Huperzine A works to increase my cognition, focus, and alertness. I have experimented with it when I was ill for a boost, it helped me 3-4x a week at 80-150mcg for approx. 2 months. After this, I recovered from illness and did not use it for a year. I am now in studies and tryjng to avoid caffeine, as it has too many downsides, so I tried Huperzine A again. Multiple times, at dose of low as 40mcg to 100mcg, and without fail, every time, the next day after, I get hit with an intense depression, anger, and malaise directly proportional to the dose. It is really bad.
So caffeine is out, huperzine A is out. I am honestly a little afraid to try other nootropics because I have no idea how I will react. I was considering trialling Piracetam but maybe it would have similar negative effect? I do not know. Maybe these class of drugs are not for me.
