Forgot to add. If you want to get BIG, you need to EAT! Consume the adequate amount of calories for maximum muscle growth with fresh lean meats, whole grains, tons of veggies, and fruit. Absoluately no processed/purified foods containing corn syrup, sweets, chips, etc, etc.
I know food is really expensive these days and besides, eating all the time is really hard so PROTEIN SHAKES provide the extra calories and to maximize muscle growth. I know I am EXTREMELY biased and sceptical when it comes to protein powders, for instance, I prefer to stay away from those with artifical sweetners (as to why, that is another seperate issue...). For your powder, I reccomend buying in bulk to save money. And stick to protein isolates and not protein concentrates which contain many impurities such as fats that make it harder to digest. The bioavailability of isolates compared to concentrates is a lot higher too, so read up and educate yourself. Good reliable companies are those that dont spend millions on marketing their product in muscle magazines; the bigger the brand, typically the cheaper the product because in the end, they don't have enough money to spend on quality ingrediants. So, given that, I'd stick to brand names such as ISOPURE and BIOPLEX and especially www.trueprotein.com
where you can create your own type protein you desire, that is an especially good thing.
That's about it. Lift like there's no tomorrow, educate yourself, and EAT!
