Peptide Calculator + takes the guesswork out of peptide dosing, reconstitution, and mixing — so you can focus on your protocol, not the math. Dose Calculator Enter your vial size, bacteriostatic water volume, and desired dose to instantly see exactly how much to draw in your syringe. The app displays units, volume, concentration, and total draws per vial — everything you need at a glance. Supports multiple syringe sizes for precise measurements. Blend Calculator Need to combine multiple peptides like BPC-157 and GLP-1 agonists in a single injection? The blend calculator shows per-peptide and combined draw amounts, making multi-peptide syringes straightforward and accurate. Reconstitution Calculator Not sure how much bacteriostatic water to add to your vial? Enter your desired units per draw and the calculator works in reverse — telling you the exact dilution volume needed for your target concentration. Whether you're working with semaglutide, tirzepatide, or any other peptide, Peptide Calculator + handles the dosage math so you don't have to. Features • Peptide dose calculator with syringe draw amounts • Blend calculator for mixing multiple peptides • Reconstitution calculator for precise dilution • Support for multiple syringe sizes • Clean, intuitive interface Accurate dosing, simple math — built for your protocol.

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/
