Lowest dose?

Summary

What starting dose of retatrutide is too low and how should titration be guided?

The original poster is on 1.5 mg reta weekly with mostly good appetite control that fades late in the week and wonders whether to increase or split the dose. Replies advise going slow, using hunger return as the signal to titrate by 0.5 mg every two weeks, and note that a single weekly injection may give a stronger signal than split doses. Others stress that weight loss of 1-2 lb per week is sufficient reason to stay put and warn against chasing complete elimination of hunger.

What this discussion establishesWhere people disagree

Whether splitting the weekly dose is helpful or whether a single larger injection is preferable when side effects are absent.

How to balance sleep side effects against continued use of reta versus switching compounds.

Nothing here is advice.

I'm on 1.5 mg of reta once a week. Food noise stays low except it starts to return toward the end of the week. I notice many others are using much higher amounts, 6 mg or 8 mg, plus the study doses. Is my dose too small? Should I raise it gradually each week once effectiveness drops? I've also thought about splitting the dose into two injections per week instead of one larger one. I'm new so please go easy.

It's fine to move slowly. I started my wife at 0.5 mg because she worried about side effects. If you've already been at 1.5 mg for a couple of weeks, go up to 2 mg for two weeks, then add another 0.5 mg every two weeks until hunger no longer bothers you. For example I inject Sunday evening and if hunger appears on Thursday I know it's time to increase; if it waits until Saturday I stay put. Because of how the levels build I don't see a need to split doses for better results, though splitting can reduce sides. I'd rather see one 3 mg shot than two 1.5 mg shots 3.5 days apart if there are no sides, since the single larger dose gives a stronger signal. Splitting is harmless but not required. Taking it slow is smart and often leads to better long-term outcomes.

Thinking about going all out or quitting entirely, but I'm joking around. Did the medication help you drop any pounds so far? What's the duration of your experience with these compounds? Most details came from your initial post. Are the nighttime troubles persisting with this one?

There are a few ways to handle dosing. One is to pick a high target dose to maximize weight loss speed. Another is to keep the dose as low as possible while weight is still coming off. The common approach of letting hunger guide increases feels natural but risks chasing an impossible target, like raising a painkiller dose until pain is completely gone.

YES. The first three nights after I pin I sleep but never feel rested at all.

Funny, I'm the exact opposite. I can only sleep 4-5 hours even though I force myself to stay in bed longer, yet I wake up fully rested. Though maybe the newborn changes things for you and not for me.

I really appreciate how useful that turned out to be.

This is helpful. I'll keep titrating as needed but I'll remember the part about the unrealistic moving target. That makes sense and kind of worries me.

Another point that often gets missed is that our goals don't match the trials exactly. Our goal is weight loss, so let that decide. If you're dropping 1-2 lb a week there's no need to change anything. If the scale stalls for a week or two it might be time to go up, or it might be time to check whether your maintenance calories have shifted because TDEE drops with weight. I also know the scale dropping gives a dopamine hit that makes me want to raise the dose even when I know I don't need to.

I looked over my measurements once more, focusing on pulse, and switched to the other option when the drawbacks became an issue. Yet reta does have some benefits:

What matters most to me is whether I'm satisfied with the advances I've made. In cases where that is true, raising the amount isn't something I consider.
