    Russ 9/6/2019 AMAZING PRODUCT: I started using this product last month and it has worked great! I felt the results right away! My appetite has been suppressed and my energy has improved greatly! I can't wait to buy more!

    5 out of 5

    Great Product. Great product. Banned substance free. No side effects. I take it once upon waking and another dose in the afternoon on an empty stomach. I had no issues taking it without food and did not have any jitters or negative side effects. Definitely noticed a boost in energy after taking the second dose during the day. Good stuff!

    Great product This stuff is amazing! However, it's not a miracle pill. It's not going to do the work if you don't. With diet and exercise, I feel like I burn more and I have more energy. The appetite suppressant is great, I can go about my day without feeling hungry and then eating poorly. I highly recommend it with the CLA.

    These work! I begun taking these pills this week, and decided based on other reviews to take 1/2 the normal dosage per day of 5 pills. I immediately felt the side effects of them, with a diminished appetite and increased energy! I cannot wait to complete the bottle - which includes a months worth of doses (5 per day).

    great fat burning ingredient profile!!! I chose this product because of the ingredient profile, which features several supplements that have been shown to assist weight loss and who doesn't have a few pounds that they would like to lose,especially in Florida during pool/beach season? Carnipure,caffeine,apple cidar vinegar, and yohimbe along with a few other supplements combine to form a very promising fat burner. I am currently one week in on my trial run of Unaltered's Fat Burner and all though its too early to really see the effects, I can certainly feel a difference in my energy level and overall sense of well being. It has certainly been much easier to get my workouts in as I actually feel like getting off the couch and hitting the gym and sometimes that is the hardest step in getting in shape or at least for me anyway. I will update this review in a few weeks after I have a better idea of how effective this supplement is for weight loss.

    This fat burner has helped me along with a decent ... This fat burner has helped me along with a decent diet and exercise lose almost 15lbs since I’ve started.. thank you again unaltered!

    works well Was skeptical at first , but tried this anyway and glad I did. At 65 years of age, it is a little more difficult to see results of my efforts. Slow metabolism. BUT, 10 days after using only 1 capsule per day in the morning, I was down 3 pounds. I did not have any issues with jitters, dry mouth, sleeplessness, only appetite decreased a little and I had a little more energy, nothing alarming. I like this product as it supports my fitness efforts.

    Excellent product. This product is the extra push I need to incorporate cardio into my weight routine. Gives me more energy and no slag at the end of the day. Highly recommend.

    I love it "I cannot say enough regarding this item other than IT WORKS. After only 20 days, I felt more vitality, less craving, better state of mind, and I HIT MY WEIGHT GOAL! I adore the way that it contains the genuine legitimate measurements of fixings versus other inexpensively planned items."

    Fat burner actually works Have been taking this fat burner now for right at 2 months. It actually works. Taking the correct dosage and staying consistent, as well as maintaining a hard work ethic in the gym allowed me to get closer to my results. I would recommend this supplement to anyone who may be looking to drop some weight. This isn't going to make you lose 50lbs, but if you're looking for that extra push, then I highly recommend Unaltered's fat burner.

    Increased energy and actually aided with weight loss I am not the one to normally take fat burners, but I tried out this fat burner and I am taken away! After taking the fat burner I had such an increase in energy! I've always struggled losing weight even with healthy eating and half marathon training, but after taking this fat burner, I was actually able to lose weight! This pill did not make me feel gittery with no other side effects!

    Would buy again Originally, I was a bit skeptical to buy the product because "magic weight loss pills" do not have the best reputation in the fitness industry. After hearing positive feedback about the product though, I decided to give it a try. What appealed to me most was that this pill consisted of all natural ingredients, so I was confident with what I was putting into my body. Once I got ahold of the pills, I followed the instructions to take it after every big meal and I've been doing that every day. Now that I've been taking these pills for the past two weeks, I have noticed a big difference. My metabolism seems to be working more efficiently targeting some of my tummy fat, I've lost 5 pounds in 2 weeks! Don't get me wrong though, I still work out and eat healthy on top of this pill but it seems to be aiding my progress. Im really happy with the product and the seller for being so informative by getting back to me quickly and I would buy it again.

    Amazing Product-ordered 3 times already! I have ordered this product 3 times and I absolutely love it. I am more defined and it gives me that extra boost of energy to step up my workouts.

