Ok I will start with the good points about this pill. It gives you a tone of energy. I am getting so much done at work and around the house because i can keep going and going...Holy toledo. Also it pretty much completely takes away your hunger. To the point where you have to remind yourself to grab something just to put something in your stomach. The bad- One day I took two pills at once and drank a couple cups of coffee and then felt so sick to my stomach and was super jittery and headachy all day. I didn't want to take any more pills after that, but after a couple days I got over it. The key is don't take any more than one pill at a time and make sure you keep a little something in your stomach throughout the day. I lost 12 lbs in 2 weeks. Good Luck!


This is my first week I am really hoping to get rid of my flabby tummy I hate putting on a bathing suit! So far I have good energy and I am eating less and I am trying to eat better foods. I have not weighed in yet but I really hope this works for me like it's working for everyone else!!

This is the only diet pill that I have tried where I actually liked the way it made me feel. Most times they make me feel nauseas and give me headaches- but not this one- I felt amazing. The weight loss was not huge however, 11 lbs in a month. But for me it was still well worth it.


Less side effects

I used to take Meridia and after about a month it started giving me heart palpitations (not to mention constipation) so decided to stop and try Fen Fast instead because of the supposed less side effects associated with it and I am relieved to be several weeks in and I am feeling very good with NO palpitations and have lost a total of 22 lbs.


You've got to try it

I am blown away by how amazing FenFast has worked for me. I have dropped 15 pounds over the last month. Anyone trying to lose weight should add this to their diets.

4 days and down 5 lbs. I love it I am not hungry at all and no side effects.


Fen Fast

I have been taking Fenfast for 3 weeks and have lost 16 lbs. I also do cardio every second night and then weight train on the other nights. I eat lots of protien and have cut out all refined sugars. This is very easy to manage and I plan to stay on it for another 3 weeks or so and I will be in a healthy range for my BMI.

e. mason

I have been taking fen fast for a month and I have lost 12.3 lbs. I started at 173 and today I weigh 160.7. I was hoping to do a little better then that in my first month, but 12 lbs is not bad. I am almost out of pills I think I should order another month or two as I would like to lose another 20 and get in a very healthy BMI range. I do already look better and my clothes are fitting better.

FENFAST® 375 Proprietary Formula

The FENFAST 375 proprietary formula contains ingredients that are clinically researched to support weight management. These top scientifically studied ingredients include:


L-Phenylalanine is the main active ingredient in the non-prescription FENFAST 375 diet pill formula. This ingredient is very well known and has been carefully studied over many years. It is for this reason, as well as its having been scientifically investigated for effectiveness and safety, that it was chosen to play such an important role in these weight management support tablets.

There have been a number of clinical studies* performed on this substance in order to be able to understand its effects and gauge its safe use. This was a requirement by the developers at Intechra Health when they chose the various substances that would make up each FENFAST 375 diet pill.

L-Phenylalanine is an essential amino acid, which means that the body can use it but cannot manufacture it on its own. When it is supplemented, research shows it can provide greater overall weight loss results than the outcome from a placebo group in research studies. The reason is that researchers have noted that this ingredient promotes the release of cholecystokinin (CCK) and is linked in human studies with reduced food intake. In this way, dieters can eat smaller amounts of food every day as a part of a healthy weight loss strategy. This is helpful in allowing a dieter to naturally decrease the amount that he or she eats.

* A B Ballinger and M L Clark. “l-Phenylalanine releases cholecystokinin (CCK) and is associated with reduced food intake in humans: Evidence for a physiological role of CCK in control of eating”. Metabolism. June 1994:Volume 43, Issue 6, Pages 735–738.


Caffeine Anhydrous

Caffeine anhydrous is a central active ingredient in the FENFAST 375 formulation, which makes it possible for this non-prescription diet pill to provide a wide range of different helpful benefits to individuals who are seeking faster and easier weight loss. This American-manufactured diet pill was developed to produce the same kinds of benefits dieters find the most helpful as they pursue their weight goals without the use of some of the leading prescription weight loss drugs. This ingredient is an important part of this achievement.

Scientific research* has shown that there are several different weight loss-promoting benefits that are linked to the use of caffeine anhydrous. This single ingredient helps to provide the complete formula with a well-rounded arsenal of effects that may assist a dieter in reaching his or her weight loss goals.

These studies have shown that caffeine anhydrous can help FENFAST tablets to provide powerful appetite suppression. This effect helps dieters who are on a reduced calorie diet to be able to eat smaller meals and still enjoy that feeling of fullness, while eliminating the sensation of starvation. This also helps to reduce the experience of food cravings that can lead to excessive snacking.

Caffeine anhydrous (1,3,7-trimethylxanthine) is also a well-known metabolism booster which provides increased energy levels, to make exercising easier and more effective for fat burning.

[1994, 18(5):345-350]



L-Theanine is a naturally occurring amino acid found in tea. Alone, it provides limited benefit to dieters seeking weight loss. However, research shows its potential grows considerably when combined with caffeine, another ingredient in the FENFAST 375 proprietary formula.

One study* showed that when L-theanine and caffeine were combined, the benefits of both ingredients were magnified. Participants noted less “mental fatigue” as a result of the caffeine and they stated that they experienced greater reaction time, accuracy and memory. At the same time, those benefits of caffeine were more stable and less likely to cause the types of side effects sometimes associated with stimulants, such as headaches.

A second study** combined L-theanine and caffeine and were found to suppress fat accumulation while boosting body weight control. They were found to offer additional helpful anti-obesity activities when used in a careful combination.

In order to make sure that the FENFAST 375 formula was able to provide a full range of highly safe and beneficial effects to dieters in a nonprescription tablet, the developers from Intechra Health included theobromine among its ingredients. This specific substance was chosen due to the fact that it is well understood within the medical and weight loss industries following considerable research. It is recognized for being effective for promoting weight loss among dieters seeking to reduce their body fat levels.

Also known as xantheose, theobromine has undergone extensive clinical research*. It is a bitter alkaloid of the cacao plant, which is also often used in high quality weight loss aids and other wellness products. This ingredient is most famously found in dark chocolate.

There are two primary effects produced through the use of Theobromine which are considered to be beneficial to dieters who want to lose weight more quickly and easily. The first is that it has shown to support healthy blood pressure levels and healthy circulation by widening blood vessels. The second is research points to it as a mood supporter in order to assist in the maintenance of a strong motivation level.
