Staying consistent is the hardest part of any peptide protocol. You're juggling multiple compounds, different frequencies, varying dose times — and one missed dose can throw off your entire schedule. PepLog exists so you never have to keep track of it all in your head. HOW IT WORKS Set up your protocol once and let PepLog handle the rest. It builds your schedule, sends you reminders at the right times, and lets you mark doses as taken with one tap — from a Home Screen widget, without even opening the app. WHAT YOU GET Flexible Scheduling — Daily, alternating days, every N-days, or specific weekdays. Configure one to four doses per day with custom dose times. Home Screen Widget — See today's pending and completed doses at a glance. Peptide name, amount, and time — all visible without opening the app. Tap to log instantly. One-Tap Dose Logging — Mark doses complete from the widget or inside the app. No forms, no friction. Multi-Peptide Support — Run multiple protocols simultaneously, each with its own frequency, dosage, and schedule. Smart Reminders — Get notified at your exact dose times so nothing slips through the cracks. Full Dose History — A complete, timestamped log of every dose across all your experiments. See what you took, when, and how much. Supply Duration — Know how many days your vials will last so you can reorder before running out. Your protocol, on autopilot.
