FENFAST 375 Formulation of 100% Scientifically Studied Ingredients*

When combined with a healthier diet and more physical activity, FENFAST 375 diet pills can help dieters to take the steps toward dramatically reducing their weight and excess body fat while promoting a much more healthy lifestyle.*

The FENFAST 375 formula contains ingredients that can aid in fat burning, resulting in more fat and calorie burned, even when you are at rest. Furthermore, FENFAST 375 ingredients help to shrink the appetite, and when combined with a healthy and nutritious diet you will consume less food and considerably slash daily caloric intake without having to suffer the dreaded “starvation” feeling that is common with dieting.*

The formulation for FENFAST diet pills also includes ingredients that help to boost energy levels. This helps to provide the energy needed to complete daily exercises, as well as the motivation to keep going and know that even though it may take several weeks or months (depending on how much weight needs to be lost), you’re getting there, and you’re committed to losing weight better than ever before.*

FENFAST 375 is manufactured in the United States with only the highest quality standards and ingredients. These ingredients, which have each been scientifically studied and found to promote weight management benefits, include: Beta Phenylethylamine HCl, Caffeine Anhydrous (1,3,7 Trimethylxanthine), L-Theanine and Hordenine HCl.*
