I recently came across this as a "prodrug" to GHB that's legal and freely available. I just ordered 20 grams and will tread carefully, first trying 0.10mls and going upwards. I believe it's 4-acetoxybutyrate and could be active on its own as many acetoxy esters likely are given subjective and anecdotal information. Does anyone else have any experience with this substance?
 
I tried it. Smells strongly of vinegar. Came of crystalline waxy flakes. Dissolves into a 1 gram per ml solution with tap water. Dissolved well. Effects on par with ghb. Dosage i ended up at was 2.5mls and got similar effects to ghb.
 
Very cool. How quickly did it hit you?

Damn, I miss the old days of blue light. This thread would have surely been bumping. Sad days…
