Assay: 99.3% 1,4-Butanediol BDO
More info about 1,4-Butanediol
1,4 Butanediol will metabolize to GHB in a healthy system.
GHB is a wonderful drug with the least side effects (emphasis on the least as opposed to little).
I want to warn about 1,4 Butanediol (aka BDO) though. It is much more addictive and quickly turns from a nice high into something that feels like Benadryl. It’s also the easiest to find in the US. To recognize it, BDO is oily and a drop of it on a table with take a very long time to evaporate (days or weeks). GBL evaporates quickly, and when GHB evaporates it leaves a salty residue.
