question about buying suppliments

[schilds]

in getting my prep stuff together to start the training i have noticed that a lot of stuff is kind of hard to find and or it is not the right "blend".

the ZMA - i found at a few online stores only. i found something at GNC which was Potassium, Magnesium Aspartate and i would have to buy the zinc separately. is this ok or not, and could someone point me to a place that i might beable to buy online that has it in stock? Will this effect my results on the program at all?

i was not able to find the "Precision Protein" at the store. when i look it up online i found that EAS has discontinued this product. Is there something else that can be used instead and where could i get it from?

another is the antioxidant. what is it and where would i be able to get this one from as well?

There are a few others that we were unable to get at the stores, IE the Ultra Fuel. So if we do not have these will the results be impacted? If so how severly?
