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."
The problem
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.
The titration schedule was designed to escalate entire trial populations. It has no mechanism to identify — or hold — your individual therapeutic window.
You should still eat. You should still train. Retadose targets the level where appetite is controlled and energy and performance are preserved.
How it works
Date, time, amount in mg. That's it.
Retadose models your estimated retatrutide concentration using published PK constants from Coskun et al. 2022.
Tell us when you feel optimal: appetite controlled, sleep good, energy up. That's your target level.
Retadose estimates what to inject next — and when — to return to your window.
Built for people on compounded retatrutide who take their protocol seriously. Log your doses, track your level, and bring a complete export to your next prescriber visit.
