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/
