That is why you always at least have a basic understanding of the chem you are taking. Would never take one that hasn't at least been tested by others more... insane than I.
Lol. A basic understanding of a chemical comes from testing. Research chemicals aren't tested. That's the point. And, I'm not sure that I'd consider it tested because someone who was too dumb to realize that they were too dumb to be "testing" chemicals, didn't die. My dog doesn't die when he eats the garbage. Doesn't mean it's been tested to be "safe". Also, with your "unique" brain chemistry, do you really think that anyone's anecdotal "trip story" is going to have any bearing on how it will affect you?
Mostly the testing arena is places like Amsterdam and others.
There is a ton of testing done in every country, US included. Just need to live in a city where medicine, universities and pharma companies intersect.
