Short description of ULTRAPENE 3.0: Penis enlargement exercises are designed to break down the cell walls of the Corpora Cavernosa by forcing blood into them, each time this stretches the cells larger than normal. The penis then repairs itself by growing these cells back, larger and stronger each time, this allows the penis to hold more blood which expands the erectile tissue and over the course of a few weeks, results in a larger, stronger and fitter penis.
