With Saint Louis being my hometown, the supplement company that you ever hear about (radio, TV, gym talk, at work, etc) is Supplement Superstore. I want to start by saying that Andy Frisella is an amazing person if you read up on him, BUT I do not like that his stores take advantage of uninformed consumers when they walk in the door.
S2 has a lot of good products, but for the money you are better off purchasing somewhere else. Most of the reps in the shop will swear that you NEED Ignition+Level 1+Commander Go-Pack (whatever the current name of it is) in order to achieve your goals. $40 for 2lbs of protein is just too high in price, it DOES taste amazing and it DOES have a good profile, but let's face it that price is a little high. Even if they justify it by saying "it's an isolate", "it's the highest quality protein on the market", or anything else they try to sell you on.
