FenFast® 375 tablets are among the best non-prescription pills that are currently available as alternatives to the leading prescription diet pills, including Phentermine 37.5 mg (also known as Adipex). This may seem like a bold claim, but it is one that Intechra Health Inc. has been proud to make after successfully replicating the type of benefits produced by the drug, but in an over the counter tablet.

The developers at Intechra Health dedicated themselves to coming up with a product that would be able to match the types of effects that the drugs produce, but without also causing the drawbacks that have been associated with those prescription medications and that cause them to have to be controlled by doctors.

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.

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.

After all, these scientists understood that there had to be a way to come up with a diet pill that would produce powerful weight loss promoting advantages, such as a suppressed appetite, a higher energy level, and a faster metabolism, without having to suffer from severe side effects or withdrawal symptoms following an addiction.  After their hard work and research, they proved themselves right.

FenFast® 375 is made of a proprietary formula that includes L-phenylalanine, caffeine anhydrous, l-theanine and hordenine HCl.  These ingredients have each been scientifically studied.  Their effects and their safety is well known throughout the medical and weight loss industries.  When properly combined – as was done by the creators of this nonprescription tablet – the benefits can be achieved very effectively, but also very safely.

It is for this reason that many dieters consider this to be one of the ideal alternatives to having to use prescription diet pills.  Of course, FenFast was also designed to help dieters to take control over their own weight loss.  Not only does it produce benefits that allow your body to burn through fat more quickly, but it is meant to work with a reduced calorie diet and a regular exercise program so that you will be able to accelerate your weight loss beyond anything you have experienced before.

FenFast puts you in the driver’s seat of your weight loss program.  It eliminates the discomforts typically associate with healthy dieting – hunger, fatigue, and stubborn fat – so that you can get the very most out of all of your efforts.  In fact, the more you put into your weight loss, the faster you’ll lose.

Therefore, it’s recommended that you start your FenFast 375 program by speaking with your doctor about the best way for you to eat and exercise to lose weight.  With this strategy, you’ll be losing weight in as little as three days.

FenFast® 375 Proprietary Formula

The FenFast proprietary formula contains ingredients that are clinically proven to assist weight loss. These top nutraceutical ingredients include:


L-Phenylalanine is the main active ingredient in the non-prescription FenFast diet pill formula.  This ingredient is very well known and has been carefully studied over a number of years.  It is for this reason, as well as its high level of effectiveness and safety, that it was chosen to play such an important role in these nutraceutical tablets.

There have been a number of clinical studies* performed on this substance in order to be able to understand its effects and ensure 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 diet pill.

Phenylethylamine is an essential amino acid, which means that the body can use it but cannot manufacture it on its own.  When it is supplemented, it can provide greater overall weight loss results when compared to the outcome of 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.

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-made diet pill was designed to produce the same kinds of effects that are achieved through the use of some of the leading prescription weight loss drugs, and this ingredient is an important part of this achievement.

Scientific research* has shown that there are a number of 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 safely 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]


Hordenine HCl

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 Hordenine HCl 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 Anhaline, N,N-Dimethyltyramine, and Peyocatin, Hordenine HCl has undergone extensive clinical research*.  It is an alkaloid of phenylethylamine (PEA) which is also often used in high quality weight loss aids and other wellness products. This ingredient is found in nature within several different types of plants, but is most commonly extracted from the barley plant from which it receives its name, as its species is Hordenum.

There are two primary effects produced through the use of Hordenine HCl which are considered to be beneficial to dieters who want to lose weight more quickly and easily.  The first is that it provides an energy boost, which can make it much easier to maintain the drive that is required to keep up with daily exercise routines.  The second is mood support in order to assist in the maintenance of a strong motivation level.
