when phen stops working?

[amberc4614]

does anyone in here take phen under any other name than phen? i have been doing some (limited) research on bontril and found it listed as
phen on a couple sites. i am also looking at the phen-pro cocktail. i am just trying to learn right now but ever since i started back on
phen the 37.5mg i used to take it TOO much (caused insomnia) and the 30mg isn't doing anything for me. i have also heard of phen being
mixed with xenical. has anyone else heard of these or tried these? interested to know. thanks!

Bontril generic name is phendimetrazine so it's a lot different than phentermine. 2 totally different products. I know it sounds the same & I don't know the difference. The only thing I do know is that Bontril is newer & Phentermine has been around for a long time.
