YES! Dude look for mold. If the color is weird or theres a white layer anywhere in ontop of it. DO NOT take that. You keep that in a super tight container, and you don't let it sit somewhere for too long especially if not taking freezer is best place if you save g, but you never know unless your mailman is delivering what form it is gbl BD, it should freeze at a certain temperature, true, pure ghb. : ) I just cannot remember what freezer storing temp was....

It should be fine though if there no white layer or any discolored particles in the liquid and it looks and tastes the Exact same they its good. I never let that set around for more than 2 or 3 weeks. Its an odd substance you should be um aware of, and have a common knowledge on the chemical. Its easy to OD. SO easy I dunno why more people use pills than that. You wouldn't feel pain for but a min then you gone under. Its happened to me and it was because I'm dumb and forgot tolerance never matters witht hat shit unless youre a ghead lol. For real. This drug especially always be careful and dont be leaving it in weird places fool. Jeezzz waste! 
If it was LSD it would be ruined.
