??PhenD/Bontril While on Cycle

First off...I know some of you have probably heard of PhenD, Bontril and Phenterfien as diet pills or more less appetite surpresents. Ive heard both good and bad but nothing that included AAS

Questions:
Has anyone used them while on their Cycle?
Are they effective in cutting?

I am currently on Tren/Prop/Winn/Clen.

Thanks for Input!
