FENFAST 375 Customer Reviews

fenfast reviews MOMO-T-TO (Cleveland, OH)
I’ve currently been taking Fenfast for two weeks and so far so good. I’ve been burning scores of calories and I’ve dropped 11 pounds and counting.
fenfast reviews Ella Tierny (Faibanks, AK)
After hearing my best friend rave about Fenfast, I wanted to try it. She told me she’d lost 20 pounds in one month and I want that too. At first I thought there was NO WAY, but then I saw her and I noticed a difference in the way she looked. I’m going to try and beat her record and lose 25 pounds in one month. Wish me luck!
fenfast reviews Daniella P. (Little Rock, AK)
I do not believe in weight loss miracles, but I gotta say, FenFast 375is as close to a miracle as they come when it comes to losing weight fast. I’ve only been using this pill for just under two weeks and I’ve lost almost 10 pounds.
fenfast reviews Maria (San Francisco, CA)
Before I used to dread stepping up on the scale but now I can’t wait to weigh myself every morning. The next time I make my purchase I’m not just gonna buy one bottle, I’m gonna get the three!
fenfast reviews kelli (Salem, OR)
What a fantastic product, I’m so excited!
fenfast reviews Terry S. (Carlsbad, NM)
I haven’t been taking FenFast for very long, but I’ve started to notice that my appetite is less. I used to have a lot of food craving, especially in the afternoon, but I find myself looking for a snack and thinking about food less and less. This is a huge relief to me, because food has always been one of my biggest problems when it comes to losing weight. I’m interested to see if this will keep up.
fenfast reviews Patrice (Toronto, Canada)
I’ll certainly be making more orders of this product. I had no idea how good it would feel to lose weight.

The Differences Between Phentermine and FENFAST® 375

Phentermine is a prescription drug.  This means that it can be obtained only when prescribed by a licensed doctor.  It is only prescribed to obesity patients and, even then, it’s prescribed only when deemed safe and appropriate.  It also means that there may be side effects – ranging from mild to very severe – associated with its use.  Furthermore, it should be noted that Phentermine can be used for only a few weeks at a time.  During those weeks, the body gradually builds both a tolerance and a dependency.  This means that while the effects of the drug decrease, the risk of becoming addicted – and then experiencing unpleasant withdrawal symptoms – climbs.

FenFast 375 Is The Top-Selling Phentermine 37.5 Substitute


If you’re looking for weight management advantages but can’t use Phentermine because it’s not right for you, reduce the challenges of your dieting and exercise with FenFast 375 as your best option.

It is in exactly this area that FENFAST 375 truly shines. To be clear, it is in no way the same as Phentermine.  If you’re overweight (BMI of 25-29.9), and need help overcoming the challenges associated with keeping up a healthy weight loss diet, this non-prescription formula is for you.  Even better, this tablet is not associated with any powerful side effects that obesity patients need to contend with when using prescriptions. At no point will dieters be at risk of becoming chemically dependent on this diet pill.

FENFAST 375 as a Phentermine 37.5 Substitute

Although Phentermine 37.5mg is one of the leading prescription diet drugs currently on the market, and it has already helped millions of obese patients to overcome their weight struggle and reduce their body fat to healthier levels, this drug is not appropriate for all dieters.  Just wanting to lose weight isn’t enough. Therefore, there are a growing number of people who are seeking an alternative that will provide them with weight management support in a format that is appropriate for an overweight dieter making diet and exercise changes to their lifestyle.  In these cases, FENFAST 375 is providing the solution many have been waiting to discover.

As you can see, these two pills are nothing alike in terms of who they’re for and what they’re meant to do.  Phentermine 37.5 mg is meant to assist obese dieters to be able to lose weight more successfully by complementing a healthy program that has been designed with the assistance of a doctor.  This drug is not used on its own to shed excess fat, but makes it possible to diet in a traditional way, but without the challenges that can create a barrier to success.

For example, although it is necessary to reduce the number of calories that are consumed every day, the appetite suppression helps to stop dieters from struggling with this effort by reducing the battle with hunger.  Smaller meals are more satisfying, and the need to snack is reduced.  Similarly, dieters are also required to keep up with a daily workout.  Though fatigue is a constant struggle for individuals on a calorie reduced diet, Phentermine 37.5mg provides an energy boost that helps to overcome that obstacle.

