nbsp I heard Fen-Phen was no longer available because it causes heart problems?
A.  You are referring to the prescription drug combination Fenfluramine and Phentermine (Fen-Phen). This combination is no longer available because it did cause heart valve damage. Thermo Phen Phen is NOT Fen-Phen and is NOT a prescription drug. Thermo Phen Phen is 100% Natural and contains five herbal ingredients that have been proven effective for weight loss. The Phen Phen in the name Thermo Phen Phen refers to the 200mg of Phenylalanine, which is the ingredient that puts Thermo Phen Phen ahead of all the other natural weight loss products. The only similarity that Thermo Phen Phen has to prescription Fen-Phen is that it will work in a similar manner. Both products speed up metabolism while simultaneously controlling appetite, which is a very effective formula for weight loss.
