freezing a bottle of test ?

[ray425]

Putting a bottle of test 250 in the freezer for 1 1/2 hours. Is this a sure fire way of telling if there is reaaly test in your bottle or just oil ?
cause I did this and in one bottle Isee nothing other than a few little bubbles of air floating around in it, the other brand I did this to I see what seems to be crystalization, almost milky I guess...

Short answer? No, it is not.

You could aways pull out a CC, do a methanol extraction. Distill off the methanol and do a melting point test of the 250mg that comes out (if, in fact, anything does)

Well, I dont think it will tell you much because even if it does crystalize, which it should, you dont know what that precipitate is! I would be suspicious though if it didnt precipitate something. Maybe if they used EO or another solvent it wont crystalize, not sure.