FenFast 375 vs PhentermineOn the other hand, FENFAST 375 proprietary formula offers this outstanding support to overweight dieters keeping up a healthy diet and regular exercise:

  • Energy boosting
  • Healthy metabolic support
  • Focus and alertness increasing 
  • Support needed to successfully keep up with healthy weight management

Clearly, the differences between FENFAST® 375 and Phentermine include pretty much everything aside from the fact that they are both sold in pill form. Still, it is precisely these differences that have helped the non-prescription tablet to become an ideal alternative for so many dieters. After all, just because you’re not obese, it doesn’t mean that losing weight is easy.  Added help in successfully maintaining a weight management strategy is always welcome.

Phentermine 37.5mg (also known as Adipex) is a prescription drug.  It can only be prescribed by a licensed doctor, and only under certain specific circumstances when the patient is adequately obese and is at risk of serious health conditions due to that fact.  It is a short term solution as the body builds a tolerance over time so it becomes less effective.  Using this drug too long places the dieter at risk of addiction and withdrawal symptoms.  Moreover, at any point during the use of this medication – especially at the beginning – the dieter may experience mild to very severe side effects.

FENFAST 375 is a non-prescription diet pill.  It can be purchased without consulting a doctor and can be used throughout the length of a dieter’s efforts to lose weight.  The benefits are helpful, lasting and not associated with severe side effects or chemical dependency.  When you can’t use Phentermine 37.5 because obesity treatment isn’t right for you, that doesn’t mean help isn’t available. Instead, it’s right here at your fingertips.

I didn’t have high hopes for using fenfast but it definitely proved me wrong. I haven’t had luck with pills in the past, so I thought that this might just lightly take the edge off of hunger, but it did a lot more than that. I’ve lost 14 pounds in three weeks and am still losing. It doesn’ tmake dieting easy, but it does make it a lot easier than it has ever been.


Marq August 21, 2011 at 6:29 pm

As soon as I got using Fenfast, I didn’t have to worry bout overeating no more. It’s just a matter of control that I got now.


LIz Rosenblat September 24, 2011 at 8:51 am

I lost all of the stubborn baby weight that I have been struggling to try to get rid of for 8 months. It just never seemed to come off until I finally started using Fenfast. That made all the difference for giving me the energy I needed and to eat without snacking.


janet February 8, 2012 at 7:17 pm

After having been on two different diets where I used prescription Phentermine to lose weight (and then have it come back on again), I’m completely sold on FenFast! I am losing the same amount of weight except that I don’t have the side effects. After 2 weeks, I’ve lost 7 pounds already! That’s just how much I was losing with the prescription, except this doesn’t need me to go see my doctor for it.


bex February 12, 2012 at 3:41 pm

As far as my hunger goes I have to force myself to eat. I love my fenfast.


Maureen April 22, 2012 at 5:23 pm

Fenfast just blasts the weight off. 2 walks a day and eating lighter from no appetite has gotten me 15 pounds gone in just over 3 weeks. I’m back to buy more!


Alicia March 30, 2013 at 9:46 am

That’s great! I’ve been doing two walks a day and I have been eating better than before, but I know I have room for improvement because in 3 weeks I’ve lost 11 pounds. How long are your walks? Maybe that’s the difference. Do you walk as fast as you can?


Shannon June 28, 2012 at 12:59 pm

I’m hoping to lose all of my extra weight in one month. I’m exercising every single day and not eating more than 1200 calories. With fenfast, I’m not hungry and I have lots of energy. It’s all going to be gone, I know it.


Asher July 16, 2012 at 4:21 pm

I have been taking phenblue for five weeks now. That means that I’ve just started my second bottle not long ago. It has really meant a massive difference in the speed of my weight loss. I’ve lost 22 pounds so far and I know that this will continue because my appetite has stayed super small.


Journey October 1, 2012 at 5:01 am

I won’t ever diet again without the help of Fenfast. It makes so much of a difference that I lose in one month what I would usually lose in four! So what I would usually lose in a year, I could lose in three months with these diet pills.


