This was one of my very first concentrates tried ever before. 9 times out of 10 when I used this, I would feel brighter and more motivated. Like I had a nice cup of strong coffee. Rare times, it did nothing to pick me up from dragging ass. Overall, I like it. I even turned one of my good friends on to the product. She's afraid of THC...and she loves it as a mood Lifter. Overall would recommend.
