Apply a liberal amount of Shock Therapy Electro-Sex Gel to the area of the body you want to stimulate. The gel magnifies the intensity of the electrodes and provides maximum conductivity between the skin and the Shock Therapy accessories. Eliminates "hot-spots" and works with both adhesive pads and other Shock Therapy plug-in accessories. *Lubricants are a natural addition to electro stim toys as they are needed to completed the circuit between the toy and skin, and also help avoid skin irritation. Water based lubricants are recommended based on their high ability to conduct electricity. Silicone is a natural resistor and is not recommended. Please note: We do not recommend using the Electro Sex Gel internally as there is no added benefit. The Gel is intended to be used externally on the skin to provide maximum conductivity between the skin and the Shock Therapy accessories.
