RE: Walmart Supplements
It might mix horribly and taste awful. Have you not tried to buy in bulk online?
Where do you live? States or Canada?
I'm guessing you're bulking and want to gain weight?
Do you just need to up your protein or is it calories in general that you need to up so that you can gain weight?
The protein powder is not really what you need to get. It can be a convenient protein source of course, but you should go to food first IMO... then again, it depends on what you're looking for exactly.
