    Summary TheDrug.Wiki Erowid TripSit PsychonautWiki

    1,4-BDO is a prodrug for GHB, metabolized by alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). Individual metabolic variability means two users can respond very differently to the same dose. Onset is slower than GBL, making redosing particularly risky as people often mistakenly believe the first dose was weak.

I felt pretty good about trying it. The first time IΒ’d read about this niche drug was more than 20 years ago.

    I donΒ’t normally feel inclined to write on forums, I read them, make a judgment and act. Heck, often I already know what I want to do, but I read the articles for that one out of thousands that conforms to what I want to do and itΒ’s settled.

    After much trial and error, usually accompanied by an overwhelming sensation of riding a psychedelic tilt-a-whirl, like being too drunk, but a bit more lucid (so you can think about how stupid it was to drink a second helping), I have arrived at 5ml of 1,4B stirred into an 8 oz. glass of citrus juice as the right mix.

    Not Sleepy, But Fun neutral exp #6747

    I heard about 1,4 while searching for a non prescription sleep aid that did not interfere with the natural stages of sleep. Indirectly I found out that 1,4 was used recreationally and a larger percentage of it activates the natural production of GHB in the body.

    After having heard a little on the radio about the new 'legal' form of GHB floating around the market in Australia I did a little research and was surprised at how easy it was to obtain two litres of 1,4 Butanediol for a very reasonable price.

    1 4 Butanediol And Insomnia cautionary

    Fuck that shit! I'd recommend staying away from it. I've been experiencing difficulties with going to sleep and especially sleeping through the whole night for my whole life. So I bought a bottle, took 4.5ml first day - felt good. Slept good. That's what I bought it for.
