Drug Checking

GHB concentration varies drastically between batches (typically 0.5–1.5g/ml). There is no safe way to estimate dose without knowing the concentration. Always start with a tiny test dose from any new source. Drug checking services can measure GHB concentration — use them. - saferparty.ch — Swiss drug checking (GHB concentration testing) - drugsdata.org — Lab results database
