OptyPeptides vs Peptily

OptyPeptides is the only peptide tracker built with smart recommendations, helping you confidently start, track, and optimize your peptide protocols. Whether you're just getting started or refining your stack, OptyPeptides gives you the clarity, structure, and insights you need without the overwhelm.

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. — LEGAL — Pro is a weekly, monthly or yearly subscription, or a one-time Lifetime purchase.
