Who is TripWithScience

TripWithScience has been selling the same product since 2011, vials contain Liquid Mushrooms (Psilocybin extracted from PSILOCYBE CUBENSIS mushrooms in a clean ethanol/distilled water solution) that were priced at 19.95$ for 1 vial with discounts on large amounts.
As Trip explained on his profile:

“Liquid Mushrooms” are simply the psychoactive element of Psilicybe Cubensis Mushrooms (Psilocybin) but extracted in its pure form, separated from all of the fungal material, spores, and fungal defense mechanisms that mother nature evolved to cause nausea in mammals (like you!) so that their spores could survive a mamilian digestive tract.
Each 10ml vial contains ~9mg of Psilocybin (equivalent to the Psilocybin content of 2g of dried shrooms).
So one vial contains enough psilocybin for a fun, solid trip, with plenty of visuals. If you are light weight (under 130 pounds) you might only need ¾ of a vial.

Trip has extensivly explained how he was making his “Liquid Mushrooms” vials but according to the court case he was actually selling 4-Acetoxy-N,N-Dimethyltryptamine (4-AcO-DMT). This controlled substance is an analogue of 4-Hydroxy-N,N-Dimethyltryptamine (liquid psychedelic mushrooms), a schedule I controlled substance.
