Considering raising Reta to 20mg after long stall

Summary

Has anyone gone above 15 mg reta to break a stall and what alternatives like elora or cag are people considering

The original poster started GLP-1s in 2023, reached 220 with sema then stalled, added reta in 2026 and is now at 15 mg reta plus low sema at 191 lbs with another stall, still wanting to drop another 11 lbs. Several users mention trying elora or cag before increasing reta further, with some noting receptor differences and side-effect profiles. One user references limited high-dose reta experiences from others. No one reports personal results above 15 mg.

What this discussion establishesWhere people disagree

Users differ on whether elora or cag is preferable due to tolerability and exact receptor targeting

Still open

Whether increasing reta past 15 mg will break the stall or what side effects might appear

Nothing here is advice.

Started GLP-1s in spring of 2023. Used sema to drop from 336 to 220 but stalled for months in 2025. Added reta early 2026. Now at 15 mg reta and 1.33 mg sema, weight stuck at 191 again. Goal is at least 180 since still more than 25 lbs above the upper BMI recommendation. Might try elora for stacking. How many have gone over 15 mg on reta?

I cannot answer your question since I'm on a low dose. But have you considered calguritide or maz in your stack? Those hit a different receptor.

Do you mean cagrilintide? Mazdutide is GLP and GCG, the same receptors as reta without the GIP part.

You're right. I'm super tired. Going to bed.

Not my own experience but I've seen reports of quite a few people breaking a stall with elora. I'd try that or cag before going up to 20 mg of reta.

My initial belief was that the two compounds engaged matching receptor sites, though the first one felt far easier to handle overall.

When I elevated the level too far my rodent saw its glucose reading fall. Now I'm pondering those two substances.

Cag seems to interact with several amylin receptors along with calcitonin whereas Elora stays specific to just the AMY3 subtype.

NorthFenwick56archiveOct 31

For some time I thought about cagri yet the exhaustion it brings was something I wanted to avoid completely. I planned to add tirz to my reta but later shifted my plans. About ten days ago I began elora at a small amount of half a milligram. Sema counted as another possibility too.

If the original poster plans to reach twenty milligrams of reta, I'd really like to hear the input from someone who has already gone there. Very few have attempted such a large amount with reta, but this individual did and survived to recount it.
👍 👍 😎

Back in August when I reached 200 pounds I lowered my weekly amount from 20 mg down to 8 mg and appetite stayed under control. I raised it again to finish the remaining weight. My sleep now feels at least as solid as right after that reduction and noticeably better than it was in September. Bowel movements have been more consistently comfortable than I can remember in quite a while. There could be longer-term questions at these amounts but nothing has appeared for me and no studies indicate problems. Older work suggested reta might allow the most headroom on dosing before issues arise, though that came before phase 3 results. Bloodwork will reveal whether anything stands out. A couple more months and I’ll repeat the micronutrient panel and fatty acid balance test. A few values were low or borderline earlier and the balance test looked off, which pointed to fish oil even though I had already stopped taking it months before.

This sits a single milligram off what proved fatal for the other fellow.

Before moving into untested higher amounts, have you tried adding extra exercise for one week or cutting another 100 to 200 calories daily for a week? Those steps have helped me move past plateaus. Biology also shifts once you reach the final 20 pounds. What worked earlier can stop working. Hunger becomes tougher to manage at both conscious and subconscious levels. This can look like a long stall. If you are not carefully watching intake you might be adding calories without noticing and that can create the stall.

I overlooked the earlier discussion. That's surprising. My budget simply couldn't cover getting that combination every month.

You have already lost 43 percent of your starting weight, so well done. Almost no real research exists yet on how to handle losing more than 30 percent. Next steps would probably depend on current side effects. You have not mentioned any problems, so going higher with reta makes sense if nothing is bothering you. Just to be cautious it might be worth checking that heart rate is not elevated, since high-dose data is still missing. Elora could be the stronger addition because it works on different receptors and appeared to give extra loss even on top of 15 mg tirz, around another 12 percent. Higher reta amounts are more likely to hit diminishing returns. Cagri did not add as much extra loss when paired with semaglutide. It is a long process and you may need to test several approaches.

Many unknowns remain around these situations and the biggest one for me right now concerns how much time this particular pause has already taken up. Anything shorter than roughly a month and a half sometimes clears without extra effort yet that does not lessen the worry when earlier pauses have already happened. Food choices and movement still matter a great deal even while these medicines are in use and simply raising the subject tends to annoy folks who feel they already tried both without results. Still the medicines appear to fix an important feedback loop that influences how the body handles energy and resists insulin a problem that pushes fat storage while stopping the release of stored fat for fuel. In the past I have checked my own intake numbers and stepped up activity for a short period as a way to test whether the medicines now allow those steps to produce movement where nothing happened before. It would be good if the original poster could meet with a doctor focused on metabolic issues and if possible get full blood work plus a body composition scan since that scan shows exactly where fat sits and whether the pattern calls for one approach or another. I also track my own readings with a multi electrode home scale even though it is not exact because daily fluid changes can swing the numbers wildly so I only watch the pattern across weeks instead of any single reading. The extra suggestions about recalculating daily burn rates checking protein while lifting and looking at sleep and stress levels also line up with what I have noticed in my own case.
