Bests & Worsts Reviews from Amazon

Performance: Awesome. I actually can push further and harder in my cardio workouts with this than I could before. There is some tingling you feel in your muscles ( I think from the Niacin) as its working, may seem a bit weird at first, but you get used to it. I tried with 1 scoop as it says, the tingling was much less almost gone, but the effect was not as pronounced. I got more of a boost with 2 scoops. Taste: It has a bitter almost medicinal taste that is hard to mask with most types of juice. I either take this 2 ways, in a small amount of liquid as medicine and just chase it down with some other kind of juice afterwards to kill the after taste, or , Believe it or not, in black coffee. Black coffee is the only drink I have found that almost completely masks this taste for me. Probably because the coffee itself has a bitter astringency to it that kinda works with this to help mask it. But the coffees bitterness is more pleasant. hard to describe but it works. I'm talking just streight black coffee though, no added creamers sugars or anything else.
