I was fine on it. I've cycled it 4 times. Never more than 4 weeks, with perfect life support supplementation and PCT.
I'd say that if you are ready to play the the big dogs, before you get off that porch, read, read, read and when you are done, read some more. I have a great PCT protocol if you want. PM me and I'll give it to you. I've sent it to a couple of users. It works perfect and helps you recover from the shutdown.
Don't go over 40 mgs and only run that high for maybe your last week, but if lethargy is bad, cut it back down. I always went 10/20/30/40 and then was on PCT for about 6 weeks after. With proper research you will keep your gains and enjoy the cycle. Without it you will have estro rebound, gain fat, and lose your gains.
I recommend it and wish you the best!
