Peptide Protocol is a personal organizer for peptide research and logging, not a prescribing tool. Keep schedules, optional reminders, injection-site notes, and a clear dose history in one place instead of scattered notes. TRACK YOUR PROTOCOLS Add unlimited peptide protocols with custom doses, frequencies, and injection sites. Log doses with one tap and never lose track of your stack again. KNOW WHAT'S IN YOUR SYSTEM Real-time serum level bars show the estimated percentage of each peptide still active in your system based on its half-life. See at a glance when your next dose is due. INJECTION SITE ROTATION Track which sites you've used and get automatic suggestions for your next injection. Proper rotation reduces scar tissue and improves absorption. PEPTIDE LIBRARY A comprehensive reference guide covering 12 of the most researched peptides including BPC-157, TB-500, Ipamorelin, CJC-1295, Semaglutide, Tirzepatide, GHK-Cu, Epithalon, Selank, Semax, PT-141 and LL-37. Each profile includes: ยท Half-life and decay curve ยท Administration routes ยท Mechanism of action ยท Storage instructions VIAL INVENTORY Enter your vial size and concentration and Peptide Dose automatically tracks how many doses you have remaining. Get a warning when you're running low so you never miss a dose due to an empty vial. 7-DAY ADHERENCE HEATMAP See your consistency at a glance with a visual heatmap showing which days you've logged doses. Build your streak and stay accountable to your protocol. DISCLAIMER Peptide Dose is a personal research tracking and organisational tool only. It does not provide medical advice, diagnosis, or treatment recommendations of any kind. You must be 18 or older to use this app. Always consult a qualified healthcare provider before starting any peptide protocol.

Peptily keeps your injection protocol in one place: the dose your prescriber gave you, when it is due, which site to use next, and when to replace the vial. YOUR DOSE, AS PRESCRIBED Enter your dose from your prescription or pharmacy label. Peptily shows it on every reminder exactly as you entered it. NEVER MISS A DOSE A reminder on dose day and one follow-up if it is still due, not a stream of notifications. Your next dose also lives on the Lock Screen, in the Dynamic Island and in a Home Screen widget with a Log button. DOSE STEPS ON YOUR DATES If your prescription changes the dose over the weeks, enter each step once. Reminders and Today follow your steps, so you stop counting weeks in your head. SITE ROTATION YOU CAN SEE Eight sites, color-coded by how recently each was used, with the least recently used one up next. Hitting rested tissue is the whole point. VIAL DATES Note the day you started a vial and the replace-by date from your label. Peptily reminds you three days ahead, so your protocol does not gap. BUILT FOR STACKS Every compound gets its own dose, reminder and site. Switch between them on Today and log each one in a tap. YOURS, ON YOUR DEVICE No account. No sign-up. No server. Your protocol never leaves your phone. Edit or delete any entry, and log a missed dose later. Export a clean PDF when you want to show your clinician. HOW IT WORKS Your first logged dose is on us, with every feature open. After that, Pro keeps the log going, along with dose steps, unlimited compounds and stacks, the site rotation map, your full history with a weight trend, and PDF export. Whatever you have already logged stays readable for free, always. Peptily is a logging and reminder tool. It does not give medical advice or create treatment plans, and it does not sell or source anything. Follow your prescription and talk to your clinician about your protocol. โ LEGAL โ Pro is a weekly, monthly or yearly subscription, or a one-time Lifetime purchase.
