I've come across a lot of cheap/good benzo vendors on the darknet, specifically Agora. The vendors had been thoroughly researched prior and seemed to have pretty much flawless feedback. However, the products are 99% of the time not what they say they are, they're generics or something from China/India/IDK. Are there reliable vendors on there that are actually selling the real deal?
What country are you ordering from? At the moment the UK if flooded with pharmacy diazepam, this is not knock off stuff, this is the benzos that you get from the chemist prescribed. There are a lot of fake companys that fake export them and there is HUGE blackmarket scene, they come literally straight from the government produced factories, with NHS leaflets, you wont get better price/quality ratio. :)