Sean December 16, 2012 at 11:04 am

Since I stopped playing football in high school I can’t seem to burn off what I’m eating anymore. I don’t want to stop eating the stuff I really like so I needed something to make my gym workouts go further. Fenfast is just enough to top me up so I can keep eating like I want but I can work it off again.


Gloria January 9, 2013 at 4:34 pm

My husband and I are both taking Fen Fast and I am down 17 lbs in the first month and he is down 18lbs! I think it’s one of the best diet pills out there the only thing is the contant dry mouth it makes you drink a lot of water. I don’t leave the house without a water bottle.


Chloe March 24, 2013 at 11:16 am

I’m taking Fenfast with my husband, too, and every week he loses more than me. It’s driving me crazy because I’m working way harder than him. Do men lose weight more easily than women? Do they burn more calories from exercising or something? I’m going bananas. I really want to beat him at least one time (I’m a bit competitive haha).


Vanessa April 6, 2013 at 7:56 pm

Eat healthy foods that are high in fiber and focus on exercises that really kick start the fat burning in your Fenfast. This is mostly cardio, so anything that really gets your heart pumping and makes you breathe faster. Get active every single day! You show him, Chloe!


jenn May 8, 2013 at 7:42 pm

Yes men lose weight easier than us. They have more muscle mass which means they metabolize more efficiently. We are made to have babies so the fat clings on for dear life. The more we try to get rid of it the more it wants to stay! It’s like our bodies think any minute their might be a famine or something and we will need the reserves lol


Jennie February 23, 2013 at 2:30 pm

I’m just starting my second month with FenFast 375 diet pills. I have never lost this much weight so fast in my life. I’m already down by 16 pounds! I’ve been exercising hard and eating right but these pills really work to make it easier by a long shot for me.


Ronald D March 1, 2013 at 5:09 pm

This isn’t your average diet pill. I try to stick to all naturals but I’ve tried chromium, green tea, and hoodia and they really don’t help very much. FenFast totally kicked their butts. It supercharges me for my workouts and it stops me from getting the munchies afterward so that I can actually burn the calories without replacing them.


Sammy May 12, 2013 at 9:22 am

None of those other pills work. I’m starting to think that the only nonprescription that does actulaly work is Fenfast. I didn’t like the way that I felt on phentermine, so I tried pretty much everything out there that is natural. I like the ingredients in this formula. I get great energy and I’m barely ever hungry. It’s a very complete package.


Jessica March 13, 2013 at 7:06 pm

I just started taking Fenfast 3 days ago and I’ve lost 2 pounds!


Alondra March 17, 2013 at 11:53 am

When you compare Phentermine with fenfast you’d practically think that they are the same, exept that when I take the over the counter one, I don’t end up with the feeling like my heart is racing and that I’m so anxious. As long as my appetite is smaller, I gets more energy and I lose the fat, I don’t care if it’s prescription or not.


Gary F May 25, 2013 at 6:35 pm

That’s what I got out of using fenfast, too. I didn’t really have the same experience with Phentermine, though. I struggled a lot with my prescription which is why I started using an over the counter. I do get the same weight loss from them, which is why I agree with you, but my prescription had more side effects with it than I can count.


Eric March 23, 2013 at 3:41 pm

Do I have to take 2 fenfast pills every day to get results or can I try it with just one? If I want more, can I take 3?


editor March 25, 2013 at 12:42 pm

@ Eric – You can take just one tablet a day if you wish, but the manufacturer warns against taking more than 2 per day.


Maile March 29, 2013 at 10:14 pm

Yes you can take only one. Lots of people have success with taking only one.


Jada March 28, 2013 at 9:58 am

Can you take fenfast only with water or can you take it with other drinks too? I’m only asking because it’s hard swallowing pills and I find it easier with milk.


Ann Q. April 4, 2013 at 10:25 am

Jada, I say take it with whatever beverage makes the pills go down. I personally find it easier with milk too and, so far I’ve not run into any trouble. That said, because it is recommended you take it with water on an empty stomach, I just swallow only as much milk as I need to make the pill go down and then I follow that up with a full glass of water. That way I’ve got more water in my system than milk. Don’t know if that will help you but since taking the pills is rather important for the product to work, you need to get them down somehow, right?


bex April 6, 2013 at 6:40 pm

You can take it with other dinks I would avoid anything with caffeine though.


