Yesturday I got 4 jugs of clen from my UG supplier. All of them were clear like water, except one. I know they are suppose to be clear but one had a yellow tint to it. But it wasn't thick like test and it had a clen label on it. I am wondering what the hell it might be. Or could he have just used oil to base it with, hence giving it the yellow color? I didn't know and he hasn't responded back to me yet.
