training twice a day doesnt equal twice as much growth mate, ive done it before and honestly i grow alot better from a 4 or 5 day split, unless one training session is for a bit of cardio, i really think its too much theres only so much you can fatigue your body in a day and i feel as if one workout will take away from the intensity of the other, my advice keep your 5 day split train with high intensity and get the job done, that way you have the rest of the day to eat and grow.
also mate, dont cut out your protein shakes they will be your best friend to putting on muscle aside from eating real food, if your feeling bloated/ fat theres a good chance its your creatine since it causes water retention. dont worry about that too much 2 months down the track you can get off the creatine and you will lose the water just as easy as you put it on. the main thing you dont want to do is be one of those guys who try to stay as lean as possible while putting on size, because i garuntee you, you will be cutting yourself short from your potential gains, 2 months isnt a long time so you wont put on much fat at all anyway just try and eat as much as you can and get all the protein shakes into you that you can get your hands on and train hard and you will put on muscle.
