Debunking the 4mg Retatrutide Glucagon Threshold Claim

Yes, the spread from person to person is large. The waterfall plot from the phase 2 trial shows each individual's result lined up from lowest to highest within each dose group so the range is visible.

That plot makes the jump from 1mg to the higher groups stand out. Once past 4mg the lines for most people look pretty similar through 12mg.

If the goal is to compare average outcomes across doses, the original average plot in the first post shows that more clearly than the waterfall version.

Diminishing returns are likely, but the 48-week data still had the 8mg and 12mg lines climbing, so they had not leveled off yet.

Fair point. Trials have to wrap up eventually when investors want data. It does make me wonder how much further the higher doses could have gone with more time. The compound is strong and the real-world numbers are compelling. Excellent post, appreciate it.

I planned to stay at 6mg for a while as well. The first four weeks at 6mg went well, but the last two slowed noticeably. Two weeks at 7mg did not change much. Moving to 8mg felt like starting over, with renewed effect after the first injection.

I've been chasing that same renewed feeling for three weeks now. Next week will decide whether I stay or drop back because of stomach issues.

So the claim is that something notable occurs at 4mg, but it is not the sudden start of glucagon agonism?

How long did you stay at 4mg before moving to 6mg?

I've seen the same comments about strong results on low doses. There may not be a single answer. I started in February and still have not reached even 15 pounds lost. I'm grateful this is the most progress in years, but 40 pounds remain. I've tried everything previously with no appetite: multiple daily gym classes including kickboxing, yoga, pilates, barre, swimming, sauna, boot camp, measured food, intermittent fasting, gluten-free for three years, and even prescribed phentermine produced only a few pounds.

That history sounds frustrating, yet the consistency is impressive. Back in 2016 I weighed nearly 300 pounds, switched to low carb primarily for epilepsy, and lost 160 pounds in under a year. I got into training because the lighter weight made movement easier, and diet was always the main driver rather than exercise for fat loss. Kept the weight off for almost a decade until perimenopause added about 25 pounds, which is why reta has been helpful. The current challenge is forcing enough food to support training and weekend hikes.

I like that story and the photos look genuinely happy. One trainer I followed always said results are 80 percent kitchen and the workout is the bonus. Same here with no appetite and nothing sounding appealing.

Small world. I recognize the background from low-carb circles and recall the first COSCI event in Vegas. It is interesting how this group has taken interest in reta after largely avoiding earlier GLPs. The glucagon angle felt worth exploring. I have a working idea that people who are already quite insulin sensitive tend to feel more initial fatigue on reta.

That is funny. I've been active in keto, carnivore, and low-carb spaces since 2016. I keep the current experiment private because of the gray-market aspect. Reta was the first GLP that caught attention here, partly because a few respected voices started looking into it. Strength has held up similarly to other calorie deficits. The real issue is eating enough to support training and long hikes. When I raised the dose to 1.4mg the fatigue became noticeable again.

I actually did better at lower doses. Now at 5mg it feels like things have leveled off, possibly because the body has adjusted. I had already been losing on low carb before starting and then heard the carb advice online so I stopped.

The idea that reta needs carbs may be individual. I know someone active who stalled until they added more carbs back in.

Amber's recent posts caught my eye too. She presented at the COSCI event I attended and mentioned ongoing weight struggles, which stood out in that crowd. I have not been very active in the space lately but learned a lot there. With more people now discussing reta it might be worth checking in again, though deeper investigation would be useful because the metabolic framework in that community could add context the mainstream coverage lacks.

Yes, Bikman's recent videos on the topic are worth watching. He has been shifting from viewing these drugs mainly as a bridge to low-carb eating toward examining the actual internal changes. His take on why simply saying "GLPs increase insulin" is incomplete lines up with what I have observed. I also tracked blood glucose closely at the start and saw no major dips. Electrolytes have needed a noticeable increase beyond the usual low-carb amounts.

Bikman started with the temporary-aid view but has moved to asking what is actually happening inside users. I agree the carb theory is likely individual. My own ketones rose briefly in the first three weeks then returned to the usual low level for my intake pattern. With body fat now low, there is simply less to mobilize.

Amber is a friend and might be open to discussing it. Reddit conversations on the topic tend to shut down quickly. My ketones moved from the usual 0.3-0.5 range up to 1.2 early on then settled back. With current body-fat levels there is limited room left for further loss, so microdosing for the other effects is the next step.

There are occasional decent threads on Reddit, though they are rare. One subreddit that stayed thoughtful for a while was the saturated-fat discussion group, which moved from one extreme diet idea to exploring high-carb low-protein low-fat approaches while keeping a mix of viewpoints rather than becoming an echo chamber.

I know Brad through a friend who tried the croissant diet and some heavy-cream experiments. That friend experiments more aggressively than I do.

You might still find value in following that heavy-cream experiment even if the tone is rough. The documentation was thorough and the outcome was striking for a very unconventional approach. Brad might bring interesting angles if he ever tried reta, though it could also end his drive to invent new dietary frameworks.

The delivery was off-putting enough that I stopped engaging. Still, the heavy-cream results were notable for how extreme the method was while producing clear loss.

He does call himself the same term at times. The heavy-cream log was memorable simply for proving such an extreme intake pattern could drive substantial loss. Hopefully more people from that community will explore reta and bring their usual level of detailed tracking.

Averages are meant to smooth variation, and the smoothed view still shows the clearest separation between 1mg and 4mg, with smaller further gains after that.

It is interesting to see the original post translated out and back and still carry the intended meaning without distortion.

When I was heavier, small diet and activity changes produced big results. It is good to see steady effort rather than rushing. At this stage the medication may be contributing less than the personal habits, which is fine. It can get harder later, at which point a higher dose might help or might not be needed. I reached a stable point years before these drugs existed, then regained some weight and chose to use one rather than fight it alone. The joint relief has been an unexpected bonus that makes staying active easier.
