Ret or cag?

Summary

For someone on tirzepatide whose weight loss has slowed, is stacking cagrilintide or retatrutide the better next step?

The thread shows a patient at 10 mg tirzepatide every six days with slowed loss and no side effects. Participants note cagrilintide can add appetite suppression via a different pathway and is often started very low, while retatrutide is suggested as a possible switch or add-on. Some prefer waiting for eloralintide due to reported better efficacy and tolerability, though others see current cagrilintide as the more established grey option. Slow titration and monitoring remain the common advice.

What this discussion establishesWhere people disagree

Whether to introduce cagrilintide now or wait for eloralintide, and whether the fibril-stability concern with cagrilintide is meaningful.

Still open

How much additional loss the stack will produce for this specific patient and the safest long-term combination.

Nothing here is advice.

My spouse recently started a medication for weight loss. He deals with severe obesity. The physician suggested combining it with another option similar to a certain compound. What choice might suit him better?

I'd like some extra specifics on the amount being taken now along with the injection schedule. Has body mass dropped at all and what reactions have appeared?

This one targets amylin receptors rather than the GLP-1 or GIP or glucagon ones, allowing it to be combined rather than used solo. It goes together nicely with sema, tirz, and reta. Cutting food noise is what it mainly does, even if tirz currently leads among the GLP-1 types for that effect. Stacking isn't ruled out because of the separate mechanism, yet the reason for doing so puzzles me if max levels aren't hit yet. The reta one stands strong alone, still, prior levels from another GLP-1 might require adding extras to ease unwanted effects or focus on particular aims. In my case, I combined reta with cag since effects became too much beyond a threshold and the noise around eating disappeared. That was until I stopped ahead of an operation. Starting again, I'll try reta by itself initially and monitor after a fortnight break. How has the path gone for him up to now?

I've mostly kept quiet here but this discussion is heavily promoting that newer cagrilintide variant along with endorsements for the seller who indicated availability by the close of the month. A physician could speed up dose increases on tirzepatide if someone hasn't hit the top approved amount yet. Adding the triple agonist now might also make sense because gains taper off past roughly ten milligrams of tirzepatide. My own approach will combine any GLP agonist or mix of them, possibly moving to just the triple agonist down the line, plus the new compound once it shows up.

I take ten milligrams of tirzepatide. My weight reduction has become much slower lately. I inject on a schedule of every six days and experience no negative effects. My doctor supports me getting the gray market product and provides helpful recommendations.

That's not accurate at all. This amounted to nothing beyond a basic inquiry. Everyone jumps straight to negative assumptions far too fast. I made zero effort to promote cag and simply wanted to learn about the better option.

Luck is definitely with him since zero unwanted reactions have shown up so far. The current ten milligram level of that medication suits him fine and I see no reason to change anything given how set in his ways he tends to be along with the time spent convincing him to try the grey route. He moved the dosage higher pretty quickly and ran into nothing at all.

I've been advocating for elora whenever possible. There's an ongoing study mixing elora with tirz, so it surprises me that cagri is still under discussion for buying a set. I'd hold off on elora myself. At this stage I'd skip cagri purchases altogether, aside from perhaps one small container. Elora works about double as well compared to cagri and comes with fewer unwanted effects. Yet because my partner faces a unique set of risks unlike others in this group, cagri represents a safer option in the unregulated market given its history of use, even though it has stability problems unlike elora involving the unresolved fibrils issue. Therefore which one is truly less risky remains unclear since the unregulated elora lacks real-world checks so far. Similar to cagri, elora allows starting doses measured in micrograms. They both support gradual increases, particularly in combinations.

Ah okay, my error in grasping your point.

After hitting the ten milligram level on the initial compound my scale progress leveled off so I brought in the other substance at a minimal starting amount of point one milligrams and raised it bit by bit each month. It left me with some stomach discomfort yet it reduced hunger pangs. I kept it going for six months then tapered off before picking it back up lately while away from the first compound and trying another instead. To me that second substance does a solid job controlling cravings. I pushed the first one as high as twenty milligrams weekly at one stage but extra loss after the ten milligram point stayed limited. My sense is the first compound supported calorie burn while the second one eases appetite enough to skip meals without effort. I might have it wrong but I prefer slow increases since I had more than a hundred pounds to drop and have now shed ninety three over twenty one months.

It's fine. I sounded a bit extra this time because the price and launch timing for elora are still unclear. Up to now just one seller has shared any plans about future stock. Even beginning with that lone seller, cheaper single bottle sources will probably appear later and let newcomers begin. The combination of those two items plus elora should turn into the top choice eventually. A few reddit comments from people who joined the elora studies:

I'm really enthusiastic regarding this new substance as well, yet the online discussions highlight the present problem. A discussion contains only two replies from half a year earlier and another one dates back more than twelve months with around ten replies. Moreover, because those producers have not created this substance so far, obtaining input from others proves difficult too. I feel way better regarding trying the previous option currently, despite it not seeming quite as strong, yet when combined it should suffice. I've examined the clump concern in detail and consider it probably insignificant.

SharpCinder28archiveApr 21
↳ replying to @WarmMeadow92

I share that view. After a container holding the compound slipped from my grasp, I decided to take advantage by shaking it hard several times in a row. I didn't notice any clumping or similar problems. There was also no persistent bubbling, which you'd anticipate from a sensitive material that's easily damaged, such as growth hormone.

SharpCinder28archiveApr 21

I tend to approach this substance cautiously because its elimination time spans roughly fourteen days, which is double that of the other option and brings both advantages and drawbacks. The injection schedule remains identical at once per week. The benefit here is that the extended duration provides steadier concentrations which improve how well it's tolerated. However, any unwanted effects would persist for an extended duration as well, even if they are fewer compared to the alternative. This one is entering the third stage of trials now.

I started with added cagri 0.1 mg twice a week. Now doing 6 mg tirz, 0.5 cagri on Mondays. 6 mg reta, 0.5 mg cagri on Fridays.

NorthThistle87archiveApr 22

The guy carries serious extra weight yet his physician has no problem with the unofficial version so I wonder why the other compound stays off limits.

WarmSparrow33archiveApr 22
↳ replying to @NorthThistle87

Yeah that happened with him. Slipped my mind to include the detail before. Figured I already covered it. Planned on using cag or ret.

CopperSignal27archiveApr 22

To give a solid reply I would need more background like starting weight current weight how long on the medication and how quickly the pounds are coming off plus age height and general health status. For someone with a bmi over 40 who is using 10 mg every six days without issues the simplest next step with the least chance of fresh problems would be moving up to 15 mg each week. Trying reta or cagri alongside it remains possible yet the main reason to try the higher tirzepatide amount first is avoiding extra side effects. Reta could be less suitable if heart issues exist because it tends to raise heart rate further. Everything hinges on the present situation has the loss slowed or halted is hunger or food thoughts making it hard to stay at a lower calorie level. When the current pace looks steady and sensible there may be no need to go higher since dropping weight too rapidly is not great but reaching a better maintenance level will likely call for the full 15 mg weekly and only after that point would adding other compounds make sense if the scale is still too high.

SharpCinder28archiveApr 22

When someone feels ready to test those options, one container works fine for a low commitment start. Folks often assume lone containers end up costly by weight, yet certain nearby sellers don't follow that pattern. I began small, at first with a milligram then doubled it later on. This approach lets one container cover many weeks without running out fast. The initial compound in sizes from ten up to thirty units shows up at fair rates along with delivery, and even the bigger ones offer solid value from sources that run sample checks through labs. The other compound in five unit containers stays reasonable too, with low amounts around a quarter milligram stretching one across more than a month.
