I took the advice from my previous thread, allowed the liquid to evaporate on white ceramic, and tested the precipitate. It had much, much clearer results.
As I'm sure everyone will want to comment, you can't know absolutely definitely the composition of the liquid without performing GC on it. However, this is what I can afford, and it's conclusive enough for me to decide that I will consume the product.

In my personal, unexperienced, uneducated-in-chemistry opinion, the liquid is legitimate. The ehrlich purple was deep and fairly immediate. The marquis result was a solid brown (no green shades), pretty much instantaneously. I wasn't able to get a good picture of the 3-minute marquis reaction. In my photo, it looks black, but it was actually a deep brown. From what I've read, 4-AcO-DMT would have been lighter/greener. Once again, to know for sure it would need to be sent in for GC.
In my opinion, the liquid is legitimately what Trip says it is (a shroom tincture, therefore "liquid psilocybin"), and I will be ingesting it eagerly!
I hope that my effort will be useful for anyone trying to decide whether or not to purchase.
