Wow I'm surprised I found Nembutal on the dark web so easily. Its expensive but its sold with escrow on a legit marketplace so it could be real. Interesting. I know everyone here will probably insist its fake but never underestimate the power of the dark web.
You might find this interesting.
I watched a documentary about one of the first right to die organizations in the US. There protocol used to be 10g of Nembutal.
The problem is that once much safer benzos hit the market, doctors basically stopped writing prescriptions for barbiturates = no demand. The only markets still using the drug were basically right to die organizations and prisons, where it was used as capital punishment.
The corporation that holds the patent then decided that they didn't like the idea of their products being used to end people's lives. This left only right to die, which, in the grand scheme of things is a teeny, tiny market - ie., not worth tying up manufacturing to produce something that has no demand.
Because of this, the price skyrocketed - by like several thousand dollars. The right to die organizations then switched to Seconal - another powerful barbiturate, however this too became scarce because benzos are much safer to prescribe.
The bottom line is Nembutal is hardly even manufactured anymore. Furthermore, if the legitimate price is several grand, the black market is going to be ridiculous.
While not impossible, the probability that someone is selling Nembutal is very high that it's most likely a scam. Drug dealers are in business to make money - there are far easier and more lucrative drugs to sell and obtain - they aren't going to bother with something that virtually no demand. Let's face it, other than people looking to ctb, I highly doubt even 1% of Drug seekers on the dark net are searching for Nembutal - it's a niche drug now - people aren't looking for it - they are all searching for xannies or other more popular substances.
