Product Description : Kamagra expands the arteries in the penis and thus allows filling of blood into the sinusoids (small spaces in the penis). It results in hardening of the penis, and the veins bringing in blood are then compressed restricting the flow of blood out of the penis. This entire procedure results into sustainable erection. Research has shown that four out of every five men taking Kamagra showed an improvement in their erectile function regardless of their age or the length of the period for which they were suffering from ED. The recommended dose is 50 mg, taken as needed, approximately 1 hour before sexual activity. Based on effectiveness and tolerance, the dose may be increased to a maximum recommended dose of 100 mg, or decreased to 25 mg.
