Most peptide apps are reminders with a calculator stapled on. You're running BPC-157, CJC-1295, Ipamorelin, maybe retatrutide, maybe TRT alongside it. Real vials, real money. And the best record of it is a Notes app you forgot to update or a spreadsheet that lost your reconstitution dates. COMPOUND is the protocol intelligence layer for serious operators. Built on published pharmacology and cited research. Not a timer. Not a generic medication app. The instrument your protocol deserves. STACK ANALYSIS* Enter your full protocol: BPC-157, TB-500, CJC-1295, Ipamorelin, GHK-Cu, tesamorelin, retatrutide, semaglutide, tirzepatide, testosterone. COMPOUND's AI-assisted analysis flags interaction patterns, timing overlaps, redundant pathways, and absorption issues, each one cited to peer-reviewed research. Two compounds hitting the same pathway is a wasted vial; you will see it. It reports what it finds. It does not write your protocol. SIDE-EFFECT CORRELATION* Log quick daily check-ins. COMPOUND maps every symptom against your dose timeline and surfaces the patterns you would not find by hand. Insomnia lining up with evening CJC. Nausea tracking a titration step. Mood dips that follow estradiol troughs. BLOODWORK SCANNER* Photograph or import any lab report. COMPOUND extracts every marker (free T, total T, estradiol, IGF-1, CRP, AST/ALT, A1C, lipids, hematocrit) and plots them on your protocol timeline. Told you're "in range" while the symptoms stay? Bring the trend to your next appointment, not the single number. RECONSTITUTION CALCULATOR Stepped input or plain language*: "10mg vial, 250mcg twice daily." Exact syringe units, vial duration, expiry tracking. Unit conversion for the amount you choose; it does not pick your dose. No mental math at 6am. STACK PHARMACOKINETICS* Your whole protocol on one estimated serum concentration curve, built from published half-lives and your own log. Drag a dose time and watch coverage shift across the day. Cycle calendar, cross-cycle comparison, restart readiness check. 90+ COMPOUND REFERENCE LIBRARY Half-life, mechanism of action, regulatory status, protocol patterns reported in the literature, known interactions, and the key studies with PubMed links. 250+ cited studies. Written for people who read the papers. PROTOCOL CHAT* Ask anything about your own stack. Every answer is grounded in your protocol, your symptom log, your bloodwork, and cited research, not a generic chatbot that does not know what you are running. It shows you the evidence; it does not prescribe. ALSO INCLUDED - Dose logging with injection site rotation and timing analysis - Vial inventory and supply alerts* - Symptom journal with pattern detection - Unlimited protocols, reminders, home screen widget - Apple Health sync: sleep, HRV, resting heart rate, workouts, weight, glucose WHO COMPOUND IS FOR - People running multi-compound peptide protocols - TRT users tired of a single number standing in for how they feel - Reta and tirzepatide users who want more than a shot tracker - Anyone who refuses to guess with vials that cost real money - Researchers who already built the spreadsheet and want it on their phone, smarter PRIVACY Anonymous sign-in. No ad-tech. No tracking SDKs. No data resale. IMPORTANT COMPOUND is not a medical device. It does not diagnose, treat, or prevent any condition, and it does not prescribe, recommend, or adjust doses. All analysis is informational, based on published pharmacological research. Always consult a qualified healthcare provider before starting or modifying any protocol or medication. * Requires COMPOUND PRO subscription. Free to start.

Peptide Calc & Tracker

Dosyne is a private, on-device reconstitution calculator and record-keeping logbook for people who already use peptides and GLP-1s. It converts the numbers you enter and keeps your personal log tidy. It never tells you what to take. RECONSTITUTION CALCULATOR Stop guessing syringe math. Enter the peptide amount in your vial (mg) and the bacteriostatic water you added (mL), then enter the dose you have already decided on. Dosyne converts it into the number of units to draw on a U-100 insulin syringe. It is a unit conversion of the values you type — not a recommendation. DOSE LOG Record every dose in seconds and keep an accurate personal history that stays on your device forever. Track how many doses are left in a vial. REMINDERS Optional reminders help you stay consistent. They show the compound name only, never the amount. INJECTION-SITE BODY MAP Tap a spot on the body map to record where each dose went and see your rotation at a glance — abdomen, thighs, arms, and more. CYCLE PLANNER Map your own on and off weeks for each compound and see your schedule on a calendar — no spreadsheet required. PEPTIDE LIBRARY A clean, descriptive reference for popular peptides and GLP-1s — BPC-157, TB-500, GH peptides, semaglutide and more. What each one is, storage notes, and a reconstitution math example. Descriptive only. APPLE HEALTH Optionally read your weight locally to chart your progress. Nothing health-related leaves your device. PRIVATE BY DESIGN No account. No server. No tracking. Your log stays on your device, and the calculator works fully offline. IMPORTANT — NOT MEDICAL ADVICE Dosyne is a unit-conversion calculator and a personal logbook for record-keeping only. It does not provide medical advice, dosing recommendations, diagnosis, or treatment, and it does not suggest or calculate what dose you should take. Always seek the advice of a qualified doctor or healthcare professional before making any medical decision, and never disregard professional medical advice because of something you read or calculate in this app. By using this app, you agree to the Apple Standard End User License Agreement (EULA) https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
