Gavin G. reviewed Qualia Mind
Very effective and acts quickly, then lasts all day without a spike or crash.
Good effects but pricey
One thing I noticed is I have a more noticeably effect when I’m actually trying to focus on study or something. But when I doing something active I usually don’t tend to have any “high” from it at all.
