I had a sample packet of this stuff BPI whey HD protein sent to me and it peaked my interest because it comes with digestive enzymes.... Does any one have experience with this protein?

I also saw this weight gainer. It uses Beef protein instead of whey... does any one have any experience or thoughts on the difference between a whey shake weight gainer and one using beef?

I can adjust my diet to accommodate either and I realize that they are not really comparable i was more looking for advice on the products individually. Any thoughts are appreciated.
