One should calculate the dosage properly to get the utmost benefit from Cialis. This is one of the main concerns for those who buy Cialis online without prescription. Patient usually begins his treatment with 10 mg Cialis pills. This is the optimal dose that suits the majority of men. Person can increase the dose and acquire 20mg pills or, on the contrary, decrease it to 5 mg pills. Do not split the pills. Patients should take whole tablets to make sure that there is no mistake.
