dose was, and logs the next one as taken, skipped, or snoozed with a single tap. No more counting back days on the calendar or texting yourself "took it." PEPTIDE DOSE & RECONSTITUTION CALCULATOR No more napkin math over a vial. Enter your vial size, dose, and bacteriostatic water, and FitPath shows exactly how many units to pull back — on a visual syringe guide — with concentration and doses per vial worked out for you. Draw with confidence every time. DUAL-UNIT DOSING See every dose the way you actually use it: mg, mcg, or IU side by side with insulin-syringe units, like "2.5 mg · 8 units," so what you log matches what you draw. INJECTION SITE ROTATION Sore spots from repeating the same site? An interactive body map shows where each shot went last and helps you rotate — front and back views, per-peptide history. PEPTIDE INVENTORY & VIAL TRACKING Know how many pens and vials you have on hand at a glance, with low-stock, expiration, and discard alerts so you can reorder before you run out — no mid-week surprises. PEPTIDE LIBRARY & RESOURCES Browse an education-only reference of 40+ peptides organized by category and goal — from recovery and sleep to weight management — plus articles, videos, and tips curated to the goals you pick. DETAILED PEPTIDE HISTORY Every dose, every site, every vial — your whole protocol history at a glance, so you always have an answer to "when did I last…?" YOUR DATA, YOUR CONTROL Your data is stored securely in your private account, never sold, and you can delete your account and everything in it, in-app, at any time. Whether it's one weekly GLP-1 injection or a multi-peptide stack with separate schedules and reminders for each, FitPath keeps the whole routine calm, organ FitPath is free. Download the peptide tracker that takes the guesswork out of your routine. HEALTH DISCLAIMER FitPath is for tracking and education only. It does not provide medical advice.
