OptiPin is the all-in-one tracker for TRT, peptides and GLP-1 therapy. See how your doses, bloodwork and symptoms trend together over time. Start free: track your first compound completely free, with no time limit and no credit card. Your protocol is scattered across notes, spreadsheets and a pile of reminders. OptiPin replaces all of it with one private place on your phone. No account, no login. Nothing leaves your device unless you ask it to. Why OptiPin? - Every compound side by side: peptides, TRT, anabolics and GLP-1, each with its own schedule, inventory and history - Smart scheduling: daily, weekly or fully custom injection plans, with titration and cycle-off support - Discreet reminders: never miss a dose, with one-tap quick logging - Injection site rotation: a customizable auto-advancing site map so you rotate properly - Track 200+ compounds: peptides, hormones, bloodwork, symptoms, plus your own custom medications and trackers - Bloodwork in one place: snap a photo, enter labs by hand or auto-import from Apple Health and chart them against your dose timeline - Estimated levels: modeled concentration for Testosterone, DHT, E2 and GLP-1s, plus 40+ more compounds - Unit conversion: enter the dose you were prescribed and the strength of your vial. OptiPin turns that into syringe units. You supply every number and it never suggests an amount - Inventory, discard dates and low-stock alerts: never run out mid-protocol or use a vial past its window. Your true cost per dose is here too - Privacy-first: no account, data stays on your device, optional encrypted iCloud backup and CSV export Built for: - Peptide stacks: BPC-157, TB-500, Ipamorelin, AOD9604, MOTS-C, plus blends including GLOW, Wolverine and KLOW - TRT and hormone optimization: testosterone protocols with DHT and full bloodwork - Performance and cycling: track multiple medications and supplements, including custom entries you add yourself - GLP-1 and weight loss: tirzepatide, semaglutide, retatrutide, liraglutide, survodutide, mazdutide OptiPin was built out of a personal need for a smarter, unified way to manage TRT and peptide therapy. Tracking injection sites, staying on top of schedules, managing multiple compounds, keeping symptoms and lab markers in one place instead of juggling notes, spreadsheets and reminders. It keeps growing alongside a community chasing the same thing: clarity and consistency in how they track their protocols.
