I have ordered 2mg Xanax bars from liston once last year and I was very satisfied with the bars. They were solid, big and properly dosed. The stealth was already utter crap in this shipment (a resealable bag wrapped in cloth!?)
Now I ordered from him again and the entirety of this Xanax shipment is made of either entirely bunk bars (or maybe they are just extremely underdosed). I had multiple people try a full 2mg bar of this batch, some of these people with very little tolerance to benzos, and not a single person experienced the regular xanax-high. I personally believe there might be another substance in these rather than alprazolam, because I believe I feel some sort of haziness on them, but it's a very weak and brief effect.
There are various scam reports if you google his name, a lot of them popping up in recent months too. Now I'm just mad that I didn't listen to the bad reports I saw before ordering from him again...
Probably diazepam/eitzolam in the bars, if you get your hands on a reagent or send it in for lab test let us know, I'm very curious as i loved to use liston on SR and he was a decent vendor most of the time (in my case) i have heard good and bad things about liston for years.
