Oh man.. this is from the website he has linked:
Ayurvedic Urea is strictly restricted to the following:
a) HIV AIDS infected victims.
b) Anyone under 13 and above 45.
c) Dwarfs.
LOL
D) any one over 12 and under 19
E) any one over 18 and under 32
F) anyone over 31 but under 43
G) for the people age 44 and 45 if you are an air breathing human we are sorry you are restricted too
Anyone else it will work on so come and get it
Don't forget that you will grow a couple inches, unless you're a dwarf. It doesn't work on them
If you're young it doesn't work, if you're old it doesn't work too. It works only in special circumstances.
He should restrict it to people between 18 and 22, you're actually still growing at that age so there's a chance you'll get taller and claim it was thanks to this magic medicine, and you'd still be legally able to decide for yourself, so there's no lawsuits from angry parents!
I wouldn't be amazed if he managed to sell it. People are paying for penis enlargement pills, so why not this shit?
