Whether you're managing peptides, prescriptions, or personal health therapies, Injectly helps you log every injection, stay on schedule, and understand exactly what's happening between each dose. Enjoy! For supported medications, the Insights tab turns your logbook into a live serum concentration dashboard. Injectly automatically pulls in the applicable medication you've been using, calculates current and projected levels based on your logged dose history and weight, and shows how close you are to peak along with how much of the dose remains active. Features: • Log each injection with dose, medication, date, time, route (SubQ/IM/IV), and injection site so you always have a searchable history — and can rotate sites. • Save and reuse custom protocols for peptides, prescriptions, or personal therapies in a couple of taps. • Reminders that match your cadence — daily, weekly, or specific weekdays — with multiple reminders per protocol and the dose amount shown right in the notification. • Cycles: run on/off schedules (weeks on, weeks off) with reminders that follow the cycle automatically.
