This is an auto-shipping product, they will charge you each month and ship you the product until you cancel it. We can’t say anything bad about the product, but we generally don’t encourage our readers to take auto-shipping products. Also, you must know that the idea of these supplements is to encourage your free testosterone in your body to be utilised by the vitamins and the herbs in these products. However at your age, there may be not as much free testosterone to be utilised anyway and some of the herbs, vitamins or other ingredients can affect you if you are on a medication or if you have some condition which requires more attention. That is why, at your age, it is best to ask first you personal doctor or a professional doctor before taking any supplement, no matter if it is an all-natural one or not. Generally, if I was you, I would just skip it.
