so whats the general consensus on GBL, a fun party drug thats very easy to slide into addiction with?us americans are stuck with Bdo...ive never done Gbl but from whats been said, the high is more intense than Bdo but doesnt last as long, maybe an hour tops?is this true?surely Gbl sticks around for a few hours right?
BDO/1,4-Butanediol is a GHB prodrug that works in the traditional way - a slow conversion to the target drug, resulting in a longer duration, but a slower onset with less "kick" to it. GBL is also a GHB prodrug but interestingly enough it actually absorbs and converts to GHB in the stomach much quicker than GHB itself is absorbed when eaten, so actually has a faster onset than GHB itself, with a harder kick too.
So in terms of strength and duration:
Initial peak and overall strength at a similar dosage:
GBL > GHB > BDO
Duration:
BDO > GHB > GBL
So depending on which you prefer you can choose based on that, though it's worth bearing in mind that BDO metabolises in a similar manner to alcohol and so is toxic to your liver in a similar manner. GBL is virtually non-toxic but if you really
REALLY overdo it and consume huge amounts you can end up with your blood pH raising and causing metabolic acidosis. GHB is almost entirely physically non-toxic and doesn't really cause any strain on the body - however all three of them are quite addictive when overdone, but yeah GHB > GBL > BDO in terms of safety.
As for dosage and duration, in my experience GBL lasts 1.5 to 3 hours depending on the dosage, setting, whether I've redosed etc, and 1ml of GBL is supposed to convert to between 1.4g and 1.6g of GHB and has a similar overall intensity (but a slightly more intense initial peak in my experience than an equivalent dose of GHB).
GHB lasts around 2.5-4 hours depending on the dosage, setting, redose frequency etc, sometimes even a tiny bit longer. Now the dosage conversion I gave above works both ways but as I said above GHB has a slightly less intense initial peak/kick to it, so I find for example if I want a similar initial "rush" to say 1.5ml of GBL, rather than taking 1.4-1.6x 1.5ml (aka 2.1-2.4g of GHB) it's better to take a little over that, like 2.6-2.8g, though the rest of the high will be stronger as a result, not just the initial peak, since GHB doesn't have the initial rush with a drop off that GBL does and tends to stay more stable throughout.
Hope this helps, I didn't mention BDO duration or dosage because I don't have experience with it and while there's dosage/duration info online I've found my own experiences to vary from that with GBL and GHB already, so I'm not sure how accurate it is.
-----------------------------------
To the person asking what to dose the first time with GBL, my advice is to start with 0.7 or 0.8ml. To most people, myself included, that seems like a crazy small starting dosage, but basically that's the lowest dosage I've found that anyone has found to be strong - with a few of my friends not really enjoying higher doses than that, so I figure it's a good starting range for anyone to work up from.
That said if you already have some tolerance to: alcohol, benzos, barbiturates or any other GABAergic, or aren't super skinny, then I'd aim for like 1-1.2ml as my starting dosage. If you have quite a high tolerance to GABAergics and/or dopaminergic stimulants, or you're on the heavier side and typically need a lot more of most drugs than others, then you might even want 1.3-1.4ml to start, but even if your tolerances are sky high I'd never recommend starting higher than that since if your G is top quality and you end up being one of the sensitive people even 1.3-1.4ml can be a very strong experience. For me 1.4ml is actually my perfect initial dose for a night, though I redose once every hour or two with a slightly smaller dose than before.
