Sincerely i have tried many whey protein supplements but i am not sure whether it did anything for me. right now i am getting better results with no supplements BUT a very healthy and strict diet. Creatine is also useless just bloats you with water and is bad for kidneys. . The only thing that probably helped was BCAA Aminocore by allmax nutrition.
right now i only take vitamin C, fish oil , and magnesium. i take also arginnine from time to time + VERY good diet
