RE: Creatine & whey
Yeah the supp industry is flooded with products.
The powder works out cheaper and if its monohydrate, the only reason to buy capsuls is convience.
Besides whey and creatine, you need fish oil (take 2000mg a day) and a solid multi-vitamin. I recommend NOW EcoGreen, NOW Vit-Min 100 or Optimum Opti-Men.
Fish oil wise, any will do.
