Purchasing Viagra Online

I recently purchased Viagra online from a website called *****.  I recieved a trial pack and am pleased with the results.  It worked and everything, But I am curious.  Are there any serious side effects I should know about? especially when I purchase it online rather then a prescription from my doctor?

read about side effects on a google search. any health concerns ask your Dr. why do i get the idea your to young for this. if young you might need something else your deficiant in. dont be shy ask a Dr.
I saw a show on tv that said the online cialas was made in china out of cardboard.
Sounds like yours is legitimate. good luck and take care.

i bought a sample pack on line from a CANADIAN pharmacy and there were poor results. the  viagra and cialis samples were useless. i went back to my local pharmacy and both worked as usual. i called the customer service number and was repeatedly disconnected. it was a scam!
