Hello everybody. I would like to give you some tips on buying generic Viagra. Their effect is no different from standard drugs. You will be surprised. This is because they are based on the same substance. Thus, these medicines have their advantages and disadvantages. Basically, they are bought only at the expense of cost. The price is much lower than the original. Perhaps you did not know that a lot of money was spent on production. For generics, the situation is different. Because they were released for a long time. And technology exists, development costs are absent. Therefore, the final price will be much lower.
