I've done it, yep... still doesn't taste as bas as Optimum's Amino 2222 tabs though... yet worst of all was my ill-fated foray into their Amino-Liquid line a few years back... that **** WILL put you into a coma... I took a mouthful from the bottle, immediately vomited through my nose, and realized the **** is concentrated... and you know what? watered down, it still has been the single worst tasting substance I've ever encountered.
