GBL almost ruined my life, dosed around the clock for a month straight, worst WD ever. One time a girl tried to take a swig from the bottle, didn't dilute it, she stopped breathing. We told her old man to take her to the hospital, he was a retard and went to the bar left her in the van instead. She died. Not sure how much she took , but a swig compared to us dosing with a pipette 1.5 ml at a time. Poor girl didn't have a chance. You can definitely OD on that shit, just be smart. I would never touch it again now.
