BTW: The reason you want to take a quality whey protein is not for weight, but because it contains all of the necessary precursors for your body to manufacture glutathione. Cancer patients tend to have depleted glutathione levels, and oral glutathione is usless. You must either get it IV or take precursors such as Immunapro. That is why it is so important to get a high-quality product. I used to use Immunocal but it is an MLM product, and thus it was more than 2X the cost of Immunopro, and Immunopro is higher quality.
