I was wondering if it is best to take an armotase inhibitor while on a cycle or does it not matter what type of pct pill you take and I am having estrogen side effects because I am not taking a PCT while on cycle and I dont think I will be able to get my hands on arimidex or letro so i found what seems to be a cheaper armotase inhibitor called estrogenex can anyone give me any feedback about this stuff and any advice will be helpful.
