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.
