About Pepdex: Peptide Calculator
Pepdex is a peptide calculator and tracker that gets the units right. Enter your vial size, the water you added and your own dose, and Pepdex shows how much to draw: units on an insulin syringe, or mL on a standard one. The calculator never suggests a dose. The amount always comes from you and your clinician. FREE, NO ACCOUNT NEEDED • Syringe draw: the units or mL to draw for the dose you enter • Water planner: how much water to add so your dose lands on an easy line to read • Concentration, amount per unit and doses per vial • The peptide and supplement library, and the guides TRACK IT WITH PRO • Protocols on your own schedule for any peptide in the catalog, including GLP-1s, plus TRT or a compound you add yourself • A reminder when each shot is due, with an optional heads-up 30 or 60 minutes early • Vials that count down doses and days left as you log, and a heads-up when one runs low • A one-tap shot log and a calendar of logged, planned and missed shots • Supplements, food, water, workouts, weight and daily check-ins • Scan a vial or supplement label to fill in a new entry, or photograph a meal for a calorie estimate A LIBRARY THAT SHOWS ITS RESEARCH Peptide and supplement entries are graded by how much human research PubMed holds on them, with links to the papers, reported side effects and cautions. Many peptide entries also list questions worth asking a provider. Entries the research can't grade explain why. It is educational reference, not medical advice. ASK COACH Coach is an AI assistant for questions about a compound, a side effect or what the research found. A free account gets 10 Coach messages a day, and Pro includes more. Without an account, Coach answers from the catalog stored on your phone. Coach sees a summary of your tracking only while "Let Coach see my numbers" is on. You can turn that off in Settings and keep using Coach. APPLE HEALTH With your permission, Pepdex reads weight, steps, sleep and other data you choose to share from Apple Health, and, if you turn it on, saves the water you log to Health. FREE AND PRO Free: the calculator, the library and guides, and 10 Coach messages a day with a free account. Pro: tracking (protocols, vials, the shot log, shot reminders, supplements, food, water, workouts, weight and check-ins) and more Coach messages. Pro is an auto-renewing subscription with weekly, 3-month and annual plans. The 3-month and annual plans start with a 7-day free trial for new subscribers. Prices are shown in the app before you subscribe. Pepdex does not sell or ship peptides. It is an information and tracking tool, not medical advice. Talk to your clinician before you start, stop or change anything you take. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Payment is charged to your Apple Account at confirmation of purchase, or when a free trial ends. Manage or cancel in your Apple Account settings.

What’s new
Version 1.0.14 · Updated October 7, 2026
When tracking needs Pro, adding a protocol or a vial now shows what Pro includes, and the free trial when you can get one, before the form. Links inside guides now open the matching screen in the app when there is one. If your iPhone is set to Spanish, the Face ID, Health, camera and photo permission prompts now appear in Spanish. The compounds you track now reach Coach only while "Let Coach see my numbers" is on, the same as your other numbers. You can rate Pepdex any time from Settings. Before you sign in, a few app events, like opening the app, using the calculator and viewing the plans, are counted under a random install ID, never with a compound or an amount. You can turn usage stats off in Settings.
