I recently got to know Nootropics when i stumbled upon https://newmind.com
I think Nootropics are generally really interesting and potentially have a bright future in the health/Lifestyle-industry. Now im looking for proper investment oppurtunites. Any ideas?

You could also try something like Hordenine. Hordenine is a natural supplement which is avaiable for a long time now, and it is also sold by respectable vendors like Liftmode: https://liftmode.com/energizing/hordenine.html
Hordenine helps me to stay motivated for doing sports and mainiting a healthy lifestyle.
