Built for the way you dose. See your estimated medication levels, rotate injection sites, and never miss a shot. For GLP-1, Peptides, TRT, HRT & more.
Injex is the precision tracker for everyone who doses: GLP-1, TRT, HRT, prescribed peptide therapy, and every self-injection protocol in between. Log a shot in seconds, see your estimated medication levels between doses, and always know which site is next.
Your protocol is data. Injex treats it that way.
WHY INJEX
• Estimated level curves: see how your medication rises and falls between doses, modeled from your real schedule and published half-life data.
• Smart site rotation: a color-coded body map shows which sites are ready, healing, or recently used, and suggests the most-rested one next.
• Everything in one place: doses, sites, side effects, supplies, and progress. No spreadsheets, no notes app.
YOUR LEVELS, VISUALIZED
Watch your estimated levels build toward steady state, see when they peak, and know when they're wearing off. Built on published pharmacokinetic data with honest confidence labels, so you always know what you're looking at.
NEVER MISS A DOSE
Schedules that match how you actually dose: weekly, daily, every other day, specific weekdays, or your own custom cadence. Time-sensitive reminders land right at your dose time, snooze when life happens, and your streak doesn't break just because you logged late.
ROTATE LIKE A PRO
Rotation protects your tissue and your absorption. Injex tracks every site you use, warns you when one is overworked, and pre-selects the most-rested spot: abdomen, thigh, glute, or deltoid.
TRACK THE WHOLE PICTURE
• Side effects, auto-correlated to hours after your dose
• Mood and pain with every log
• Vials, pens, syringes, and needles, with days-of-supply math and refill alerts
• Titration steps, with a prompt when it's time to advance
SHARE IT WITH YOUR DOCTOR
Export a clean, clinician-ready PDF covering your last 90 days of doses, adherence, and side effects, or your complete history as CSV. Your data is yours.
PRIVATE BY DESIGN

Injex is a tracking and analytics tool. It does not provide medical advice, diagnosis, or treatment, and it never recommends doses. Always consult your physician before changing your protocol.
