There's alot of good information on getting your diet in check on this and other forums. Just do a search. Get a good workout programme as well, not just something from a muscle mag. Focus on compound exercises like bench, squats, rows, military press, and pull ups. Make sure you get lots of sleep.
Eat, train, sleep, copy past copy past copy paste.
Once you've looked into that there's nothing wrong with using some supplements (don't really care what brand, go for whatever is cheapest at your local store).
Whey protein helps keep your protein intake up.
A multivitamin keeps you healthy during intense training.
Creatine is just about the only proven performance enhancer.
Start with these three supplements, that's all.
Sorry if I offend you
Its just my point of view
