I received some ketamine that I've tested with a Morris DCK/Ketamine reagent test, and it seems to check out as Morris purple. However, there is something different about this batch compared to other ketamine shards I have tried. I typically only microdose around 20-30mg 2-3 times a day, but I wake up with a pounding migraine and feelings of depression after taking this ketamine. This is a new experience for me, as I have never had these symptoms with such a low dose before. I am aware of the ketamine hangover, but I am starting to wonder if this batch may not be pure ketamine. I also take an SSRI and have recently started taking prescribed modafinil. Although ketamine has never negatively interacted with the SSRI in the past, I am concerned that there may be impurities or other substances causing these adverse effects with this non-pharmaceutical grade ketamine. I am wondering if there is a better reagent kit to test for impurities, if this is something I should be worried about, or if this is a common experience.
