Only tried their Jetpack Kratom gold extract tincture. I treat myself to a bottle every once in a while or if I'm going away or going to a concert and need a discrete and simple way to dose. It's very strong but It's a much cleaner high. I took too much once and Couldn't keep my eyes open because everything was spinning, but there was no nausea at all, and I still felt amazing once I lay down in a dark room. The same amount in doses of powder would have me sick as a dog.
