So I tried the Krypto last night and holy cannoli. That stuff is potent. I was ripped for a solid 2.5 hours. And that's just out of a little bowl. I might take a couple bong rips and see how it goes later today. Afterwards, I ate any and everything I could get my hands on. I already planned for yesterday to be a cheat day so who cares. And then I fell fast asleep and slept really well.
So, conclusion is, this stuff works, it's pretty strong (especially the Krypto), and legal. How can you go wrong?
