The device is to be worn for a minimum of 4 hours per day. A sufficient amount of tension is to be applied and initially it is recommended to take a rest period every hour for a couple of minutes. It is not necessary to complete the 4 hours consecutively and they may be broken up to suit your lifestyle and routine. If you are interested in making faster gains you may wear the device for longer periods up to a maximum of 9 hours per day. To achieve good results we recommend Andropenis be used for at least 6 months but if you wish to continue to make more gains you can use it for longer.
