D4 has been my favorite thermogenic. It gives me plenty of energy and curbs my appetite. This is a great product.

I purchased this product 2 weeks ago and have been taking 2 tablets twice a day. I found that taking it on an empty stomach wasn't a good idea. It says it curbs appetite, but I eat then get hungry around the same time I usually do. I am a college student and I will say I'm glad it doesn't give me jitters in the morning while I'm sitting in class, and I do feel slightly more focused. Definitely makes me sweat, even doing the smallest of activity. I can't say I've seen a dramatic change in body weight or appearance. I lift 5 times a week intensely and 30-45 min of cardio so I thought I would see some sort of change but, I plan to continue and finish the bottle and make a final opinion then.

I would say it is a decent energy product.. I will give it a 5 on the fat burner partially because i dont have much fat to burn ....But energy wise it is decent

Bought this product after I found out metabolic Nutrition discontinued Synedrex old formula so I bought this at my local vitamin store and 10 minutes after taking it I got really bad headache, mood swings and a really hungry, however I do felt my body temperature was higher than usual but the headaches would not let me workout. I also started working out early in the mornings with empty stomach and noticed a massive change, unfortunately due to my work schedule working out in the morning is not convenient for me so taking this product before hitting the gym in the afternoon is a big no no.

I tried this product for a month. I gained 7 pounds!! When you stop taking it there is a major crash! First day off of it I had to take 4 naps during the day. Total scam.....don't fall for it.

Another great cellucor product. Tons of energy throughout the day. Appetite felt under control. Didn't feel hungry, just ate when I needed too. Dropped 10 Lbs after a months cycle. Helps keep a calorie deficit and keeps energy high. I would recommend either D4 or Super HD to anyone trying to get that extra push to lose those unwanted lbs of fat.

I've used this to cut weight several times. Make sure to give it a good 30 minutes or so.

I bought D4 Thermal Shock today. I took it on an almost empty stomach (mistake) at 5pm. I started feeling queezy at 8pm. I will continue taking it after eating breakfast. My body got hot but not sweaty. My cheeks next to my nose got really red n swollen, my pores looked big. My chin n between my eyebrows were red also. I did not feel energy, but felt it was working, cuz it made me go flush out my system. Im 5'1" n wiegh between 165 n 175 not sure. I dont like scales, they're depressing. I like to measure myself to see my results. I will continue using n will update my progress in a week or 2. Also im stacking this with Relacore Extra. At 9pm I started feeling very sleepy. Only 4 hours after taking it. But I have high hopes for this product after reading alot of the reviews

This product is fantastic. I was really concerned about putting fat after all my elite level competitions this year, I initially tried the Cellucor Super HD and and loved how fast my body responded to that. When I finished that I started on Cellucor D4, I also found this helpful and I am pleased that my GLUTES are still firm two months after representing team Canada at the IFBB World Championship.

Ok so I bought this product well initiated to pre workout stimulants. I took one and waited for it kick in. Starting to feel disappointed I thought eh I will take another to see if it will give me at least a little jolt or make me feel like my core is warming. Here was my first mistake... The first one started to kick in and then the second. You ever see that seen in Beavis and ******** where Beavis morphed into cornholio... That's exactly what happen I started to heat up and have sweat forming on my lower back. Also my heart rate was quite elevated. I got to the gym and blew through my typical workout of 1.5 hrs in a matter of 45 minutes. I drank about a gallon of water in that time and continued to drink water when I got home. I can definitely testify to the strength of this product. Do yourself a favor and take one and give it about twenty five minutes. I would compare it to the original hydroxycut . If you're looking for something to amp up your calorie burning give it a whirl.

I noticed no difference with C4 except for the itching it causes almost right after taking it. I won't be buying this again as is did nothing for me.

I have migraines, most fat burners I've tried trigger headaches. I can take 2 pills/day (1 in am/1 in pm) and I get no headaches or jitters. 2 at the same time made me anxious, might be fine for someone who does not have other sources of caffeine (I drink a lot of coffee). I used this last 4 weeks of prep and felt like it definitely helped with fat loss and energy levels.

Gives me a lot of energy, didn't see much difference in the body fat burning.

D4 is a great product in my opinion BUT it took a little over a week for me to start feeling anything. I was taking "Ripped Juice" but I was experiencing jitters...

srp6774's Rating

Mixed feelings on this product. I take 2 pills twice a day, once when I wake up and again about 6hrs later (noon). The thermogenic piece of this supplement is good and bad. It is good, because i do not sit in the office drenched like i have done on other products. But then its also bad, because it does not seem as potent. The main reason I am giving it a 7, is because it worked very well for me as an appetite suppressant.

I dont feel anything with this product.... It does not give me any extra energy, does not suppress my appetite... nothing...
