I have been using the OPMS liquid kratom shots for over 3 years. They have been very ubiquitous where I live (Jacksonville, FL). It was only about a year ago I tried some of the MIT45 products. When I took the 2 capsule Gold product, I was extremely surprised! I didn't expect much of anything, but without fail, in about a little over a half hour, the traditional kratom effects began to come on. The feeling was more of a energetic super charged energy shot than anything else. It actually took a little longer, but then the euphoric effects began to make themselves known. It was very surprisingly welcome since all I thought I was going to feel was the energetic effects. Maybe it's just me, but the euphoric effects took about an hour or so to come on, and at that point I thought I had already felt all I was going to feel (which was good enough for me). The euphoria was a welcome side effect! Great product!