Maile April 12, 2013 at 10:18 am

See I love taking it with my coffee I can really feel it kick in and then it’s like wow! Now I know feel all that extra energy everyone is taking about!


Maile April 7, 2013 at 6:12 pm

I don’t see why you can’t take it with milk, it is just probably more effective with water though.


Caitlin E April 14, 2013 at 10:48 am

I am going to start by using just one of these Fenfast pills every day and see if I can get results just with that. That way, if I need more help I know I can take the second one.


ODC April 15, 2013 at 10:51 pm

I am wondering what the side effects are. I don’t want to feel like i am going to have a heart attack. Thanks


jenn May 8, 2013 at 7:42 pm

just a dry mouth, nothing too crazy. drink a lot of water and you will be fine.


Holly Donald April 18, 2013 at 1:37 pm

Thank you Fenfast! I just got on the scale ten minutes ago and I’ve officially lost 25 pounds. It’s the easiest diet I’ve ever done. I still had to focus on doing stuff right but at least it wasn’t filled with feeling hungry every hour or being so exhausted and depressed that I don’t want to get out of bed. Nope. It has all been positive for me. THANK YOU!


Bert April 27, 2013 at 12:16 pm

I have now taken Fenfast 375 tablets for a complete two months and I can say that these are effective pills. I recommend them to someone who can’t get weight to go away in other ways because of struggles with hunger or because it is just too slow. Sincerely, Bert Winchester


Greg H. June 23, 2013 at 1:16 pm

I’m losing weight at a pretty good speed with FenFast, but is there a way to make the weight loss faster? Can I take four pills a day instead of two?


Ally July 6, 2013 at 9:47 am

I have to say, I’m not super impressed with these pills. It’s been two weeks and I’ve only lost 5 pounds. I was really expecting to lose more. I take half hour walks every day and I’ve cut out the night time snacking. Am I doing something wrong?


Fat man gone slim fast July 17, 2013 at 9:12 pm

At first I didn’t quite understand the name of this diet pill product, but then I started using Fen Fast and it started making a whole lot more sense. I started losing weight fast. In the first week I lost 4 pounds. That may not sound like a lot to anyone who is reading this, but if you’ve ever tried dieting, you’d know that losing 4 pounds in one week without doing any crazy dieting is fantastic. I’m on my third week and am still losing. My weight is currently down by 12 pounds.


Sheena August 4, 2013 at 7:19 pm

FenFast is really great. It’s not as powerful as Phentermine in my opinion, but that’s just fine with me. It still suppresses the appetite and I don’t have any bad side effects like I did on Phentermine. That drug is seriously killer!


Gina G. August 18, 2013 at 9:56 am

I love this pill, I really do, but I really wish I didn’t have to work out so much to lose weight. I know that’s all part of the process, but it would be nice not to have to exercise all the time. Ah well, guess I can’t complain at losing 15 pounds in one month.


Simon F. September 1, 2013 at 1:34 pm

Fenfast sure does work fast. The name of this pill makes total sense to how it works. My entire diet has changed since I’ve been on it and I feel a lot better and not so bogged down by food after I eat. I have more energy and am much more inspired to move around. It’s done good things for my weight and my mood!


davidson May 13, 2016 at 10:43 am

The formula for FenFast includes ingredients that help to boost both energy level and mood. These are often overlooked advantage that can make an important difference toward a person’s chances of successfully achieving weight loss.


Jennifer G February 21, 2019 at 6:51 pm

I just got my fenfast today and intend on starting tomorrow I have taken phentermine10 years back and done good but ive gained a lot of weight since then(about 25lbs) and have gotten older I was wondering if I should take 1 or 2 being ive done the phentermine before? ive read everyones comments and hoping this works well for me the past month ive been doing 1 hr walks daily and cutting back my calories and only lost 4lbs and none of my clothes feel like ive lost 4lbs …hoping so bad this works as good for me as it has others!
