Musclemania® Canada Physique Champion Giancarlo Castaldo is training for MM Universe and his MM Pro debut. The 5'8", 185 lbs., 21 year old, lifetime natural says, "For the last week of my prep, I am on a white fish diet to get extremely lean. So far my energy levels are good because I'm compensating low carbs with high fat and killing every workout 7 days out."
