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.

Always consult a qualified healthcare provider before beginning or modifying any peptide, hormone or TRT protocol. Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Whether you're optimizing for fat loss, muscle gain, longevity, recovery or anti aging, Milligram is for people who want to take back control of their health protocols with science-backed confidence. Every other tracker gives you a tidier place to write down what you already did. Milligram models what is actually in your system right now. Every dose charted against every half-life. Everything in the stack with info and the database covering over 3,581 references total. Bloodwork read against what you are actually running. And an AI assistant that answers from your real-time numbers, read against a database made specifically for your protocol, not everyday questions. FEATURES Your Protocol: Everything you run, on one screen. Each compound with its own schedule, dose, vial and supply tracked, and the whole protocol read as one picture rather than being scattered across different notes, files and spreadsheets. Dose tracking: Log every dose, whether that's an injectable or an oral supplement - Milligram works with every compound and every dosing route. Reminders arrive on the protocol's schedule and know which compound, which dose and which injection site. Reconstitution Calculator: Mix any vial, any concentration. Convert mg, mcg, IU, and units for compound preparation. Designed for accurately mixing peptide vials with bacteriostatic water - saved to your compounds for quick reference. Milligram Intelligence: An assistant that already has your stack, your doses, your bloodwork and your Apple Health data loaded. Ask "what do I draw for 5mg from a 10mg vial in 2ml", "how is my weight tracking against my retatrutide cycle", or "did my IGF-1 move on tesamorelin", and get an answer from your own numbers. Level Buildup: See your compound levels build from each trough to peak. Every dose is charted against the published half-life of your compound, so you know exactly when you've reached the right zone at the right titration, how each dose is keeping you there, and how much a missed dose can actually move the needle. Bloodwork: Upload a PDF or a photo of your labs. Every biomarker is extracted and out-of-range values flagged, then kept where they can be read against the compounds that might be moving them. Compound Library: 202 compounds with mechanisms, dose ranges, half-lives, expected timelines and side-effect profiles, each referenced to clinical sources. Retatrutide, tirzepatide and semaglutide. Testosterone esters, Masteron, Anavar. Tesamorelin, BPC-157, GHK-Cu, MK-677, Ipamorelin and CJC-1295. Creatine, Omega-3 Fish Oil, Magnesium, Zinc, Vitamin D3, and more. AI calorie and nutrition tracking: Scan any meal with your camera. Snap a photo, scan a barcode, or scan a nutrition label and Milligram extracts calories, protein, carbs and fat instantly. Track every meal against your daily targets with a clean macro breakdown. Apple Health: Two-way sync for sleep, HRV, vitals, activity, weight and body composition, so protocol data and health data sit in the same timeline.
