I’ve been a Green Hippo fan from the beginning and have tried pretty much every strain. Never thought much about nootropics but they included a sample of this stuff with one of my shipments of kratom and I tried it. WOW. On my second bottle now and it’s working just as good as the first. For those who are unaware of what nootropics are or what this does, it gives you about 6-8 hours of smooth sustained energy, better thinking power and euphoria. It’s pretty cool for work and for going out.
