PepChamp is the peptide tracker for serious protocols. Track every injection, manage your inventory, follow expert protocols, and monitor your progress — all in one beautiful, private app. AI DATA SHARING DISCLOSURE PepChamp offers three optional AI-powered features (AI Q&A Assistant, AI Research Helper, and Smart Cycle Planner) that send text you type to Google Gemini AI (operated by Google LLC) for processing. Before any data is sent, the app shows a full-screen consent screen that identifies Google as the recipient, lists exactly what data will and will not be sent, explains how the data is used, links to both Google's and PepChamp's privacy policies, and requires you to tap “I Agree” to proceed. No data is sent without your explicit consent. We never send your email, name, dose logs, blood work, or any other personally identifiable information to the AI service. The Interaction Checker does NOT use AI — it queries a local research-backed database.

Lab name, panel type, and individual marker values are NOT shared. Access is automatically revoked 24 hours after the call's scheduled end time, and immediately on cancellation. Before any booking is confirmed, you are shown a prior-permission consent screen listing every category and asked to tap "I Agree". Full scope at https://pepchampapp.com/privacy.

PepLog is a medication reminder & logbook for people who manage a peptide protocol and want to keep track of their progress & history. It's built around one idea: recording a dose should take seconds, right when it happens, the way a food tracker works. WHAT YOU CAN DO • Log a dose in a couple of taps: amount, time, injection site, and a note • Reconstitution made clear: enter a vial's contents and the water you added, and PepLog derives the concentration and converts the dose amount you enter into syringe units • Track your vials: see how much you have left as you log, when each vial was mixed, how long ago, and what 1 mg measures in it. Finished vials remain in your history • Progress photos: capture on a repeatable angle, compare any two side by side, and watch your timeline build over months • See what you've invested: record what a vial cost and PepLog shows your real spend, your cost per logged dose, and how much of what you mixed you've used • Set reminders on your own schedule, with multiple times a day, and log or snooze straight from the notification • See your consistency: a logging streak, badges, a week view, and a history of everything you've recorded • Track your weight and hydration over time, with your own optional goals NEW IN 1.4.2 - A fresh turquoise design throughout PepLog, with light and dark mode, an updated app icon, and refreshed logos. - Tap the sun or moon next to your profile to switch themes, or tap your profile to open Settings directly. - Vial details show when you mixed, time since mixing, and what 1 mg measures in syringe units. - Stats now defaults to 30 days with a cleaner layout. - Additional injection-site choices include left and right waist and lat, and Sign in with Apple reliability has been improved.
