Safety of purchasing GBL from Europe

[Black Death]

Almost sure that 1,4 BDO is broke down in the liver, and GBL is broke down in your stomach.

 

[ChemicalReaction]

I beg to differ that gbl in H2o will give a concentration of 78%. Gbl alone is not exactly anhydrous to start off with, therefore if your claims are true there would already be minimal amounts GHB within the initial mix. GBL converts to ghb in your system due to the acidic values in your stomach.
If one trully wanted to you could drink GBL straight and get the same effects.
