I bought two of these and saw no results what so ever, I actually lost weight. The mix has a hard time totally dissolving so you will routinely drink big clumps of powder. Also the mix does not last long because they have you using one big scoop per serving. The scoop is one cup I believe. I recently bought GMC brand of whey protein and there is no comparison. GMC's stuff actually tastes good and I don't mind drinking it. Anyways you get what you pay for.
