Dietary Supplements and Pills – Penis pills usually don't hurt you but they cannot increase the penis size. Their effect is simply a myth spread by marketers to make money. If penis pills really worked, we would also have pills for increasing (or decreasing) other parts of the body. This is simply absurd.
Penis Stretchers and Penis Extenders (sometimes also called penis traction devices) apply continuous stretching force to your penis. If you follow instructions, they are much safer than surgery and since they employ simple physical principles, it can be easily shown that they really work. It can be worn for many hours, but the ideal period is 2-8 hours each day. The effectiveness of the traction device is determined by the number of hours you had it on and not by the gap between usages. The traction device enables your penis tissues to increase the number of cells through stretching. A good, medically tested product is usually completely safe.
