How can I tell for sure that my product is real? It passes the vial test, label looks good and the cap looks authentic.

Is there a chemical test that I can perform on it (something akin to pH paper or something), or a drug test I can administer on myself at home? I want to make sure that the stuff I am putting in my body is actually nandro and not a mixture of sweet tea, olive oil, and rat poison.

Any ideas? Thanks guys!
