Till now, Viagra is considered to be the best erection pill which is ruling the market. But after the year 1998, Cialis was launched which became a high success in the world market. This product was launched by the ICOS Co. which tried to shatter down the success of the Viagra.

Cialis is known to be the performance enhancer product, and deals with the regular problem of non-erection. The mechanism behind these products is that they block the special enzymes of the body because of which our body feels relax and muscles get rest. As a result, there is growth in the muscles of the penis which increases the sexual cycle of a man.

The best thing about Cialis is that it is available in all the big countries like Australia, Sweden, Finland, Denmark and United Kingdom and also getting approved in the USA also. Another reason behind the popularity of this product is that it provides fast results as compared to Viagra. The initial stage can be achieved in just a time period of 16 minutes after consuming the pill, while the whole effect can be seen in the whole day, whereas in case of Viagra, the effect retains only for 4 hours a day.
