After a while, if you don't mix it with something other than water, you'll end up burning your tongue like I did.
Liquid nolva is super strong. Tastes like rubbing alcohol. Hell, it's worse than that.
I would mix it with a little OJ, maybe 3 ounces or so.
I hate sugar, so that's why I said such a low amount of juice.
I don't put it under my tongue. I try to get it down my throat as fast as possible.
