It sucks that i have to keep posting this. Don't do it OP.
You need to realize that pentobarbital is a highly controlled drug that is mainly used to euthanize animals. It's not a recreational street drug that can be found anywhere. It has no recreational street value and there is no widespread demand for it.
Supply is heavily monitored and so it's rare for it to be diverted. No one is selling this shit because it's not worth it. Other drugs are more in demand, much easier to get, have repeat clientele, and won't put you on law enforcement radar.
Unless there is a confirmed seller in the PPH, or by others on here, anyone claiming to sell N is a scam every single time!
