RetaPro: Your Retatrutide Companion The most complete tracker built exclusively for retatrutide. Log every dose, monitor your vials, calculate reconstitution, and stay on top of your full retatrutide protocol — all in one place. Retatrutide Dose Log & Injection Tracker Log every retatrutide injection with a single tap. Track your dose amount, injection site rotation, and the vial you're drawing from. RetaPro keeps a complete injection log so you always know when your last dose was, how much remains in each vial, and where you injected last. Reconstitution & Vial Calculator Take the guesswork out of retatrutide preparation. RetaPro's built-in peptide calculator helps you calculate reconstitution volumes, BAC water ratios, and exact dose per syringe draw — so every injection is precise. Retatrutide Cycle & Protocol Tracker Track your complete retatrutide protocol over time. Set cycle start dates, log dose escalations, and review your full injection history at a glance. Built for precision, not guesswork. Log Meals Your Way Food logging built for retatrutide users. Search a vast food database, scan barcodes, photograph your plate, or describe your meal by voice. Your daily protein, fiber, water, and calorie targets are calculated specifically for you — based on your body stats, activity level, and treatment plan. Monitor Your Weight & Body Composition Add weight entries manually or sync with Apple Health. Track your trend over time with clear charts, monitor your BMI, and see exactly how your body is responding to your retatrutide treatment.
