I purchased some several years ago over the internet from Low Cost Pharmacy in Tempe, AZ. There are probably plenty of internet pharmacies that you can buy it from. But it's much better to buy it from a U.S. pharmacy.
It comes in 20 mg tablets, which are intended for someone with severe ED who can't get it up at all. If you're taking it for "recreational" purposes, i.e., a little bit of a performance boost, it's better to try a much smaller dose. You will have less in the way of side effects and save money.
I never take more than 1/8th of a tablet, and the effects seem to last longer than 36 hours. |
