Primal Grow Pro Exercises do not cause side-effects. Because this method is 100% natural, the routines you do are very safe and gentle, and because you are only using your hands to do these exercises, you don’t have to worry about getting side-effects. The only way you get side-effects with penis exercises is by not following the guide thoroughly, doing exercises that you don’t find in a reputable program, doing the exercises longer than what is recommended, or not using natural lubrication for the exercises that require it.
