Summary
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. Because BDO is a viscous industrial solvent, unreacted contaminants or degradation products may add toxicity beyond GHB's profile. The bitter, chemical taste can mask concentration errors if diluted in sweet drinks, creating overdose risk when sharing containers.
