They are called Canadian Pharmacy. They sell off brand prescription drugs. I get generic Viagra from them. I have a Drs. prescription, but $200 for 5 pills is too much for my means. I can't say if the drug is genuine or safe, but I've been using it for about 4 years sporadically(as needed) and have suffered no ill side effects. Not advertising for them just telling who they are and what they're about. How they get a specific phone number, who knows. I didn't answer because I didn't recognize the number, but had it written in a note pad as I log all phone conversations to cover my butt for future use if needed.
Please be very careful. They make these drugs in India under filthy conditions, and there is little quality control as to the amount of medication per pill. They are way cheap in comparison to our rip off prices,which really needs to be addressed in this country. And here in the USA its getting worse all the time. You can get coupons for other ED meds on line and use them for free samples,but you need a script from your doctor. I paid $100.00 for my script and my insurance pays $100.00 but I cut them in half so the five last me a long time. Please be careful.
