I haven't used a lot of stuff, but I will tell you about what I have.:
right now I am using Elite whey protein isolate - Dymatize Nutrition
I have used:
MAXIMIZE by iForce - Raspberry Lemonade, Worked great, Tastes like shit.
It was a pre-workout supp. with creatine. Didn't mix well either.
CE2 Hi-Def by MRI - I am going to use the bottle and never buy it again. Way over
priced. Not really feeling or seeing a change.
NO2 Platinum by MRI - Again... way over priced.
Black Powder by MRI - Again... over priced, gave me the jitters and the shits.
I have also used Muscle Milk. I used it because of convenience. You can buy it at most stores.
I used to think that if it was expensive then it must be good for you and work like it should. I have since matured with my desicions and do more research on a product before I buy it.