    5 out of 5

    Best Fat Burner! I love this product. I don’t feel jumpy from the caffeine like you usually do with most fat burners. And, I’ve noticed a difference in my metabolism already! Highly recommended!

    Fat burner This stuff rocks! Just finished 1st bottle and I can all ready see results. I take 3 in the morning when I awake and 3 more in the afternoon. Definitely helps me control my appetite and gives a little extra boost throughout the day. I would definitely recommend a try.

    Great supplement to help with weight loss I really feel that this product has helped me I’ve lost a total of about 8 pounds

    5 out of 5

    Fat burner that actually works I really like this product because it is effective and the product makers really put thought into the things that go into these pills. They are easy to swallow. I have already noticed my physique getting more lean after just a few weeks of taking this product. I recommend this product to anyone who is looking for a reliable fat burner.

    5 out of 5

    Definitely worth it! I am very impressed with this product and I can say this is the best fat burner out there! I noticed results in such a short time that it made me wish I had gotten this product sooner. I definitely recommend it!

    5 out of 5

    CLEAN AND EFFECTIVE I've personally tried several different fat burners and I'm more than happy to say that my search has come to an end. The packaging alone made me love the product, but you truly feel the pills working within minutes. I take them first thing in the morning and the burst of energy gets me motivated both at the gym and for the rest of the day. Plenty of servings for the price, can't find anything to complain about!!

    5 out of 5

    what is better than natural ingredients? LOVE that all UA products use only natural ingredients. Also, my favorite part about this pill is that my cravings have surprisingly decreased and I don't need as much caffeine throughout the day to feel energized. Usually I will drink about two cups of coffee as well as pre-workout before going to the gym but lately I haven't felt the need to take pre-workout. I am excited to see how much improvement I can achieve with this product as I continue to take it :)

    5 out of 5

    Works well The ingredients in this are great, a good blend to assist in your fat loss. As always, nutrition and training are the most important part, but it can be very useful for that extra edge!

    5 out of 5

    A supplement I actually FEEL! Just got my bottle last week and I'm enjoying the effects so far. I'm feeling a great jolt of energy and feel no nausea or discomfort. From only a week of using it I can see some changes already in the appearance of my body. Leaner, more defined and still hydrated and feeling healthy. Really gonna give this the full test but so far it looks promising and would recommend it to my friends.

    5 out of 5

    No more cravings, no questionable ingredients! This product is a MUST if you want to kick your carb cravings! I can finally go in between meals without wanting to eat unhealthy snacks. Another huge bonus about this product is that the ingredients are all natural. When it comes to products that are formulated to enhance calorie burning, you never really know what you’re consuming; however, this product has the highest quality ingredients that are not synthetic or bad for you! I will absolutely be buying again!

    5 out of 5

    Great product, great results Having taken just about every fat loss product on the market I can say that this product delivers in energy and thermogenesis. The energy is smooth and consistent. No jitters. Very effective for pre cardio and mid day drop in energy, especially when diet. The results have been great in the last 6 weeks I’ve dropped from a 34 waist to a 32. The best part is this product is clinically dosed with ingredients proven to work. I can say enough about unaltered products. Great formulas at affordable prices that deliver safe, natural results. Definitely will be purchasing again.

    5 out of 5

    High-quality natural product I love the almost immediate thermogenic effect of this fat burner. Not only does it help assist with fat loss, but it also provides a nice energy boost to power me through my workouts, even when fasting.

    5 out of 5

    Works Great! I decided to try this because I've had great success with other Unaltered products. Yet again I'm happy I decided to go with the brand. No side effects or jitters. I've been taking them for a month now and it's been the first diet supplement I've ever taken in the afternoon that doesn't effect my sleeping. I feel it does well suppressing my appetite also. I highly recommend!

    5 out of 5

    Works great, no jitters I'm using this product in conjunction with an 8 week calisthenics program. Results are good so far with reduced body fat percentage and increased skeletal muscle mass after 3 weeks. My trick is remembering to take 3 pills in the morning on an empty stomach and 3 before lunch. Consistency is key. Great product.

    5 out of 5

    Great product, real results I LOVE this product. There are a lot of pills to take but it is much easier than some of those huge pills from other brands. This product is locally made which is important to me. The appetite suppressant is great and I can really feel my body heat up. With proper diet and exercise I’ve seen a noticeable difference and people ask me what my secret is. Loyal customer now and will recommend to anyone who will listen.

