This is a pretty good booster to my energy and stamina. It helps with a lot of things. It gives me better energy with my wife and also just to do things around the house. It even kind of helps in the gym. I'm not sure if that is just a placebo effect or not, but regardless, it is a pretty good product. My only complaint is the price. I don't really think the cost is reflective of the results. However, it is still a good product. I would probably tell my friends to use this.
