A bit complicated for bodybuilders.
I saw that William Llewellyn is now selling test kits for various steroids. Didn't look closely but it wont tell you how much of the compound is present, only if it's in the product at all.
that is useless.
How about the device i posted? Its basically a mini mass spec. 250 bucks
You retarded, niigga? It's not a mini "mass spec". It's an infrared spectrometer. A totally different thing, and far less useful.
Link?
