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.

FOR DIETITIANS Manage your clients, build reusable diet templates, and assign plans - a lightweight CRM built right into the app. Give one diet to a whole group of clients for an agreed period: the plan ends by itself, clients are notified, and you can extend or end it early for everyone at once or for a single person. The exported PDF carries your practice: name, contact details and your colour. Keep each client's parameters - height, weight, activity, goal, daily targets, allergies and restrictions - and follow their progress with measurements and a chart. Age, BMI and an estimated daily requirement are worked out for you, and the app warns you before you assign a plan that breaks a client's restrictions. Start free and upgrade anytime. Your data stays yours - you can delete your account and all associated data at any time. *** Premium and Dietitian are auto-renewable subscriptions billed monthly. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel it anytime in your App Store account settings.
