Summary

experiences switching from reta to tirz when maxed out on dose for further fat loss

One user at 12.9% body fat on maximum reta plus cagri for 1.5 years asked about switching to tirz and starting doses. Another reported switching due to reactive hypoglycemia, finding tirz plus elora more effective than prior combos. A third emphasized that reaching single-digit body fat requires consistent tracking and deficit rather than higher doses, while a fourth noted limited research on GLP use at low body fat and differing risk-benefit ratios.

What this discussion establishesWhere people disagree

Whether further fat loss at 12% body fat should rely on dose escalation or on learning maintenance and consistent deficit without heavier drug reliance

Still open

Whether a switch to tirz would actually produce better results or what starting dose would be appropriate

Nothing here is advice.

Hi folks. Hoping for some perspective even though everyone responds differently. Been using this compound a year and a half, deep in a cut with a set meal plan. I know my way around food and lifting, sitting at 12.9 percent body fat and aiming for about 9. The issue is I have reached the top of the dose range at 6 mg twice weekly and the effect seems to be fading fast, even after adding the second compound. Has anyone here moved over to the other main option? Did it work out for you? What dose did you begin with after the change? Really hoping for a shift because options are running low.

I moved from the first compound at 15 mg over to the second one. I had also been stacking the third compound but it did not suit me well. The reason for changing was reactive low blood sugar episodes. The new main compound eased that somewhat. Currently I sit at 12.5 mg of the second compound plus 5 mg of a fourth one that works better than the third. Overall the second compound feels slightly stronger for me right now. I might go back to the first one later but this stack is doing the job at the moment.

Speaking as someone already under 9 percent, getting down to single digits is not mainly about the compounds. A steady calorie deficit is what matters. Track intake and stay consistent and the fat will come off; skip that and it will not. At 12 percent it is time to consider maintenance dosing and tighten the diet instead. A steep deficit while already at the top dose does not line up with claiming solid nutrition knowledge. Pushing high doses to rush to very low body fat is not the smartest route. Focus on training and eating properly if the goal is that lean.

Fair point given how little detail I provided at first. I should have explained more. Still appreciate the feedback.

For most people who end up above standard maximum doses or stacking these compounds the risk level is acceptable because the dangers of severe obesity are far higher. Nearly everyone in that situation still has weight to lose even at the top doses. Starting from severe obesity a year and a half ago shifts the risk calculation a little but not much. Most health gains come from moving out of severe obesity into the obese range; after that the picture changes and fitness may matter more than exact fat percentage. Aiming for 9 percent with these compounds has two problems: almost no research exists beyond forum reports, and health risks at 13 percent are basically the same as at 9 percent so there is no major healt

I run 8 mg of the second compound together with 7 mg of the first one and that combination works fine for me.
