guys, here is some info that may be of interest to you. A friend of mine recently told me not to take arimidex because it can lower IGF-1. I was kind of skeptical because I have never heard this, and because I havent seen any info stating this. Well, this morning I went to my doc and asked for arimidex, he said not to take it cause recent studies show it can lower gh levels. so he gave me femera. I am going to try to find these studies and get more info.
