I'm 21 and staying natural. I've been lifting for about a year and a half but just starting to really workout hard the last month. I know diet is the most important but as far as supplements I use whey protein, glutamine, and creatine. I can't really afford to go out buying every wonder supplement on the market so I was wondering if these 3 things are good or if there is something more i should be taking? Thanks
