I am a HRT lifer due to hypogonadism. I have never done a cycle of any kind. I am on 150 mg of test cyp every week and .5 arimidex every 3 days.

Now what kinds of gains would I get if I jumped up to 350mg per week of test C for 12 weeks? I would not need any PCT because when I finish the cycle I just go back to my normal HRT dose. Because of that I think I would keep almost all of what I gain. Correct?

Just want to get a realistic number of what to expect if I train like an animal and eat clean so I can decide weather or not to do this.
