Viagra - which brand?
I have been trying many brands of generic Viagra and it looks like not all of them work with the same strength. I can imagine that depending on factors like production, honesty of producer and few others, there can be really different amount of Sidenafil in tablets of each producer. We experience the same in steroids where different brands lower the actual doses to earn more.
So which brand is the best in your opinion? Kamagra? Silagra? Retigra? Other?
