Participants discuss a trial subject paused after liver function abnormalities and note his extreme weight drop of nearly 180 pounds in ten months. Several users report their own elevated enzymes on retatrutide, some linking it to fast fat mobilization from the liver while others see no change despite long-term use. Rapid weight loss is cited as a known trigger for temporary liver stress, and concurrent medications like statins are also suspected. The group generally agrees that more data is needed before assigning blame to the drug itself.
What this discussion establishesWhether the liver issues are primarily from retatrutide, the speed of weight loss, or other medications like statins.
Still openWhether the phase 3 subject’s abnormalities will resolve or require permanent discontinuation of the drug.
Nothing here is advice.
Someone in a phase 3 retatrutide study just got unusual bloodwork back. I believe he mentioned being on the top dose. Like the rest of us using it, he’s hoping the medication isn’t responsible. The discussion he posted notes it’s been four weeks since his last shot after being told to stop because of liver-function problems and other blood-count issues.
Maybe this kind of outlier explains why the company isn’t highlighting retatrutide much in their investor updates lately.
I don’t think it’s the drug. Something like this would have shown up already in the earlier studies if it were. Then again, maybe I’m just hoping it isn’t the cause.
I’m sitting in the hepatologist’s waiting room right now. My liver enzymes jumped higher than they were before I started and it’s not from fatty liver since I don’t have that.
Been using it more than a year myself. I get bloodwork every three months because of an autoimmune condition and the immunosuppressant I take, which can also affect the liver. Nothing has shifted since I began.
Losing weight very quickly can dump a lot of fat into the liver all at once and sometimes trigger serious inflammation or even failure. Slower loss, especially in people who already have fatty liver, usually improves the numbers instead. The safe pace is roughly three and a half pounds a week at most. Being obese carries risks, but so does dropping weight too fast. We don’t know yet how long this person was on the medication or how much they lost, so blaming the drug right away seems early.
That could explain it. He began the study in early May last year weighing 355 pounds and was down to 176 by March, so 179 pounds gone in ten months. That works out to about four and a half pounds a week on average, which is well above the limit mentioned.
Probably a dumb question, but do the researchers ever tweak the actual molecule based on what they see in trials, or does the formula stay fixed the whole way through?
How high are we talking? More than double the upper limit?
Could also be someone who drinks more than average. My knees have been aching two days after every injection lately, oddly enough.
It’s a single molecule, so I doubt they can alter the structure itself. They might adjust dosing or how it’s given, but I could be wrong.
Any change to the formulation would probably force them to restart the entire trial process since it would count as a new compound.
It’s possible a small number of people get liver problems from it while the drug still turns out to be generally safe and effective. Almost no medication is completely risk-free. We’ll know more once all the details come out.
They’d have to begin again at the first stage of testing.
My July 7 numbers showed ALT and AST well above three times normal even though bilirubin was fine then. By August 7 both had come down a bit but were still high, and bilirubin was now out of range on two measures. My doctor told me to pause retatrutide but thinks the statin is the more likely culprit and said I can keep the other GLP-1. He lowered the statin dose. I booked my own follow-up labs for early September and plan to resume if the enzymes stay under three times normal. I suspect the rapid loss of liver fat is what’s driving it.
A handful of people have dropped out of the trials over rising liver enzymes. Mine have been climbing too. According to what I’ve read, it’s probably just the liver reacting to losing its fat stores. My ALT went from 33 before starting to around 100 now. I’ll stop if it hits 150 and I’m testing weekly. An MRI last year showed I had plenty of liver fat, so that fits. I haven’t lost much weight overall, so it’s not from huge fat shifts. Enzymes only show current stress, not past damage, which means normal numbers don’t always rule out fatty liver. Only imaging confirms it. I’m also tracking fasting insulin closely.
Hopefully it settles down and maybe the GLP-1 will eventually fix your lipids so the statin isn’t needed. Bodybuilders often see the same enzyme spikes from orals and they usually drop back after a few weeks off.
Nothing guarantees the weight will stay off without the medication, just like nothing guarantees you’ll keep losing. Still, the liver matters too much to ignore. In the end it’s your call, and staying well hydrated might help it clear whatever it needs to.
Just got my second set of labs after four months on 5 mg weekly and my liver panel is the best it’s ever been. Same with uric acid and cholesterol.
I also had high ALT and AST while on it plus another medication. Stopped both, waited three months, and levels normalized. Restarted retatrutide alone and the numbers stayed fine. Other common triggers include certain pain relievers, intense workouts, stress, or poor sleep. There’s a good database for checking substances that affect the liver. Best approach is to remove as many possible causes as you can, get back to baseline with medical approval, then think about reintroducing things slowly.
That database turned out to be really helpful.
Usually you don’t want to add yet another substance, but have you thought about glutathione shots? I have a supply I’m holding off on starting until I finish a cycle that was hard on the liver.
