If I like to order a bunch of labware together with sodium nitrite I can not say that I will be making sausage that doesn´t sount realistic, so what should I say?

Act queer and say you need a whole bunch of Poppers.

It is not watched it is not anyones business,order off line people are just glad to a sell.

Don't worry about ordering sodium nitrite. I take it you're using it for making GHB not isopropyl nitrite. Good luck. More input and improvement is needed on that method.
