litmus test or test kit for powders?

[swinging_away]

I did a search with some keys words and did not come up with anything. Is there such a thing on the market to test powders before you go through (and maybe waste) your brewing materials and time?

I am only interested in something for testosterone (test E to be specific)

Mass spec or if you trust your source then get an assay report

Hormone melting point tests work as well.
