Go with creatine, heres one with carbs so you don't really need to take it with juice DYM Power-Tech 4lb . A cheaper route would be 4Ever Fit Creatine 1000 g and have it with some grape juice. A protein would be beneficial aswell and this one's cheap CNP Professional USA 100% Whey 5lbs .
Avoid the M1T. Your question is answered, eat, sleep, train and if you want supps I posted them above.
