When an ER patient administers Vidalista 20mg tadalafil pills, he incorporates CGMP into the body. As the level of CGMP increases in the body, it challenges the activity of PDE5. When the volume returns to the normal level, the muscle cells give way to blood flow in the genital supply tract, causing a stronger erection. Vidalista 20mg is usually taken as an oral dose of one tablet, usually with a glass of water. It is compatible to take the recipe without food or on an empty stomach for best results.
