Switched from tirz to Reta then back to tirz

Summary

How to restart weight loss on tirzepatide after switching away and returning, especially with a recent stall or gain?

The original poster lost steadily on tirz then reta but regained weight after stopping and has now gained more since restarting tirz. Others report stalls eventually break with time, stacking multiple peptides, changing injection frequency, or adding refeeds. Several note that going off and back on these meds can reduce their effectiveness, so higher amounts may be needed the second time around. Practical suggestions include tracking intake strictly and combining with strength or cardio work.

What this discussion establishesWhere people disagree

Some prefer pushing tirz higher while others favor adding different peptides like reta or survo for better results instead of dose increases alone.

Still open

Whether the recent weight gain on restarted tirz is temporary or signals reduced response long-term.

Nothing here is advice.

I began using these meds in September 2024 at 232 pounds and reached 174 by May 2025 on tirz. I switched to reta for variety and dropped another 16 pounds down to 157 by February 2026, but have since climbed back to 175. I returned to tirz three weeks ago yet have gained six more pounds. I wonder if the body can become less responsive over time. I am aiming for 140-145 and would like to hear from others who have broken through stalls.

Stalls always end for me no matter what. Stacking different ones in the same week works, as does moving up faster or splitting doses or switching to every other day. Those approaches have all paid off eventually.

You dropped weight on tirz, tried reta next, then paused everything and regained around twenty pounds, which is typical when stopping. Going off and restarting these meds often makes them work less well the next time, based on what people report and one study. Maybe the current amount is not high enough to match that reduced response.

From an earlier post by the original poster before the switch to reta, continuing with tirz would mean stacking. Some reach twenty plus milligrams successfully, though returns may be smaller than with stacking. Trying cagri once before was mentioned, and elora is noted as a newer but more expensive option.

Why focus on diminishing returns? If the dose is doubled and another five percent comes off, that is still progress unless side effects become the problem.

Use the loseit app, set it for sedentary activity, log every item, and skip adding back exercise calories.

A recent thread covers similar ground with ideas like trying reta, adding cardio, or accepting the plateau. One person started compounded tirz last Thanksgiving at 245 and reached 181 but has stayed there for four weeks after an earlier stall at 187.

On tirz dosing I would lean toward wanting more glucagon activity like a reta user. The thread referenced earlier makes a similar point.

I continue to rely on my tirz and survo combination after a full year.

↳ replying to @IronThistle42

I recently obtained some survo since reta does not suit me well. What dosing schedule do you follow?

That is basic advice. Next step would be suggesting walks and heavy lifting I suppose.

My schedule has been 7.5 of tirz on Friday and 2 of survo on Sunday for eleven months. It holds weight at goal, keeps appetite and food intake steady, and maintains energy without feeling deprived. I pair it with strength and cardio three to five times weekly, though that routine has loosened lately. Overall I feel better and less obsessive than during the initial fifty-plus pound loss phase.

When I hit a stall at a dose I switch to every six days instead of seven and can usually continue losing for another eight to twelve weeks without raising it. Eating more for a couple days also helps when restriction has been too tight; a refeed gets things moving again for me.

Curious how rough the tiredness gets for most folks on tirz. Thinking about adding it to reta but really don't want to feel wiped out all the time and leaning on energy drinks nonstop.

One way to look at the tiredness is it's your body doing some healing on top of the lower calories and getting used to the GLP plus its stomach effects. Either way adding tirz to reta tends to work like adding it to sema, giving a nice lift if the sides stay manageable.

Totally wiped out for a full day right after a bigger dose shot, then back to normal. That passed for both me and the Bride after around four months.

Only three weeks back on means it's still early, and the first month often shows scale shifts from water and glycogen either direction so don't read much into it yet. Putting weight back on after stopping or switching is pretty typical, so it doesn't mean anything's wrong on your end. Honest tracking for a bit plus keeping protein high will give clearer info than looking for new stacks, and check any dose tweaks with the prescriber. It's the usual boring advice but sticking with it tends to pay off.
