Should i try weight loss pills?

my brother is into body building and is a fitness instructor. I am the complete opposite i am over weight he has suggested some weight loss pills called EPHEDRINE.I have looked on the net see a few side affects that don't seem to bad but like any drug they have side affects. I have started to eat healthy by this i mean high fibre,low fat food like veg white meat,fish,fruit and whole grain pasta instead of white and started to exercise 4 times a week .i am really tempted to try these has anyone tried them before? he said they really do work and quick
