I am using pro complex as my protein... great protein. it is a little pricy though... the pro at my local supp. shop (not gnc) gave me a free sample of vpx stealth. its a little cheaper, mixability isnt great but flavor is good... those things aside my only concern is the quality of the protein. im not very educated when it comes to nutrition panels, and was wondering if anyone is familiar with the stealth, couldnt find alot on it... any suggestions on a protein that competes with pro complex. thanks
