Within every American-made FENFAST 375 tablet, the following ingredients have been carefully balanced and combined:

  • L-Phenylalanine
  • Caffeine
  • L-Theanine
  • Theobromine

The first ingredient is L-Phenylalanine. This is a form of amino acid that can be found in a number of different types of over the counter products, including FENFAST® 375 and other weight management supplements. The reason is that it can provide a number of different helpful benefits for weight management and certain other health challenges. When taken in appropriate amounts, research has found that those who are overweight can manage weight more easily than they would be able to on their own.

Next on the list of ingredients in this formulation is caffeine. This is a researched synthetic stimulant that is known to promote energy and focus.
The next ingredient in FENFAST 375 is L-Theanine, which is a focus enhancer. And Theobromine is the final active ingredient in the FENFAST 375 list. It heightens the energy levels in the body while it provides extra support so that the dieter can remain active.

FENFAST® 375 Tablets Weight Management Support

FENFAST 375 tablets represent the very latest in weight management supplements. Furthermore, this weight management formula doesn’t lead to chemical dependency.

The FENFAST 375 formula was created specifically to provide the benefits that dieters need the most to be able to stick to their weight management programs. The benefits of FENFAST 375 start with an energy boost. This way, it is not only easier for you to remain active every day, because you won’t find that fatigue is a problem at exercise time, but you may also burn off more calories and fats with each exercise because your energy will be working at a higher rate.

The benefits don’t stop there. This formula goes on to provide extra mental focus through its scientifically studied ingredients. Improved focus will help you eat right, and you’ll choose the right foods so you won’t have to feel deprived. You’ll be able to more easily reduce the number of calories that you eat every day. Therefore, you won’t need to burn off as much from your food in order to begin seeing results.

Finally, FENFAST® 375 takes a step above and beyond what many other weight management pills have to offer in terms of benefits. Anyone who has tried and failed at dieting can tell you how important motivation is to being able to manage weight successfully. This over the counter weight management aid can help you keep up your drive to reach your goal right up until the moment you’ve stepped on the scale and have seen it before your eyes.

Great product!! Works as described. The price is right for what you get. I will recommend this to my friends who are trying to lose weight.

They take away your appetite but be aware that when you stop taking them you will want food again just like you always did. It's a quick fix but not a permanent plan.


I love my fensfast! I still have one cheat day a week (usually Sunday) where I don't take the pills and eat whatever I want i.e. a cheeseburger or a slice of pizza and some sweets or chips but the rest of the week it's salads, brown rice, fish and steamed veggies. Over the course of 6 weeks I have lost 28 lbs and I am extremely happy with the way I look and my new lifestyle.

These work great for me and I don't do much else, just take them 2 x a day and bye bye munchies! 😉

These will help fast track your weight loss along with proper diet and exercise but don't rely on just the pills alone or you will never learn to change your lifestyle and you will gain everything back I promise you. Once you come off the pills you will be as hungry as ever. That is what happened to me. Now I am back trying again and I vow to stick to it and keep it off this time for good.

I too took phentermine before but found that unless I took the first pill very early in the morning I would be up all night. There were other issues too i.e. really bad headaches, blurred vision, and sometimes upset stomach. I am trying Fenfast and so far I am still losing weight and don't feel any side effects. So for the moment it has my vote.

I have been taking Fenfast for a month and have lost 15 lbs. I stay away from fast food and processed foods. The odd time I will slip up but then I get right back on the program. I find it makes you feel fuller faster and you don't get the bad hunger pangs that make you want to over eat at your next meal.

I am a previous user of Phentermine but found that after the first few weeks it would wear off also I had lots of side effects i.e. insomnia, heart palpitations & constipation. I am a couple weeks in on FenFast and I feel a lot more calm and normal. I am not stressing about counting each calorie (I am really not eating much) and so far it seems to be keeping it's strength up. If it does wear off, I will take a break for a week or two then try again.

45 lbs gone

My start weight was almost 190 and after taking FenFast for 4 months I am down to a very happy 145. I am 5'3" and finally feeling amazing.

Portion Control

I can't believe how much free time I have now that I am not always thinking about food. This has turned off the cravings and given me portion control. It also gives me a lot of energy to get out and jog every day. I would recommend this to anyone who struggles with over eating.
