Just before I started TRT, it was the first time I tested IGF-1 and it was just above range - 252ng/ml(44-280). The TRT specialist from USA that I consulted said it is totally fine. The thing is I’ve been on caber for several months and later I found reports that caber can elevate it significantly. But I’ve been also on metformin, which should reduce it. The doctor did not explain why it was fine.
3 months after starting TRT it has further increased to 280ng/ml which I guess is expected. We also made a consultation and he said it is OK. I decided to test it again today, result will be ready in a couple of days.
I read studies that high IGF-1 can cause sleeping cancer cells to grow and puts patients at a risk for developing cancer. I also did not understand whether a cancer under development can cause elevated IGF-1. And in fact I have no evidence mine is elevated from the cabergoline because I havent tested it before starting caber.
Should I be worried about this IGF-1 and what further tests should I take to check If Im at a risk?
I know some optimization doctors that put their patients on GH even chase IGF-1 of 300 and many of them consider elevated IGF-1 above range to be a good thing. So the topic is very confusing to me…
