GHB / GBL

1,4-Butanediol (BDO)

Street names: BDO, 1,4-B, butylene glycol, One comma four

⚡What it does

  • Body converts it to GHB within minutes — sedation, euphoria, disinhibition, libido increase
  • Onset 10–20 min, duration 1–3 h — even shorter than GHB, driving constant redosing

⚠Key risks

  • Narrow dose window identical to GHB — millilitres separate fun from coma
  • Industrial-grade product: purity and contaminants unknown
  • Dangerous dependence builds fast with daily dosing — withdrawal can be life-threatening (like GHB/benzos)
  • Frequently mis-sold as, or substituted for, GHB

✚Overdose signs

  • Sudden unrousable unconsciousness
  • Slow or irregular breathing, gurgling
  • Vomiting while unconscious — aspiration risk
