Sema + Reta… has anyone tried it? At what dosages? Effects?

Someone here is probably doing it, though the reta plus tirz stack gets used more often for the same goal. Opinions on stacking GLP peptides vary, mainly over limited research on long-term biological safety rather than current side effects. One view is that reta's different impact on glucose could partly reduce the other compound's effectiveness. Another is to watch total receptor stimulation when overlapping agonists. A frequent workaround is stacking cagrilintide instead since it hits a separate pathway yet still cuts food noise. That said, I've run the reta plus tirz combo briefly just for the food-noise reduction and felt fine with no bad effects, though I'm still adjusting my approach as I learn more. Everyone responds differently.

Tirz looks strongest for appetite control, so switching might be the smarter move. There's some case for adding a little reta to a tirz plan to improve outcomes, but faster weight loss often means more muscle loss. You can offset that with diet and lifting, yet if you're already doing those things you probably don't need the extra push.

My doctor has me on 2.4 mg semaglutide through Wegovy. I've hit a standstill and haven't dropped weight since last July, maybe five pounds total at most. I'm considering adding 0.25 or 0.5 mg retatrutide starting April 13. I'll take the usual Wegovy shot on Monday and begin retatrutide on Thursday. Hope the experiment goes okay.

I've been stacking 0.125 mg sema twice a week with 9 mg reta twice a week for a bit over five weeks on staggered days. The first 0.25 mg dose hit harder than expected and left me feeling off. Down 17 pounds so far, though some came from dropping creatine and the water weight that followed.

Sema and reta work well together. Reta is a fairly weak GLP-1 agonist while sema is purely a GLP agonist, so it fills that gap. I'm cautious about tirz because both reta and tirz are strong GIP agonists. Currently using 2.4 mg sema and 4 mg reta; higher reta doses start hurting my sleep quality.

Using 1.2 mg sema and 8 mg reta weekly. Progress is slow so I've started lowering doses, now at 1.2 mg sema and 4 mg reta. Planning to taper reta off over the next twelve weeks, stay on sema another six weeks, then check if weight returns. If it stays off I'll reduce sema by 0.2 mg every four weeks to find a maintenance level.
