You didn't state what your whole workout was, but: If that bicep thing your doing is an example of the rest of your lifting program than you may want to rethink your plan. 50 minutes, for chest only, seems too excessive, also. Any 15 minute, or other time period, cool down will not be needed. To get big you must do the Big Boy exercises. Of course we all know what put's muscle mass on the quickest: squats, Dl's, rows, benches, dips, etc. Might try upper body on Monday. Lower body on wednsday anf the following friday, back to the upper body work. Next monday start with lower body training, wednsday, upper body, etc. Keep any muscle group to 4-6 sets max each workout. And have at lease one day completly off between heavy workouts. You can also try full body workouts, 2 or 3 times a week, keeping the total sets down to between 9-12. Either version of these short intense workouts have helped thousands of men gain muscle mass, in a somewhat short period of time, over the years. Try not to fall into the trap of 5 or 6 day a week split if you want to gain pure mascle mass.
Might want to have a shake to replace at least two or 3 of those all day eating binges. Much easier on the digestion and to assimilate all that nourishment you spent the big bucks on. Gear does not give the same results to everyone. Some guy's will gain very little, some will blow up like a puffed up balloon. Either way, using gear does not assure permanent or stable muscle gains. People are going to have stop taking it at some time in their future lives and that's when a normalization of the body reverts back. Meaning a lot of that hard earned muscle tissure will reduce in size. If you cycle it as your should, with long periods between cycles, than the results can be more long lasting and the health issues hopefully less. Troubles is , most guy's don't cycle (after awhile) and shoot the butt, legs, etc just about daily. There lay's the problem. Good Luck.
