The standard retatrutide protocol crashes you.
Retadose doesn't.

Every dose you inject stacks on top of the last. Standard titration protocols were designed for population-level trials — they have no mechanism to find or hold your therapeutic window. Retadose models your real-time retatrutide level and estimates a suggested dose to keep you there.

"I built this because I was that person. 1 mg every four days and I couldn't focus, couldn't eat, missed workouts. The dose hadn't changed. My level had been silently stacking for weeks.

Retatrutide isn't supposed to crash you — it's supposed to let you train, eat well, and lose fat without sacrificing muscle. That's what finding your level actually means."

Why standard retatrutide dosing fails individuals

01

Doses stack invisibly

Retatrutide's half-life is ~6 days. Prior doses are still active when you inject the next one. Without visibility into total level, you're dosing blind.

02

Standard protocols can't personalize

The titration schedule was designed to escalate entire trial populations. It has no mechanism to identify — or hold — your individual therapeutic window.

03

The goal is not maximum suppression

You should still eat. You should still train. Retadose targets the level where appetite is controlled and energy and performance are preserved.
