You can burn a lot of fat by working out. But your body has its own fat burner too. It’s called thermogenesis. Cellucor D4 Extreme taps into the benefits of thermogenesis using ingredients that are proven to stimulate this process.

Cellucor D4 Extreme Ingredients

The ingredients that promote thermogenesis are stimulations. Cellucor D4 Extreme has several of them including Caffeine, Evodiamine, and Sclareolide.

Thermogenesis is the process in your body that control body temperature. When you ingest certain stimulants, your body temperature will increase and so does the rate of fat burn. Caffeine is especially good for stimulating this fat burning result.

The ingredients in Cellucor D4 Extreme all come in a proprietary blend so we can’t see individual ingredient amounts. However, the label does specify that each serving of this fat burner has 150 mg of caffeine, which is a good dose.

In addition to stimulants, Cellucor D4 Extreme has White Willow Bark Extract which amplifies the effects of caffeine. The fat burner also has Octopamine HCI which may improve the breakdown of fat cells. Another noteworthy ingredient is Yohimbe Bark Extract. It acts as a vasodilator and increases blood flow to the muscles.

As previously mentioned, the active ingredients are combined into a proprietary blend. There are eight ingredients in the blend and it totals 588 mg per serving.

Will Cellucor D4 Extreme Work?

If you want a fat burner that promotes thermogenesis, Cellucor D4 Extreme does this pretty well. It has some great ingredients and some great stimulants. However, we do have a few concerns with the formula.

First, the doses seem to be on the small side. We know that there are 150 mg of caffeine, which is good. But that leaves 438 mg for the other seven ingredients. These small doses could prevent Cellucor D4 Extreme from producing all the results that it is supposed to.

Second, since it has so many stimulants, there is a good chance that Cellucor D4 Extreme will cause side effects. Common ones are jitteriness, nausea, headaches, and dizziness. Usually, stimulant-related side effects only affect people who are sensitive. But with so many stimulants, Cellucor D4 Extreme could negatively affect more users.

Cellucor D4 Extreme Price and Guarantee

The average cost for a 120 capsule bottle of Cellucor D4 Extreme is $62.99. The official website does offer a 100% money back guarantee. This allows you to try the product risk free. If you don’t like it you can get a refund.


Cellucor D4 Extreme is not a fat burner for the faint of heart. The large number of stimulants could burn fat, but they could also cause your heart to race and your head to spin.

If you are still interested in trying Cellucor D4 Extreme, we won’t discourage that. However, we know that there are better fat burners than Cellucor D4 Extreme. So instead of spending any time or money on this product, we suggest that you try one of the best fat burners.

Getting my body Back | August 10, 2013

Let me start by saying I’m not a person that intakes caffeine regularly (No coffees, teas, or sodas) And D4 has a lot of caffeine in it. Im also 315lb female about 5’2″ tall. (Gained nearly 70lbs after a sports injury) Im trying to get my body back. I usaually workout 5X a week with low carb low fat diet but my weight lost results have been subpar for my effort. So i decided to try a supplement recommended my the assoicate at GNC. This is my experience with D4.

On my 1st day I took one pill at 7am in the morning. I felt like I was high (never a drugy either) shorty after, about 20mins I could not stay still. I felt the erge to be evolved in physical activities all day. I did not want to stop working-out! It did wear off around 1pm in the afternoon, no crash it was gradual. Did the same on day 2 and got the same results. On day 3 I decide to take 1pill in the morning and another in the afternoon. As a result I was overly active, in a good way. Working out, cleaning house, yard work, ect. D4 gets you really motivated to do those chores at the bottom of your list you prefer to skip. On day 4 I took 1 pill morning & 1 in the afternoon. Once again the effects were equal. On day 5 I decided to take the 1 pill in the morning only and avoid physical activity, as an experiment. As a result I had serious jitters, a headache and was mentally frustrated because my body had the desires to get active and I would not give in. The feeling was like having workout withdrawals. I was litterally shaking in my seat as i tried to reamain seated and watch tv. Day 6 I did not take it at all and my daily activities went back to normal typical workout and down time. Day 7 I went back to 1pill in the morning & 1 in the afternoon. After 1 week I lost an amazing 12lbs ( I wonder if this is what they use on the Biggest Loser contestants).

My advice if you are an active person or a person who wants to heighten your daily activity level D4 works great. If you’re lazy I wouldn’t recommend as the side effects only surfaced when I was a couch potato. If you do decide to take D4 give yourself at least 1-2hrs of high level activity followed by moderate activity such as cleaning or something after each dose to help your body get through the stimulation otherwise you probably won’t like taking D4.

Yes, I recommend this product

Energy Booster

This product was recommended to me by the salesman at GNC. I am on day three. I take one a day first thing in the morning on an empty stomach. Then, I workout and then I eat breakfast. I’ve experienced more sweating or flushing and some mild headaches. It has increased my appetite a bit, so I have tiny meals(or snacks) during the day, but I don’t eat past 8pm. I have only been working out once a day, but will probably up it to twice a day by next week. Stay tuned…

I have been taking D4 for 2 days ….This pill works great!! It does not make me feel jittery, hungry or sick. It gives me so much energy. I am more alert and focus….I have lost 5 pounds in 2 days. I take 1 pill in the morning and 1 in the afternoon.. I also had a bit of flush and heavy sweating around my problem areas…(abdomen, buttucks and thighs). I would recommend this product.

I have been using this product for 3 days now. This pill works great! After just the first day I had lost 3 pounds. Now after 3 days I have lost 5 pounds. You have to drink lots of water to get the best results. Also, eat before taking this pill. If I don’t eat I get a huge stomach ache. Other than that I have not had any negative side effects. I have not been jittery at all. I am more alert and have a ton more energy. I would recommend this product.

just started it. Has been giving great workout energy. Added a fast 1.5 miles to my run on the tredmill and pushed more weight. People should understand it’s not a magic pill (they dont exist). If they make you feel sick, then obviously your body is sensitive to this kind of stimulant. Try not taking them on a totally empty stomach, and drink LOTS of water.

D4 Pills

Well I have been using D4 for about 3 weeks now and I can honestly say I don’t see much results. It could be because I don’t eat as healthy as I should but I have cut out most of the bad foods I use to eat. I also go to the gym at least 5 times a week for about an hour. I did cardio for 45 minutes for the first two weeks and I’m now beginning weights and cardio. Some side effects I get is a massive headache and irritable. UGH i hate the headaches. But I’m going to finish the bottle & if nothing drastic happens, I am going to be pissed because I was convinced by GNC that this was the best out here “/

i just had to stop in the middle of my workout to come online and write about this stuff. If you want to push your limits, break through a plateau, and push yourself to get an insane beyond insane workout you need to try this product. I just lifted up my laptop to write this and it felt no heavier than a feather. Im just beginning training again but i’ve been using other pre workout products over the last 2 years and nothing compares to this. Try orange it tastes like a creamsicle.

I was at GNC looking for a new fat burner for my workout and the guy working there swore bye D4 by Cellucor. Long story short….I have been working out 4-5 times a week with at least 20 min cardio following 40-45 minute resistance training…and I can honestly say that besides heating me up a little, this supplement is not working for me. I have used products like Hot Rox and Xenadrine in the past and both have cut at least 10lbs off of me in a month. D4 just doesn’t cut it and is over priced!
