Vidalista 80 contains 80mg of Tadalafil. This is a very high dose and for 95% of the users NOT adequate. This dose is not for beginners!
As a beginner be sure to start with 5mg per dose and increase from there slowly (if the wanted effect is not achieved). If you take more Tadalafil than your body can take, it will only increase the side effects but not the quality of your erection.
Please note: the picture is an old example picture. The packaging and name of Vidalista 80 has been changed by now and the pills are not black anymore but yellow.
