That is a good question Chongo. Looking at the site, they frequently use the copyrighted names of Cialis and Levitra, but they never use the word Viagra. Why would they say ‘generic Cialis” but then Generic ‘Sildenafil’ instead of viagra?
As for brand name Sildenafil, there is only one REAL brand name and that is Pfizer’s Viagra. If they give you anything else, that would be very misleading. (For example to send you Indian branded Silagra, and call it a brand name). So I would guess that the brand name stuff is Viagra, but it is wierd they don’t say it.
On the other hand “brand name Cialis” can only mean one thing.
