It’s illegal to purchase Kamagra in UK, USA and all around Europe. If you are caught buying any illegal generic medicines, you might end up with either heavy fines or even prison. Are you prepared to do that?
The only place where you are allowed to buy Kamagra, a generic version of Viagra, is in India. India have different patent laws and they seem to be able to get away with copying pharmaceutical ingredients without any legal actions. Same is true for parts of China, where Kamagra or similar versions of generic sildenafil also can be bought over the counter.
If living in UK, remember there are many legal alternatives to Kamagra, such as HealthExpress or EuroClinix. However, they only sell genuine medicines and no counterfeit or illegal products such as Kamagra.
