Penta agonist weight loss stack? Tirz x Reta x Cagri

6 replies4 peopleJul 3, 2026☆ Follow
Summary

Has anyone tried stacking tirzepatide, retatrutide, and cagrilintide together for weight loss, and does it help break plateaus?

A few users report running the triple stack on a staggered every-other-day schedule after stalling on tirzepatide alone. One person lost 55 lb over seven months but needed to raise all three compounds before seeing movement again, while another saw no appetite effect from cagrilintide at all. Side effects such as skin sensitivity appeared when doses were increased. Some participants question whether the overlapping GLP-1 and GIP activity is useful.

What this discussion establishesWhere people disagree

Whether the triple combination provides meaningful benefit over dual stacks or simply adds side-effect risk.

Still open

Whether recent water retention from other compounds is masking ongoing fat loss in the stalled user.

Nothing here is advice.

Has anyone tried running this combination? I'm already using retatrutide with tirzepatide and was thinking of adding a cagrilintide shot mid-week to strengthen hunger control, since my cravings usually ramp up later in the week. The idea is mainly to reach five receptors total.

I'm doing exactly that on a six-day schedule with a shot every two days. I started it to get past a stall, first on tirzepatide, then added cagrilintide, then retatrutide. Cagrilintide hasn't affected me the way many others describe. I went up to 10 mg tirzepatide every six days over four months and began getting tinnitus and prickly skin, so I stopped raising that dose. I had already dropped 40 lb by then, but hit a month-long plateau. Adding 500 mcg cagrilintide every six days changed nothing. Adding 1 mg retatrutide every six days also did little. Raising both to 1 mg cagrilintide and 2 mg retatrutide still barely moved the scale. Only when I reached 2 mg cagrilintide and 4 mg retatrutide alongside 12 mg tirzepatide did the loss restart. The first two nights after that increase the skin sensitivity was bad enough that I considered stopping everything. It has eased a bit since.

I'm also thinking about adding cagrilintide for hunger control. Tirzepatide for eight weeks gave me nothing, so I switched to retatrutide. Still nothing, though it's only been six weeks. Neither one has quieted the food noise and it's frustrating. I'm trying to stay patient but it's really hard.

Wouldn't tirzepatide and retatrutide overlap on some of the same receptors? It looks like you're doubling up on GLP-1 and GIP without much point. Why not just run retatrutide with cagrilintide and drop the tirzepatide?

Some people get reactions at higher retatrutide doses. I was the one reacting to higher tirzepatide instead. It worked very well until 10 mg every six days started causing allodynia and tinnitus, which is why I brought in retatrutide. When I raised everything the skin sensitivity got so intense I almost quit the whole thing. After a few days it settled back to a milder level. Two weeks later, though, the stall appears to have returned even at 12 mg tirzepatide, 4 mg retatrutide, and 2 mg cagrilintide. An AI analysis suggested the water retention from restarting BPC and TB500 might be canceling out the fat loss for now, so I'm waiting to see if things stabilize.

How long has the stall lasted, if you don't mind sharing? Did adding cagrilintide seem to help at all?

The tirzepatide stall lasted about a month. After adding cagrilintide there was still no movement, then retatrutide went in a month later. I lost five more pounds before stalling again. Three weeks after that I raised the doses and dropped two more. Even at 2 mg cagrilintide every six days it does nothing for me—no loss, no appetite change, no sides. Even if the scale stays put from here, the 55 lb total loss in seven months has been worth it, almost all from tirzepatide alone. If the water-retention theory is right, results should show once things settle or during the next break from the other compounds. Patience isn't my strong point.
