Protein Supplements

I've been stocking up on Protein supplements. I now have 30 bottles of high protein vanilla Boost and 32 bottles (came in bonus packs of 8) of high protein chocolate Boost. I also have three large tubs of whey Protein Isolate powder one each in chocolate, vanilla, and unflavoured.

I'm not really sure about the Boost. I took a look at the label but could not tell what form of protein is in there. I have to do a three week liquid diet before surgery so If they're no good after surgery I'll just use them before.
