I was wondering if anyone takes the supps from walmart? Right now I am taking ON Whey and PrimaForce CEE

Age 36
Goal-gain a lot of mass, then cut

I noticed today that Walmart has protein and creatine at a silly low price. Is this stuff any good? The ones they had were:
Six Star Prof. Strength Whey and Advanced Creatine
Body Fortress Whey
Body Fortress Creatine

When my CEE runs out I was thinking of taking Vitargo or Green Mag, not sure which is better- still reading and reading and reading. Any advice on what creatine to get would be most helpful.
