What fat burners can i take with phentermine ?

Be VERY careful: I'm not a bariatrics specialist, but on general principles i'd caution against taking any fat-burner (which may have effects that mimic the sympathetic nervous system) with phentermine, which is also tied up with catecholamines. I am glad you are trying to lose weight and wish you the best; my strongest hope is you'll find a group of friends who are into aerobic fitness. Good luck.

None: There are no legitimate "fat burners" except physical exercise. Stop wasting your money, get on appropriate diet and exercise; get support from programs like weight watchers. Phentermine only helps as long as you're taking it, and then you regain the weight. You need to find how to eat properly for the rest of your life, not the next month. Don't get your medical info from friends, tv or internet.
