Viagra is a generic version of the very safe and effective Viagra. Viagra has helped literally hundreds of millions of men better their sexual performance through the achievement of stronger erections, that will last for the duration of sexual activity. The active ingredient in Viagra is sildenafil citrate, and it also the active ingredient in the original Viagra. Sildenafil citrate is present in the same proportions in both the generic Viagra, Suhagra, and the original Viagra. Viagra is a chemical replica of the original, and will work exactly as well as the original. The only difference between Suhagra and Viagra is the price. Suhagra will cost a fraction of the 10$ and up a pill that Pfizer is currently charging for Viagra.
