This is my first time using winny. If you decide to drink it, is it a must that you drink it on an empty stomach? Somedays i'll take it in the morning, others i'll take it before i workout and sometimes i'll take it with my post-workout shake.....

Some of the powder decided to crystalize and stick to the side of the vial . Is it still good? It's T***F***** Oil Based winny, btw.
