I generally buy the 10lb bag of ON 100% whey and mix it with other things like ON Serious Mass. or Protein Factory aussie casein. The ON has glutamine peptides and lactase enzyme for us lactose intollerant
Neither. Go with www.vitalus.com if you are looking for both Quality and Price. Nothing comes close to it in either (afstores ISO AGB is better quality), but no one can compete with them in the price category. YOu must order it my 20kg bags though. This is A LOT OF PROTIEN.