    DIDNT GIVE ME THE JITTERS & HELPED ME LOSE 10+ POUNDS This fat burner is potent and the best out on the market right now. Amazing results! What I love the most is that Unaltered took the time to send me a personalized note. This is a company that not only cares about their product but also their customers. I know when I’m buying unaltered that I’m getting an honest product that has top of the line ingredients and potency.

    5 out of 5

    This is my second 5 star review for this product. The product is still amazing and still works great! But I wanted to do another review to thank them for giving more capsules in my recent order! It’s usually 90 capsules, but I got a bigger bottle for 150! You guys just get better and better!!! Keep it up! :) UPDATE: 3rd review and still in love! 6 pack is coming in beautifully and this gives me awesome energy in the gym, and helps to burn fat. Get this stuff! I highly recommend it and still can’t live without it!

    5 out of 5

    Great for curbing appetite and increasing energy throughout the day! I don’t normally like to use supplements, but this one has really natural ingredients so I actually feel good using it! This works well when combined with working out and a caloric deficit (like any other fat burner) so it is a great supplement for anyone who is trying to lose fat. I didn’t take any progress pictures because I am doing an extremely slow cut and taking my time with it, but this has been super helpful in controlling my appetite and giving me energy! I am usually HUNGRY AS HECK 24/7 but this helped me manage my appetite and to actually stick to my caloric deficit. Also, taking this in the mornings really helped give me energy in the mornings! I am a full time grad student and usually have to drink coffee every single day, but with this, I don’t even need to drink coffee. And I don’t feel jittery or “crash” later. It feels like sustained energy throughout the day. Overall, I think this is a great supplement and helps you stick to your caloric deficit and workout program. Just make sure that you stay disciplined and do what it is that you need to do to actually lose weight and remember that this is just to help you get there. :-) good ingredients, will be purchasing more!

    DONT LOOK ANY FURTHER…BEST FAT BURNER OUT THERE! I cant say enough about this product other than IT WORKS. After just 20 days of taking the UNALTERED Fat Burner, I felt more energy, less hunger, better mood, and I HIT MY WEIGHT GOAL! I love the fact that it contains the actual proper dosages of ingredients versus other cheaply formulated products. Personally, I use the UNALTERED Whey Protein Isolate every day along with the UNALTERED Fat Burner because the protein contains less than 2g of carbs/fat and it has 30g of protein, so it definitely helps me to take in less calories while still maintaining lean muscle and burning fat. Awesome fat burner and cant wait to get more.

    No Jitters at all, great product... I have been on my fitness journey for almost a year now, so I have recently decided to add a fat burner to my routine to help with the little stubborn spots I have left. I like to do my research and when I found this company on Instagram, I decided to give them a try. I’m so glad that I did. I have tried other fat burners that have had negative side effects for me. With this brand it has been smooth sailing, no jitters at all. I don’t like that feeling of shaking or feeling completely hyped up. I have been taking them before my workouts and I feel like I definitely sweat more and have energy, but not that fake feeling. I don’t really know how to explain other than to say it feels natural with my body. I have been taking these for roughly 2 weeks and will absolutely continue to use them. If you’re in the market for a fat burner, these are a great way to go!

    Noticed Increase in Energy and Decrease in Appetite! Without feeling nauseous!!! I am a 40 year old pro figure competitor who competes in a natural bodybuilding federation and I have tried several different fat burners over the years. When I came across the Unaltered Athletics line and saw that they take special consideration in keeping their products made with ingredients safe for natural athletes I knew I wanted to try it. I am someone that takes great care when selecting any supplements to be sure there aren't any banned substances in them. Unaltered took the guess work and research out of that for me. The packaging even states right on it "No Banned Substances". Love that! Prior to trying this fat burner I had given up on that type of supplement as all of the other ones I took either made my stomach really upset and made me nauseous, or they just didn't do anything at all. I am so glad I gave this one a shot! I immediately noticed an increase in energy and also noticed my appetite decreased, which helped ease the anxiety/agitation/bad cravings I sometimes feel when I am cutting hard to lean out. I have not noticed any negative side effects from this product and I highly recommend it for anyone looking to lose weight (regardless of your fitness level or goals). When paired with the right diet I believe it definitely can help! But remember, this is a supplement used to help with whatever program you are following. As everyone knows, there is not a magic diet pill out there that works alone - you still need to do some work for any results to happen. Definitely worth the money and will order again!

