A friend of mine visited a "head shop" in Dublin and purchased "Chinese herbal viagra" over the counter. He has used the real thing before and siad that there was no difference (i.e. the herbal viagra worked just as well). However, I month later he went back to buy more only to be told that it had been removed from sale (he was then offered it under the counter). I cannot say where exactly, for obvious reasons, but it was in Dublin. I don't condone the use of it though ... for the health concerns disussed above. I would not consider ordering it on-line for the very same reasons.
