I'm the pro. about real and generic viagra...
if you have a stop in BKK , buy it in BKK..
Very cheaper than Phuket
I buy generic viagra.like : Penegra 4x 100 mg for 700 baht..in BKK
Reallly not bullshits.. same effect.
Enough power for a whole week with that.( cute in half)
In any pharmacy around Sukhumvit area
In Patong the cheapeast i've found is Karmagra : 4x 100 mg for 1100 baht.Same effect
Real Viagra cost about 500 baht for 1 x 100 mg in Patong.
