5/5
I initially received a free sample of Cannibal Genius, but was impressed enough to go ahead and order a full bottle. It complemented the other supplements I was taking and didn't cause any degree of discomfort except when combined with higher dosages of rauwolscine. I found it to be helpful in increasing focus, improved retention, a better presence of mind (I noticed a greater degree of metacognition), and it helped with cognitive fatigue to a degree. Of additional note, the general grogginess I get from noopept alone, even when taken with choline, was absent likely due to the other constituents of the formula. I didn't expect anything miraculous when taking it, but I'm pleased with the benefits it provides especially for the price.
