Mornin all'

I have three 10ml bottles of loeffler testosterona 4l-a (yellow box w/ dog and cat on it). The boxed were shrink wrapped, so I opened them up. All the bottles had 'flip top' on them, so I know they atleast werent tampered with from the top. I look at the bottom, because I heard you can put a hole in the bottom and remove the liquid?
Does anyone have a pic, or what should it look like?
There are numbers on the glass on the bottom, and usually a small blemish in the glass or 2, like a very small bump that varies in location from bottle to bottle. 2 bottles have a small blemish, 1 doesnt.
I guess my question is, can I test to find out if its the real stuff? Either by taste or smell or something?

Thanks alot guys.
