Is 4mg+ really the key?

[Bruh132 60327]

I’ve seen a lot of back and forth on whether or not 4mg or more is where you truly get the benefits of Retatrutide compared to Trizepitide. To my understanding the argument supports that the Glucogon agonist doesn’t really get activated until you hit the 4mg+ a week. I’ve titrated up from .5mg to 4mg over a course of an couple of months and have been cruising there for about 3 weeks and haven’t really noticed anything different effect wise (Other than the continuous benefits of Reta obviously lol). Can anyone share their own experience?

I am curious to that number as well. I am only at .75mg twice a week. But I only had 15lbs to lose. Mostly visceral fat.

4 m g was my sweet spot

Real game changer from that dose onwards & I haven't exceeded 6 m g.

Journey has been 8 + months personally.

While everyone reacts differently- anecdotally the number that is generally regarded as the "switch" point is actually anywhere between 6mg to +8mg

When I was researching/learning for my transition from Tirz to Reta, the range I settled on for meaningful GCGR activation was 6-8mg, so I made it a point to get to that point quickly. I got to 8mg in early Feb, ~35lb ago.

I'm decidedly not avoidant of higher doses, I'm down 55lb I still have ~40lb to go. No regrets thus far, things are going better than I expected/projected.

It's been slow going since I got to the 4mg point.

 

[mybodyisasewer]

I've done a year+ at 4mg, and still don't like 6mg. I tried 8 mg a few months ago and it was some bullshit I had a hard time with protein shakes and I pooped 3 times in 2 weeks.

So yeah, n=1 here but 4mg is definitely the sweet spot, I don't have any side effects at all it's perfect I'm going to stay on this indefinitely.

Who doesn't like a chart?

I started Tirz on 12/12/25, Reta on 1/10/26. The chart starts at 1/10/26, the weight loss stats start at 12/12/25.

I started supplementing creatine on 5/1/26, which stagnated the loss trajectory temporarily.

It depends mostly on how much weight you are trying to lose.

If you want to lose 10kg 4mg might be too much, if you want to lose 50kg 4mg is very unlikely to be enough.

For people without significant obesity , low dose reta is probably a good option, 1mg of reta for a year caused 9% weight loss, much more than low doses of sema or tirz. And many many people on this forum without obesity seem to get good results from low doses of reta, in the 1-4mg range. So I do not think 4mg is anything special. And individual responses vary a lot. For some people 1mg causes side effects and huge decreases in appetite for others it might take 10mg to have that effect.

The glucagon agonism is going to be happening at all doses, you might need bigger doses to be able to measure changes in energy expenditure from reta, but I think that has more to do with the precision of the testing than the way the drug works.

And you need to adjust the doses based on effects on weight loss and hunger and side effects, if you are hungry or not losing weight then increase dose so long as side effects are not a problem.

5 months in, 30 lbs down, 30 to go and hit the 2 mg dosage 2 weeks ago.

Based on my personal experience so far it seems to be the case for me. I initially in my first 4 weeks starting off at 1 mg and then titrating up to 2 mg, lost a total of 14 lbs but then it sort of stagnated from there and i plateaued. 2 weeks of no weight loss until i then titrated up to 3 mg and realized food noise was slowing down and didnt have any more side effects so bumped it up to 4 and ive lost an additional 5 lbs so far since then.

I always say, biology in general is not maths. And not always 2+2 =4. There's no one rule, because all depends on a particular - personal case. But like above was said the less you need to lose, the lower dose will do for you. Also it matters whether you have some activity or not, your diet etc...

 

[JimGainz]

Have you found that it takes more mg of Reta for the same effect as less mg of Tirz?

Wait till you hit 8mg. Wife and I kind of slowed down/stalled on the last 2 6mg and two weeks at 7mg. Started 8mg and zing, appetite suppression is back, weights down 3.2lbs on my Tuesday check. BMI was down .5 and BF down .6% in 4 days

A couple things here-

You should not ever practically compare mg dosage of any of the different GLP meds. When speaking of the general scope/range of dosages: 2mg of Semaglutide will never be close to 2mg of Tirzepatide, which will never be close to 2mg of Retatrutide, as threshold limits and therefore scale, are all very different.

Aside from that, it really depends what “effect” you’re trying to use as a metric.. I’m going to go on a limb and say you’re talking about food suppression? If so, always keep in mind that the primary agonist weight for Reta is not focused on food suppression like it is for Tirz/Sema. If that effect is your primary litmus of whether a GLP is “working” or not then Tirz or Sema are significantly better options.

Food suppression intensity on Reta comes different for everyone and at different dosages, but to simply answer your question (now that I’ve placed context)- yes it will take more mg of Reta than Tirz to achieve similar food suppression. This is by design, as again, suppression shouldn’t be the only metric for efficacy when discussing Reta.

From what I can tell it's different for everyone. When I hit 4 mg the glucagon agonist really seemed to get turned on.

 

[alphaamigo]

I started seeing the different at 4mgs. But again, I also started at 4mgs after 4 weeks, and many people say that 4 weeks is actually the key. But 4mgs at 4 weeks really started the weight loss for me.

Have you ever seen anything 'real' in terms of conversions, especially from Tirz->Reta? I keep poking around in the studies or patents to try to figure out how the 'ratio' changed from last gen to next gen but can't really seem to narrow it down.

The sweet spot is your sweet spot. I am losing on avg 2lbs a week. 4 days at gym, walks most nights 1.5 miles. Tracking 90% of food to the gram, I work at home , it's easy. I do cardio 3-4 hrs a week - road bike riding. Without the extras my weight loss would be less but I have almost no side effects , I wanted to go low dose as possible and slowly move down. I did not want nasia, I wanted to be able to eat any meal within reason and be active.

I did .5mg for a month, then .8mg. 1mg and just pinned 1.3mg.

If a sweet spot exists it might be for folks only pinning reta vs all the other things one should consider doing w it. Just my 2 cents

I think you missed my point, my man. You should not be looking at any “conversion” so to speak, they behave differently, and your body will behave differently. Best course of action is to give it a go with responsible titration and listen to your body.
