G can mean GHB, GBL, or 1,4-BD. A small measuring error can cause an overdose.
Check first
Exact drug and strength in mg/mL
Measure with
A marked oral syringe
Avoid mixing with
Alcohol, benzos or opioids
Check the liquid before measuring
Find out exactly what it is and how many mg are in each mL. Ask a drug-checking service if it tests liquids. Use a marked oral syringe once strength is verified. A capful or a number of drops can be way off.
1–2.5 g is a reported range for swallowed GHB. Those are grams of GHB. Skip an unverified liquid. With a verified strength of 250 mg/mL, 1 mL contains 250 mg. GBL and 1,4-BD have different strengths.
Avoid mixing and taking more
GHB and GBL kits screen for different drugs. Neither tells you the strength. Avoid alcohol, benzos, and opioids. Write down the amount and time. Don’t take more if effects are slow.
If you use throughout the day or night, get urgent medical advice before stopping. Withdrawal can start within hours. A seizure or severe confusion needs emergency help.
