Dtimshell saidI've tried creatine pills, testosterone suppliements, protein shakes, whey protein powdershakes and many others in my young naive lifting youth, don't try it, they're all cons, you should need nothing more than a nice healthy protein rich diet to gain muscle.
PS EAT EAT EAT EAT EAT! and eat again! thats all I do!
umm... whey protein is not a con.
To the OP, I recommend whey protein, glucosamine, flax seed oil, and a multivitamin. Creatine only has a great effect (that I've observed) on vegetarians/vegans because you ingest it naturally through foods like fish. A theromgenic or energy enhancer like NOXplode can be beneficial, but many people aren't comfortable with it so I would try it out before you drop 60 bucks on a tub you won't use. Creatine is also in NOXplode so be careful not to double up on supplements. But really, the best thing you can put your money toward is a great protein powder/mass gainer (if that's your goal, but I think you're trying to get lean) and eating plenty of healthy food.
