Adipex is the patented brand name. Phentermine is the generic name. There are many companies that manufacture the generic phentermine. Of course, the name brand will cost more than the generic. Phentermine comes in tablets, capsules, different colors and markings, various milligrams depending on who the manufacturer is. I don't think we are allowed to post where to order Adipex/phentermine via this message board. Just do a internet search for phentermine and see what comes up. Be sure to do the research prior to ordering. Oh, have you tried to get phentermine through your doctor?
