Sildenafil citrate, the primary ingredient in Super P Force, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for the degradation of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the penis. By inhibiting PDE5, sildenafil citrate allows for the accumulation of cGMP, leading to smooth muscle relaxation and increased blood flow to the penis, resulting in firmer and longer-lasting erections. https://www.powerpillss.com/product/super-p-force/
