Viagra on the beach

I like to travel to South East Asia to dive so I spend plenty of time down the beach. Any one familiar with South East Asia is aware that pretty much everything is unregulated and for sale. So when I am constantly approached on the beach and propositioned to purchase Viagra, I ask myself, does anyone really purchase drugs from a guy on the beach?

My knowledge of Viagra is pretty rudimentary, Pfizer was developing a blood pressure and angina drug when they noticed some unusual side effects during human testing. Apparently you need to firstly visit a doctor where I guess they measure your blood pressure along with some other tests whilst reviewing your medical history.

So I have to ask, who I purchase pills off a guy on the beach that has the potential to kill me? We have never got as far as discussing price but I do wonder what the expected savings are? Ok, so I don't need to pay for the medical consultation and I imagine the pills are discounted. Pfizer is a major international drug company producing drugs for medical professionals, hospitals and clinics.

I seriously doubt Pfizer would be developing a grey market for pharmaceuticals and I am guessing these pills would be fake. So I have to ask myself, would I be popping fake pills with the potential to kill myself? Surely, no rational person would actually buy these?
