Hey, so I have some GBL sitting in a plastic bottle that I've had for about 7-8 months. Its just been sitting on a bookshelf, out of direct light. I tried some the other day, after not taking any for at least a few months, and it tasted MUCH worse/MUCH more bitter than any of the other times I've taken it. I know GBL doesn't taste great to start with, but it's noticeably much worse tasting than I remember. It is possible that a significant amount of plastic has leached from the bottle, and that's why it tastes so bad? Or is it possible that the GBL has gone "bad" in some way? Either way, do you think it's still safe to consume? Thanks.
