I have recently tried Isowhey for about a week and I can already feel some effect. At first I was quite skeptical but I have to say it's one of the best product to support weightloss exercises. Isowhey contains highly refined protein, which I feel is a lot more effective than any other products out there.
To get a real amount of protein (25gm +) you can always take the proper Whey Protein powders that have been available for a long time from brands like Twinlab.co.nz
