You think that's all there is, huh? Just consume more calories than you expend and you'll magically gain LBM.
You definitely need to leave the supps alone until you can get a clue about nutrition and the importance of nutrient timing.
How much is "lots of protein" exactly? You think a supp will counteract your nutritional ignorance?
If I were you, I'd just stick with the weight gainer since you see nothing wrong with your nutrition.
Holy crap - where do these know-it-alls come from?
