Butanediol

A guy a the gym asked me if I could get him some Butanediol. I'd never heard about it. Apparently it's a liquid used for cleanig industrial machines. 1liter=3.8gallons costs about $1.(He got it eventually from a cleaningfirm) He's planning on drinking that on his next cycle. Anyone heard of this before? Looks like I'll have to buy him a tombstone for Christmas.

Synonyms: Butanediol, butane-1,4-diol, 1,4-butylene glycol, 1,4-dihydroxybutane, 1,4-tetramethylene glycol, butylene glycol, tetramethylene 1,4-diol

What is this? ANyone ever heard about it?

it is an anologue of GHB - do a search on it - it is a little rough on the kidneys if taken a long time but it isnt particularly bad. It has a longer action than G alone and lasts around 6-7 hrs - good for a buz and sleep - BB?, not really.
