NextDose.AI vs Profast

Track your testosterone, weight loss, GLP-1s, peptides, and any compound, all in one simple app, with an AI that works from your real logged data. NextDose.AI is the all-in-one tracker for anyone running peptides, GLP-1s (semaglutide, tirzepatide), testosterone/ TRT therapy, or any research compound. Scan your vial, snap your bloodwork, and log every shot. Then watch your estimated pharmacokinetic curves update throughout the day. LOSING WEIGHT ON A GLP-1? Log your weekly shot, track your weight, and watch your progress week by week and month by month. Simple and clear, so you always know where you stand and where you're headed. TRACKING TESTOSTERONE OR TRT? Log your protocol and watch your total testosterone, free testosterone, estradiol, and full panel charted over time, right next to your doses. See how your levels move as your protocol changes. YOUR BLOODWORK, MADE CLEAR Snap any lab or blood test and NextDose transcribes your values, charts every marker over time, and flags what's above or below standard reference ranges with plain-language, research-cited context. It organizes and tracks your numbers. It does not diagnose. AN AI BUILT AROUND YOUR STACK This isn't a notes app with a calendar. NextDose's research assistant draws on your logged data plus a large library of peer-reviewed studies. Ask about dosing windows, half-lives, or how compounds interact, and it surfaces the relevant research next to your own numbers. It always cites the research, never prescribes a dose, and points you back to your physician. KEY FEATURES • Weight & GLP-1 Progress.
