Several comments, but first, here are the ingredients:
"Protein Blend (Calcium Caseinate, Soy Protein Isolate, Whey Protein Concentrate, Whey Powder), Fructose, Maltodextrin, Guar Gum, Canola Oil, Tricalcium Phosphate, Natural and Artificial Flavour."
(1) the soy question; there are issues regarding whether soy is estrogen promoting (although some studies have concluded it is as effective as whey). I say why risk it when whey by itself doesn't carry such baggage;
(2) the fructose issue; fructose as the primary sweetner? what was Weider thinking? at least the maltodextrin would be an effective pwo workout option for spiking insulin levels, but the fructose puzzles me unless its solely for taste; in any event fructose is in general fat-promoting and not the best option;
(3) usage: if you are using it for pwo purposes, there is no reason to ingest a protein with caseinate, which is slower dissolving; traditionally, you want the protein which will be absorbed the quickest by the body (whey); if you are using it before bed, caseinate is preferable over whey; as such, I'm not sure what purpose this product is intended to serve (although granted, many people use blends).
(4) calorie to protein ratio; I call this protein efficiency (loosely translated as "how many calories must I consume to obtain each gram of protein?") Most protein powders on average have 120 calories per serving which gets you about 24g of protein (i.e., a protein efficiency of about 5:1). With the Weider product, you have 170 calories yeilding 18g of protein (i.e., a protein efficiency of over 9:1).
My conclusion: This product was designed more for commercial purposes and catering to the masses, rather than a serious bodybuilding product. By this I mean no offense to you, because I think we've all purchased such products at one time or another.
