Peptide Protocol is a peptide and GLP-1 dose tracker. Log every dose in seconds. Track vial inventory and get refill alerts. Rotate injection sites. Check in on energy, sleep, appetite and weight, and see what is actually changing week by week. The Reconstitution Helper does the arithmetic on the values you enter yourself — units, volume and doses per vial. Works with Ozempic, Mounjaro, Wegovy, Zepbound, Retatrutide, semaglutide, tirzepatide, BPC-157, CJC-1295, Ipamorelin, GHK-Cu and 30+ more compounds. Built for the biohacking and longevity crowd: pause your protocol with a return date and it auto-resumes the day you choose. Rotate injection sites, review side-effect patterns week by week, and keep every record local-first on your device. WHO IT IS FOR Peptide Protocol is designed for people who want structure, clarity, and better protocol follow-through without spreadsheet complexity. IMPORTANT Peptide Protocol is for personal organisation and self-tracking only. It does not calculate, recommend, or adjust medication doses and does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional for any medical decisions, including dose amounts, frequency, or changes to your regimen.

The clearest difference is iOS requirement: Peptidy at 15.1 against Peptide Protocol's 18.0. On price, update cadence, ads and in-app purchases there is nothing between them.
