I've used several USP products over the years. I have never had very much success with their products. They do write the best hype articles in the business however. Powerfull has been on the market for a long time and has a number of positive reviews so I thought it might be worth a try. From my experience, it is a great sleep aid but thats about it. I didn't have better pumps or more vascularity or gain any additional mass or get more cut. But when taken before bed I usually got a great nights sleep. Moreover, if taken too late in the evening or in too large a dose I was usually groggy the next morning. So if insominia is a problem this is a great product in my opinion. |
