Retatrutide + Phaze FAQ

Retatrutide is a next-generation triple-agonist from Eli Lilly that targets GIP, GLP-1, and glucagon receptors simultaneously. Clinical trials have shown up to 24% body weight loss, more than any other weight loss medication. Phaze is ready to support your retatrutide journey.

While tirzepatide (Mounjaro/Zepbound) targets two receptors (GIP + GLP-1), retatrutide targets three (GIP + GLP-1 + glucagon). The glucagon component increases energy expenditure and fat burning, producing greater weight loss in trials. Phaze tracks your journey on either medication.

Given retatrutide's aggressive weight loss, 0.8–1.2g of protein per pound of body weight is recommended to preserve lean muscle mass. Phaze calculates your personal target and makes hitting it effortless with AI meal scanning.

That's exactly what Phaze is designed for. The V-to-L system builds sustainable habits during medication so you maintain your results after stopping. This is critical with retatrutide given its powerful effects.

Yes! Core features are free forever: dose tracking, nutrition logging, streaks, milestones, and Apple Health sync. Premium ($4.99/month or $34.99/year) adds AI meal scanning, unlimited photos, and more.

Retatrutide is investigational, your trial protocol or prescriber will specify labs. Phaze tracks every biomarker your doctor orders. Always follow your provider's guidance.

The faster the weight loss, the higher the lean mass risk. DEXA import in Phaze v3.1 makes it possible to monitor body fat % and lean mass quarter by quarter.
