where in the world can the US banned diet pills called "phen-phen" be
purchased? and can they be legally shipped or mailed here for personal
use?

"phen" is short for phentermine and "fen" is short for fenfluramine. i
don't know where you can get fen-that's the one that was banned. but
phen is still legal and available anywhere. i even ordered it online.
i have lost 70 pounds,i took phen for 2 months to get me started. and
i have been going for a year with only 10 more to lose. it's a magic
pill if you ask me.

thanks!!
