Question: what is the difference between viagra and spedra?
Answer: Compared to Viagra (Sildenafil), Spedra is significantly faster. Spedra starts to work in around 30 minutes and in some men it may work as quickly as 15 minutes! Viagra on the other hand needs to be taken one hour before sexual activity. Spedra remains effective for four to five hours, which is similar to Viagra.
