The FastSize Extender is a relatively safe and easy-to-use device that aids in penile enhancement -- in terms of length and girth. It uses the principle of tensile force and the body's natural ability to adapt under such influence. By exposing to a regular and durable traction, the cells in the penis chambers begin to divide and multiply, thus increasing the blood flow to the penis, ultimately increasing the tissue mass.

With continued use, this process allows the penis to hold more blood than it could before. As a result, you will notice enlargement in both length and width (girth) of the penis.

The penis has three structures: a small chamber in the bottom (the Corpus Spongiosum) and two large chambers on the top of the penis (the Corpus Cavernosa). There are spaces within these networks of tissue. So that when the penis is flaccid (or in a resting state), the tissue is condensed and the spaces are reduced. However during erection, the blood streams into the chambers causing the penis to be enlarged, hardened and likewise elevated.

During erection, impulses from the local nerves and the brain (brought about by sensory or mental stimulation) cause the muscles of the Corpus Cavernosa to relax, allowing blood to surge in and fill the spaces. The blood creates pressure making the penis expand. The trapped blood in the Corpus Cavernosa is what sustains the erection.

The amount of blood that the penis chambers can hold determines the size of the penis. Thus penis enlargement can be achieved by expanding the actual blood-holding capacity of the chambers. These chambers, in turn, can be increased and developed resulting in positive gains.

The FastSize-Extender can be used at any time of the day for various time intervals, depending upon you. It is unnecessary to wear the FastSize-Extender for a long uninterrupted time to see the outcome. You can likewise take a break for a period of time without diminishing the final result. Refraining from using the FastSize-Extender does not necessarily result in "losing" part of the enlargement already "gained."

The result depends on the overall amount of hours the FastSize-Extender is worn, combined with the amount of traction. It may be worn at night but may become detached from moving around. Thus, it is recommended to use the Protection Pad or other form of protective measure when the FastSize-Extender is worn at night.

Penile enlargement will continue as the treatment continues, however, there will be a point that your body reaches its fullest potential and can no longer increase in size.
