MGN Whey: 7/10 Cheap, tastes reasonably good, not sure on the quality. Did I mention that it's cheap?
MGN Huge Impact: 8/10. New product, clearly in the experimental phases. One batch was incorrectly made and gave me a bad reaction, but otherwise it's done reasonably well.
Fish Oil: 10/10
ZMA: hard to say...I've been taking it for a month, and I don't notice that much of a difference...who knows. I take a basic multi, and I feel like some of the ZMA hype might just be...well..hype.
Since I mentioned another brand of product, I should say that if I had more money I would be buying Biotest no question.
