Track your tirzepatide journey.
Tirzepatide powers both Mounjaro and Zepbound — the most powerful GLP-1 medications available. Phaze helps you preserve muscle, build lasting habits, and turn rapid weight loss into permanent transformation.
Built for tirzepatide users.
Every feature designed for tirzepatide's faster weight loss and higher protein needs.
Protein-First Tracking
Tirzepatide users lose weight faster than any other GLP-1, making muscle preservation critical. Phaze targets 0.8-1.0g protein per pound with smart daily tracking and AI meal photos.
Rapid-Loss Muscle Shield
Tirzepatide's dual-hormone mechanism drives aggressive weight loss. Phaze's protein tracking and movement habits help you preserve the lean mass that keeps your metabolism strong.
Habit Streaks That Stick
Build the hydration, movement, and nutrition habits during tirzepatide treatment that become your permanent maintenance system after medication.
Progress Photos & Milestones
Tirzepatide transformations can be dramatic. Capture every stage with guided comparison photos and shareable milestone cards — medication info stays completely hidden.
Phaze Progression System
Personalized stages that match tirzepatide's rapid results — adapting your goals as your body and habits evolve through dose escalation and beyond.

Tirzepatide medications we support.
Mounjaro and Zepbound share the same active ingredient — tirzepatide. Phaze supports both with features tailored to each.
Mounjaro
tirzepatide · Eli Lilly
The first dual GIP/GLP-1 receptor agonist. Phaze tracks your protein, builds habits through dose escalation, and prepares you for life after Mounjaro.
Learn moreZepbound
tirzepatide · Eli Lilly
FDA-approved specifically for chronic weight management. Phaze helps Zepbound users preserve muscle during rapid loss with aggressive protein tracking and habit building.

Build Habits During Medication
While tirzepatide handles appetite with its dual-action mechanism, Phaze builds the protein, hydration, and movement habits your body needs long-term.
Track What Matters
Forget calorie counting. Phaze focuses on the metrics that predict lasting success — protein intake, daily streaks, and body composition.
Maintain After Medication
When you taper off tirzepatide, the habits you built become your maintenance system. That's the V-to-L difference.
Tirzepatide + Phaze FAQ
Yes! Mounjaro and Zepbound are both tirzepatide — the same dual-action molecule. Mounjaro is prescribed for type 2 diabetes and weight management, while Zepbound is FDA-approved specifically for weight loss. Phaze is built for all tirzepatide users regardless of brand.
Tirzepatide produces faster, more aggressive weight loss than semaglutide because it targets both GIP and GLP-1 receptors. This means more muscle is at risk during rapid loss. Phaze sets higher protein targets (0.8-1.0g per pound) and tracks every gram to help you preserve lean mass.
Tirzepatide (Mounjaro/Zepbound) is a dual-action GIP/GLP-1 receptor agonist, while semaglutide (Ozempic/Wegovy) targets only GLP-1. Clinical trials show tirzepatide produces greater average weight loss — up to 22.5% body weight. Phaze accounts for this faster trajectory in its habit-building approach.
Absolutely. As you titrate up on tirzepatide, your appetite and side effects change at each dose level. Phaze adapts your goals, celebrates consistency through every adjustment, and builds the habits that stay with you regardless of what dose you're on.
Studies show significant weight regain is common after stopping GLP-1 medications. That's why Phaze exists — the V-to-L system builds sustainable habits during medication (protein, hydration, movement, consistency) so they become your permanent maintenance system after you stop.
