Crazy Dosing Chart

Summary

is this retatrutide dosing chart safe or too aggressive

The thread centers on a chart that escalates retatrutide doses rapidly to very high weekly amounts. Nearly every participant calls the schedule excessive and likely to cause severe side effects such as vomiting or diarrhea. People describe their own slower approaches that begin at 1-2 mg and increase only when needed, often staying well below the chart's levels. Clinical trial data is referenced as a more measured guide that still moves slower than the chart.

A newcomer on another forum got told to follow this chart for reta. She checked on discord and was warned it looked off. People should watch where they take dosing advice from.

Those numbers look way too high to me. I have always started small and increased only when necessary. Makers push higher amounts because it sells more product. I began at 1 mg weekly and now do 500 mcg three times a week and that works fine for me. Some people may need more but the rule is still start low.

AmberAlder26archiveDec 21, 2025

That chart jumps way too high. The safe way is always to begin small and raise the amount gradually. You cannot take the dose back out after it is injected.

I have been searching for a chart that matches the actual study protocols. They seem harder to locate than expected. The practical approach appears to be starting at the smallest amount possible and raising it very gradually. Even the study schedules might be on the high side because they aim for the strongest outcomes.

Searching Eli Lilly phase 3 trials will show the doses they tested without much trouble.

By week 7 the chart has them using 2 ml. That would require a 3 cc syringe and a 23 or 25 g intramuscular needle. Might as well add tren to the last ml. Hard to believe.

CopperQuill51archiveDec 22, 2025

Everyone reacts differently. Most sensible users begin with a small amount and only raise it when the effects are not showing up. They do not follow a fixed chart. The key is paying attention to how your own body responds.

PlainPebble75archiveDec 22, 2025

The trial used five steps every four weeks: 2 mg, 4 mg, 6 mg, 9 mg, then 12 mg. Other people doing their own research say they start lower and often get the results they want by stopping at 2 mg or 4 mg.

All I picture is someone rushing to the bathroom to be sick. Low and slow seems like the right way. Raising the dose too quickly can bring on new side effects that were not a problem before.

I do not understand why anyone would use amounts outside the trial ranges.

Yeah, that's my take as well. I'd steer clear of going beyond the suggested amounts. Using a smaller quantity or stepping up more gradually works okay for me. But exceeding that limit? I just wouldn't do it.

This kind of thing is what gets people hurt or worse.

PatientTimber17archiveDec 22, 2025

I began at 1 mg for four weeks and then moved to 2 mg for another four weeks. After that I will decide whether to go to 4 mg or stay put based on how things are going.

KeenPebble77archiveDec 22, 2025

Are they mixing this themselves? Why would anyone want to inject that much volume? I use 6 mg per week and the shot is only 0.12 mL.

CopperAlder51archiveDec 22, 2025

I would never be able to go to the bathroom again on that schedule. Just crazy.

NorthQuill17archiveDec 24, 2025

Wow. Everyone is different but you should at least wait a couple of weeks or a month to judge how a dose is working before raising it automatically. I started at 2 mg, went up to 6 mg, and have now dropped back to 2.5 mg and might lower it more.

ClearHarbour45archiveDec 25, 2025

The point is reta tops out at 12 mg and is not approved, so this plan has you at 20 mg after seven weeks. You could do that with 40 units, not 200 units which is two full diabetic syringes.

SteadyLedger49archiveDec 25, 2025

Overdoing glps is serious. That chart is a direct path to trouble.

It really is. I see so many extreme examples on Reddit that I have to read them twice to believe it because they could be so harmful. Some people are new but the number who have not even looked up basic mixing and dosing before injecting unknown powder is surprising.

SharpHarbour48archiveDec 29, 2025

They would lose weight quickly on that plan because they would be in the bathroom with diarrhea the whole time.

It looks like they copied the tirzepatide schedule.

↳ replying to @WarmHarbour52

Only if you also ignore that the dose goes up every week instead of every four weeks.

WarmHarbour52archiveDec 29, 2025

I did not even notice the weeks. Oh dear.

If they are lucky it could go the opposite way instead.

CopperAlder51archiveDec 29, 2025

On the bright side anyone who tried this would probably already be in the news.

BrightAlder79archiveDec 29, 2025

It is interesting how many people want to reach a working dose fast. I plan to start reta once I have a proper source. I used sema for a few months at 0.25 to 0.5 mg max and lost 30 lbs. When I tried 0.6 to 0.75 mg the side effects were too strong. Everyone is different so caution is better.

PlainWillow35archiveDec 29, 2025

This is why we cannot have nice things. Anyone who follows this schedule will probably end up on Reddit posting from the ER.

PlainKettle41archiveDec 29, 2025

That schedule must come from someone trying to move single vials quickly.
