You can use Arimidex while on cycle, but you NEED to use Aromasin during PCT with HCG, because I said in my previous post that HCG increases estrogen levels by increasing aromatase activity. You cannot use Arimidex in this case for PCT purposes, because Nolvadex has been shown in studies to greatly decrease blood plasma levels of Arimidex (as well as Letro). This means the best choice AI to use with HCG is Aromasin. Now, with that being said... if you need an AI on cycle and you are already going to use Aromasin during PCT, why not just use Aromasin??? Aromasin in my opinion is a far superior AI to Arimidex (and Letro is just too strong for regular use).
Once again... you need to do a lot more reading and research before beginning anything. Your posts are quite evident of that.
