Features
Read full description

Peptide Protocol is a shot log for people following a peptide or GLP-1 routine their clinician set. Log every dose in seconds: the compound, the amount you took and the injection site, exactly as you enter them. Get reminders at the times you choose. Rotate injection sites with a body map that shows where you went last. Keep track of your vials: what you have on hand, mix and expiry dates, and refill alerts before you run out. Check in on energy, sleep, appetite, side effects and weight, and see your own logs side by side week by week. Works for semaglutide, tirzepatide, BPC-157, CJC-1295, ipamorelin, GHK-Cu and 30+ more compounds. Pause a protocol with a return date and it picks up again on the day you choose. Your records stay on your iPhone. IMPORTANT Peptide Protocol is a personal log. It does not compute, suggest, recommend or adjust doses, and it does not provide medical advice, diagnosis or treatment. Enter the dose and amounts your prescriber gave you, and talk to a qualified healthcare professional before any medical decision.

About

VialTrack

Read full description

VialTrack helps you stay clear, consistent, and organized when managing complex personal protocols. Instead of juggling notes, spreadsheets, reminders, and inventory records, VialTrack gives you one private place to understand what you scheduled, what you logged, what you have left, and how your progress is trending over time. Create custom protocols from a compound library, record your chosen dosing schedules and titration phases, log doses in seconds, record injection sites, track symptoms, and follow progress metrics that matter to you. VialTrack also helps you manage reconstituted and unmixed vial inventory so you can better understand what you have on hand and when supply may be running low. For users who want a deeper view of their routine, VialTrack can show mathematical decay illustrations based on the information you enter, helping you visualize schedule timing and protocol history more clearly. These illustrations are not measured blood levels or predictions of clinical effects. Your data stays private. VialTrack is local-first and does not require an account. When iCloud is available, your app data can sync through your private iCloud database. Optional Apple Health syncing can import or export selected metrics with your permission, such as weight, waist circumference, and sleep. VialTrack is designed for personal organization and tracking. It is not a medical device or healthcare provider, and it does not provide medical advice, diagnosis, dosing recommendations, or treatment guidance. Always consult a qualified healthcare professional before starting, changing, or stopping any medication, supplement, protocol, or treatment.
