Fasted Insulin Went Way Up

[peptidepower77]

On Tirz my fasting insulin went from 10 down to 3.4, which is sort what is expected on a GLP1.

I've been on legit reta (verified by a third party lab) for about 5 weeks. Last week I did a fasted insulin test, and it came back as 33. I assumed it must have been a lab error, since it's like 10x the last value that was only two weeks earlier. I did it again today, and it came back as 33 again. That defies everything I know about GLP1s. Anyone have any thoughts? I thought after the first one maybe I swallowed some toothpaste or something accidentally, but I was super careful for the one today.

My HbA1C was 4.8% last time, and today's blood sugar was 86. So those are fine. But my fasted insulin has skyrocketed and I don't know why.

This is a potential sign of metabolic dysfunction - not lab error given your two tests. Your A1C and fasting glucose are low because of that insulin level - which isn’t sustainable. If I were in your shoes I’d stop with the Reta you are using and see an endocrinologist asap. Your pancreas will not be able to handle that amount of insulin production for much longer.
