From Reta back to Mounjaro

I tried Retaitride but don’t like it. Last injected 2.5mg 4 days ago. How long do I need to wait until I go back on the MJ starting dose?

As its not licensed are you part of the clinical trial? If so you need to talk to them.

Ask your prescriber, although no one could be legitimately prescribing to you unless you’re on a clinical trial for Retatrutide. In which case they probably won’t want you stopping!

You can do it now. Some people stack them together. Depends how strong it is for you. Might get a bit much so maybe wait a few more days x

This is dangerous and stupid advice from MymateDave.

Whatever you are injecting, genuine retatrutide is being studied in its phase 3 clinical trials as a once a week injection. That would suggest that it is similar to Mounjaro and has a half life of around 7 days. That would then mean it would take 30 to 40 days for all of it to be out of someone's system after the last injection. I would wait at least 30 days for whatever you've been taking to hopefully be out of your system before taking a legitimate prescription GLP1 like Mounjaro. (I hope that the Mounjaro you plan to take is being legitimately prescribed)

Well Reta is not real so why are you asking here?

SilenceInside · 02/11/2026 17:31

Did you not get on with the Wegovy tablets that you were trying at the end of September @cknfused ?

I think you would benefit from booking a consultation with a supportive provider and speaking to either an independent prescriber or preferably a Dr and being honest with them.

Moving from MJ, to Wegovy pills to trying out illegal unknown drugs all in the space of 6 weeks is erratic and reckless. Seek some professional help for both your safety and to get advice and a plan to move forward.

Please, if switching back to and buying Mounjaro again buy from a registered pharmacy.

You’re not on Reta, you must be buying fake product from China, via a hairdresser, tik tok or a gym, or online.

I would probably give it a good break given it’s unlikely you know what you have even been using.

Who knows what it was in the injection that didn’t suit the OP!

You’d need a wash out period, stacking them when you don’t know exactly what you e taken is likely a recipe for bad side effects. I’d give your body a good break for a few weeks