    Definitely my favorite fat burner, so far! I don't usually like taking fat burners. It's so hard to find a clean fat burner that isn't chocked up with all kinds of chemicals and stimulants that only leave you feeling jittery and weird in the end. I didn't want a "diet pill." I wanted something that would make my workouts and food consumption more effective for burning excess body fat. On top of that, I wanted something made from clean, natural ingredients. Not an easy find in today's supplement market. So, when I found Unaltered, I was pretty excited. I have been taking their fat burner and CLA for a few weeks, with amazing results. First off... It's definitely thermogenic. I can tell this by how much I sweat while working out, which for me is a good thing, because I don't sweat enough. When cutting carbs and my energy sources from my foods, this fat burner definitely provides some supplemental energy to knock out my workouts. My body fat percentage dropped within a couple of weeks and I am leaning out quite nicely. I definitely recommend trying this brand if you're looking for an effective, clean product.

    Great Product! I highly recommend this product to anyone that is looking for a natural supplement to aid in their fat loss. I enjoyed this product because it does not make me feel jittery like many other fat burning supplements on the market. My main goal right now is to increase calories without gaining excess fat. This product allowed me to increase my calories without adding any additional cardio or extra training to my normal regimen! Additionally, I noticed an overall improvement in body composition after about 3 weeks of use, which suggests that it is TRULY TARGETING THE FAT rather than muscle such as some weight loss pills.

    5 out of 5

    10/10 I usually don’t take any supplements because they make my stomach hurt. However, this fat burner is a quality product and I can tell because not only did I see results quickly. But also I never made my stomach hurt and it didn’t give me the jitters. 100% recommend this product for anyone looking to shed some fat and tone up. Best results when used with Unaltered CLA!

    5 out of 5

    Shredded with no jitters This fatburner has all quality studied ingredients with strong dosages and produces no crash or unwanted side effects that other burners can provide. With one bottle I've cut off several inches off my waist and I'm seeing more definition around my limbs and face. Very happy with this product.

    5 out of 5

    Outstanding fat burner! I will say that this is one of the best put together fat burning products I have ever used! The ingredients are well thought out and work together wonderful! I never recieved any joggers or crash while running this one unlike some others I have used in the past! I used this fat burner along side their test booster during my last competition prep and received outstanding results! I am running it again for my upcoming show in September!

    5 out of 5

    This Fat Burner works I absolutely love this product. It is the first fat burning product that did not give me any negative side effects. The ingredients are the best natural ingredients. UA has food the perfect recipe. Since taking the Fat Burner I have noticed I have more energy through out the day. I no longer have the dreaded afternoon crash. I have noticed a substantial decrease in appetite and no longer crave the foods I use to. This fat burner is definitely helping me on my weight loss journey. I cant say enough good things about this product.

    Hidden Benefits


    CLA’s unique effect on the molecular signaling receptor family known as PPAR also helps to reduce inflammation and promote a healthy metabolism which is needed to safely and effectively burn fat.
    In addition, CLA also helps to promote a strong immune system which can often be neglected when following a weight loss program.

    At Unaltered, we’re all about creating results, which is why we use an all natural blend of herbs that work synergistically to boost metabolism, while staying away from your precious muscle tissue.

    Why do I need the UNALTERED Fat Burner to lose weight?

    You don’t…but it surely would help.

    Most weight loss regimens fail because:
    1.) Lack of results demotivates continuing any weight loss plan.
    2.) It is difficult to sustain for a long period of time.

    The UNALTERED Fat Burner is not a “magical” weight loss pill that will instantly burn off all unwanted body fat (although it has been noted as possessing “magical” weight loss powers from our customers).

    However, this product will definitely help speed up the amount of time it takes to see results and will work to make your daily weight loss regimen much easier and more sustainable.

    Using only ingredients that have been clinically proven to burn fat, the UNALTERED Fat Burner will help kick-start your metabolism so that your body becomes a natural fat-burning machine, WITHOUT attacking your muscle tissue (the muscle that is needed to burn more calories).

    If you are looking to finally use a weight loss supplement that works and is backed by science, then give 100% UNALTERED Fat Burner a try, and let the results speak for themselves.

    Suggested Use: Take 2 capsules in the morning on an empty stomach upon waking in order to assess tolerance. If well tolerated, take 3 capsules in the morning on an empty stomach upon waking, and 2 additional capsules in the afternoon before lunch for a total of 5 capsules daily. If stomach agitation occurs, take with food.
