Alternating cagrilintide and eloralintide?

Summary

Does switching between cagrilintide and eloralintide help when appetite suppression fades while using tirzepatide?

One user reports appetite suppression from cagrilintide fading after a couple weeks even after breaks, and wonders if eloralintide would hold up better during those periods. Others note both act on similar pathways so cross-tolerance is possible, though one person found eloralintide more consistent, longer-acting, and tolerable at higher doses without the same stability issues. Limited long-term data exists for cagrilintide at higher doses, and alternating is viewed as potentially unnecessary.

What this discussion establishesWhere people disagree

Whether quick tolerance to cagrilintide is common or unusual, and whether alternating agents is worthwhile versus sticking with one.

Still open

How common rapid tolerance to cagrilintide actually is and whether eloralintide would avoid the same pattern for this user.

Nothing here is advice.

While combining tirzepatide with cagrilintide, the cagrilintide effect fades after a few weeks so I pause it and resume later. Would swapping in eloralintide during those pauses be reasonable?

Since they work through the same route, it might not help much either.

I have not come across reports of cagrilintide working then fading that fast. What amounts of tirzepatide and cagrilintide are you using, how much weight came off and over what timeframe, plus starting weight, goal, age, height? How long did each cagrilintide run last and how long were the breaks? The only quick tolerance I have seen mentioned is for GI effects with GLP-1s, not appetite control, and nothing in studies points to cagrilintide losing effect that way. Eloralintide is stronger for weight loss and milder on sides, so trying it is low risk, but cycling different ones does not seem ideal. If tolerance to cagrilintide develops oddly fast, the same could occur with eloralintide. Does this not happen with tirzepatide for you?

What exactly do you mean when you say it stops working?

I am in maintenance now after starting at 195, aiming for 140, currently 139, height 5'5", 68-year-old male. Tirzepatide began in January, cagrilintide in April. Only side effect has been fatigue. Current weekly amounts are 15 mg tirzepatide split and 3.5 mg cagrilintide. I added cagrilintide to get steadier appetite control since tirzepatide alone is inconsistent. Started cagrilintide at 0.25 mg and raised it whenever suppression faded, but instead of continuing to increase I paused. After three weeks off I restarted and it worked for a couple weeks before fading again. Eloralintide has good reports and I hoped it would stay effective longer than cagrilintide.

Cagrilintide loses effect much sooner than eloralintide. I have used both and eloralintide is clearly superior. You can also dose eloralintide higher, with studies going up to 9 mg without problems. I switched to it at 2 mg and it works very well. I will not return to cagrilintide. It helped me move past stalls and avoids stimulating calcitonin, which has no role in weight loss anyway. Less off-target binding seems preferable. Eloralintide is also more stable and lacks the same tendency to form fibrils, so no need for acetic acid. Its longer half-life means greater accumulation and higher steady-state levels at the same dose. The only drawbacks are cost and supply. If you can manage those, there is no reason to go back.

I do not have better suggestions than testing eloralintide yourself. From studies and many reports, patterns with common GLP drugs are fairly predictable, but far less information exists for cagrilintide. Most users add small amounts to tirzepatide or retatrutide at their max doses while still trying to lose more weight, and not many run cagrilintide at higher levels. Longer-term follow-up data on cagrilintide or cagrisema does not seem widely available. Nothing rules out tolerance developing with cagrilintide even if it rarely occurs with GLP drugs, or your reaction could simply be atypical. Another route is increasing tirzepatide further or adding some retatrutide, depending on how 15 mg tirzepatide affects you. I began these drugs after most of the weight was already gone to manage ongoing hunger, and 15 mg tirzepatide handled that reasonably well.
