You can do longer cycles as a male, as long as your blood work is good, you are able to train and eat, and you are still responding.
@Grey Spartan hit the nail on the head to be honest.
With more experience you can successfully run long cycles, but first time around you will struggle to do it effectively.
The goal of the first cycle should be to put on as much muscle as possible, and learn how to control your estrogen. Right now if you take too much testosterone then you’ll have a bad time, because you won’t know if you have high or low estrogen.
