I could call 3 people right now who could make GHB....it is not hard for someone with minimal chemisty knowledge.
At the front end, acetylene and formaldehyde under very high pressure to make 1,4 butanediol (high energy Reppe chemisty: the Feds know all about this).
This is equipment found in petroleum sites, like a refinery.
I suggest you submit the names of your 3 people to the FDA because they are certainly on a list and I question your intellegence on the matter for that reason.
