by the time I take enough 2c-e that it makes me feel like I am actually tripping decently, I feel tingling sensations in my kidneys. It is just so weird to me that it has so little effect on me when other people take small doses of it and are blown away. All the other 2c-x drugs I have tried I had an expected reaction to but 2c-e was kind of a disappointment really. Also just to add something of actual value to this thread, I would put right up there with getting a scale getting a reagent kit. You can't know what you have from reagent testing, but you can know what you don't have and take a guess as to what it might be. Usually that is enough. If you want to be ultra safe you can send small samples of your drugs anonymously to labs that test them with more advanced equipment and publish the results online, at least in some nations these labs are actually run by the governments but if you live in a country that wants drug users to die then it might be trickier.
