Tirz not working anymore

Summary

Tirzepatide stopped curbing cravings and hunger returned on 3 mg with cagrilintide, what dose or schedule change next?

Users report that 3 mg tirzepatide is still below a therapeutic level for many and recommend moving to 5 mg weekly, then 7.5 mg if needed, while keeping the 0.5 mg cagrilintide. Slow titration based on minimum effective dose is debated against faster schedules; some argue the latter reaches the effectiveness ceiling sooner while others see no evidence of receptor burnout from speed. Daily dosing is rejected in favor of weekly or every-five-days spacing, with total weekly amount never exceeding 15 mg.

What this discussion establishesWhere people disagree

Whether slow titration and dietary changes can meaningfully extend the period of effectiveness compared with standard trial schedules

Still open

How long any given dose remains effective once weight loss has plateaued and whether cycling compounds resets sensitivity

Nothing here is advice.

Hi everyone, I've been on Tirzepatide for some time and added Cagri about half a year ago. My current weekly amounts are 3 mg of the first and 0.5 mg of the second. Lately it seems less effective; hunger is down but cravings returned and I'm eating more. Any suggestions on next steps?

The medication is still active but your body is increasing hunger signals again. That is why obesity is viewed as a chronic relapsing condition. The straightforward move is to raise the dose.

This is pretty frustrating. How big of an increase makes sense? Would switching to daily shots of 5 mg be reasonable?

SharpCinder28archiveMay 20

Typical steps are 2.5 mg at a time no matter how the weekly total is split. Daily dosing is unusual compared with every five days.

Next step is 5 mg weekly; if that loses effect after a few months move to 7.5 mg. Leave at least three days between any injections and never dose daily.

Any reason the dose hasn't been raised already? If side effects are manageable then titrating up is the usual next move. You've been on it since January 2025 so you may be nearing the practical limits for further loss. Daily shots probably won't help; if hunger returns toward the end of the week, increasing the amount first is better.

CopperSignal27archiveMay 20

Moving from 3 mg weekly to 3 mg daily would be a seven-fold jump and 21 mg per week, well above usual maximums. From 5 mg daily that would reach 35 mg weekly. Either change carries a high chance of severe nausea, vomiting and dehydration requiring hospital care. Total weekly amount must stay within the 15 mg cap and increases should stay at 2.5 mg steps following the standard four-week intervals at each level.

BrightQuill59archiveMay 20

Thanks for the input. I meant every five days instead of weekly; the translator mixed that up. I stayed at 2.5 mg while it worked and only added 0.5 mg when progress slowed. I'll try 5 mg next week. Should I drop the Cagri or keep the 0.5 mg?

Is there really a hard limit? The idea of an effectiveness window seems overstated. Quick titration to the top dose lets the body adjust faster, but staying at the lowest effective amount might avoid that. Trial schedules were built to show fast results for approval, not long-term optimization. Slower steps plus lower-calorie food and resistance training could keep results going longer at lower doses.

PatientHarbour23archiveMay 20

I raise the dose very gradually, only a unit or two at a time. From 3 mg weekly that would mean trying 3.25 mg for a few weeks first.

There is still an effectiveness window and the drug eventually stops working at any dose. A slow climb does not leapfrog faster ones because of receptor burnout; no data supports that idea. In the trials the 15 mg group still did best despite the quickest ramp. People with more weight to lose also benefited more from faster increases.

No clear need to stop or lower the cagrilintide, especially with a trial now testing the combination. How long have you been at 3 mg tirzepatide and at 0.5 mg cagrilintide?

ClearHarbour22archiveMay 20

Would switching to sema or reta for a couple of months reset sensitivity to tirzepatide? Keep a kit of the other compound on hand for occasional rotation.

3 mg is not viewed as a therapeutic dose. 5 mg is the level considered therapeutic for both obesity and diabetes.

GreenMeadow54archiveMay 20

That does not contradict the point. The trials had no dietary changes and held doses steady. With diet adjustments and minimum-effective-dose titration the window should stretch further. You cannot compare med-only results to results that also include lower calorie density food.

WarmMeadow92archiveMay 20

Trial participants received diet counseling and regular measurements. They were motivated enough to join a study, so they had more support than most people using the medication outside trials.

GreenMeadow54archiveMay 20

The trials prioritize quick approval and headlines, not optimal long-term use. They push everyone up on a fixed schedule. Future studies that tie dose increases to actual weight loss and diet changes will probably show slower moves and longer effectiveness. The body adapts to any fixed dose over time, but that does not mean higher doses will stop working entirely.

Healthy debate is fine. My own results come from needing to lose over 100 lb. Slow low dosing would have left me far from goal. A family member lost 50 lb staying at 2 mg and is near goal after nine months, but she had far less to lose. For substantial weight loss the faster path made sense for me; I have now lost 115 lb.

LevelWillow41archiveMay 20

Rate of increase is very individual. Trials used aggressive ramps on high-need patients to show maximum short-term effect. Other approaches that value comfort and steady compliance will need different schedules.

CopperSignal27archiveMay 21

All GLP studies show weight loss slowing toward zero after roughly a year. Titration speed effect is unclear; it may simply reflect time to reach steady state. After a year on a lower dose an increase might still help, though perhaps less than an earlier increase. Metabolic adaptation from long-term lower intake also reduces daily energy use by up to 20 percent, making further loss harder regardless of dose.

SlowSignal40archiveMay 21
↳ replying to @WarmMeadow92

That is straightforward advice. 3 mg still looks low; moving toward 5 mg with careful steps or adding a lower dose of reta could be options depending on how much more weight remains.

SharpCinder28archiveMay 21

I reached 5 mg by the second week on a prescribed aggressive schedule. Some people respond strongly to low doses while others need much higher amounts just to hold weight. Most fall in between, and a few see almost no effect at any dose.

PatientFenwick55archiveMay 23

I would not titrate up. After stopping for six weeks for a procedure, restarting felt extremely strong even at a low dose. Trying a break and then returning at starter level might restore response. I lost steadily on 2.5 then 5 then 7.5 mg but stalled at 10 mg; stretching intervals to 10-14 days helped again. I am now back at 7.5 mg and still losing.

LevelBramble14archiveMay 23

Move to 5 mg tirzepatide and then 7.5 mg if results are still missing. At those higher amounts the cagrilintide will probably not be needed.

Is the hunger increase steady throughout the week or mainly right before the next shot?

RustTimber85archiveMay 24
↳ replying to @BrightQuill59 (opening post)

I have always used a titration flow chart to stay at the lowest effective amount.

BlueSignal76archiveMay 24

Calling 3 mg ineffective is premature; there is still room to go up to five times that amount. Receptors adapt to a given level, which is exactly why titration is possible.

What were your starting and goal weights?

Thanks for the exchange; it has been very useful.
