Track your peptide protocol. Free.
Log every dose, rotate injection sites, watch estimated compound levels, and keep your full history in one place. No app download, no subscription, no data lock-in — export everything anytime. Works on your phone.
Dose logging & schedules
A daily checklist with one-tap logging, plus a month calendar of your doses and upcoming schedule. Prefilled from our 61 protocol pages.
Injection-site rotation
Eight-site rotation with the next site suggested automatically, so you never double up on one spot.
Reconstitution math built in
Enter your vial and bac water once — every logged dose shows the exact U-100 syringe units.
Vial countdown
Track the vial you are drawing from: doses remaining, the 28-day window, and a reorder heads-up before it runs dry.
Estimated levels curve
A half-life-based curve of estimated relative compound levels across your recent doses.
Weight tracking
Quick weigh-ins with a trend chart alongside your dosing history.
Private & exportable
Your log belongs to you. Download the full JSON export or delete your account and everything with it, anytime.

Recent activity
Filled dots are logged doses. Rings are the projected schedule. Tap a day to see or edit its entries.
Estimated compound levels
Relative levels modelled from the published half-life and your logged doses. Illustrative only — not a measured value, not medical advice.
Log doses on a compound with a known half-life to see the estimated-levels curve.
Weight
Quick weigh-ins alongside your protocol. Units are whatever you weigh in — just be consistent.
Symptoms & side effects
Log anything notable with a 1 to 5 severity. Entries land in your JSON export and the printable summary, right next to the dose history.
