Bought this product and tried it out. Been hearing about for years on the joe rogan podcast so I was curious.
I give it a 7.5/10. If you work at a desk it definitely makes it easier to focus on tasks that need your attention. I was using it to write sales scripts and again it definitely works. Time would just fly while getting shit done.
The only drawback is the fact that it costs $50 for a two week supply. I can find better supplements that use the same herbal ingredients with ease. Hard to say which ingredient it is exactly that makes the difference but these companies all copy each other regardless so it isn't hard to find a similar mix.
Definitely recommend it for anyone curious that's looking to try it out.
