i just bought 10lbs of Met-Rx Protein. its pretty cheap and tastes great (chocolate)
check www.prosource.net for cheap met-rx protein
don't get suckered into brand name being necessarily the best. as long as it has a good protein serving (it should have 15-22 grams per scoop. and any label that has the serving as 4 scoops worth is just lame, i always lol at labels like that, sure, use the full serving, and have 30 dollar protein last a week) and has a good amino acid profile and is whey or a blend with whey being the predominant protein. you can find off brand stuff that is cheap and covers all these factors. or you can spend more, and get something like nitro tech, which is still a quality product.
dude.. dont listen to them.
Check out ronnie, he uses BSN stuff so its obvious that BSN stuff makes you huge.
As well, Jay and Dex use Muscletech, does are good too
look out for BSN and Muscletech dude, Quality stuff!
I personally like to use
ON(optimum nutrition) http://www.bodybuilding.com/store/opt/whey.html
there are other good ones too, dont fuss to much over it. if your going to fuss..... fuss about basic nutrition and stuff.
noobies tend to fuss over the PWO etc... and ignore all other meals, dont make that mistake.
(dont bother with BSN and muscletech, mostly paying for the brand not the quality, i was joking)
