I needed energy. My life gets busy. It gave me plenty of energy! I felt the "thermal" effects. I felt warm but it wasn't uncomfortable and that's what I was worried about. I eat healthy and work out 3 times a week. The extra energy motivated me to work-out harder, longer. I was steadily losing weight but this product increased my weight loss. My metabolism increased but my appetite wasn't as high. I ate several small meals through-out the day. I would not recommend anyone to add caffeine to your diet while using this product if your tolerance isn't very high. I did without thinking and I had the jitters pretty bad but that's not negative on D40 it was my mistake. Great product. I recommend.

After college baseball I got confortable in a relationship and gained 30 pounds! I've always stuck with working out but my diet was the one that was killing me. With vacation a month away I decided to kick it into gear and get in shape for beach. I knew I could get to where I wanted to be by just diet and exercise. I realized I was going to need a little help. Well after trying and loving Cellucor C4, I gave Cellucor a try again. And once once I was not disappointed! In a months time I went from being 6 foot, 215lbs to 195 pounds. I am going to give you a break down as far as the effectiveness value and everything, but before that I would like to mention that I took the weight loss stack that consist of D4 Thermal Shock, T7, WS1, and L2. So basically I will give you my thoughts on the STACK

Dosage/ size of pill: I took the recommended dosage on the bottle and was able to lose a lot of weight. I don't think there is a need to up your dosage with this stuff because it is pretty potent. As far as the size of the capsule and swollowing it, it's not bad at all. It's an average sized capsule and goes down no problem ( all the capsules are same size in this stack)

Value: D4 is priced around 70 dollars for a 30 day supple, i think that this is a little over priced. If you end up buying the stack you will get a better value, and get your money's worth.

Effectiveness: I was a little disappointed in the energy it was suppose to give me. I'm not saying that I didn't get any energy from it, but I expected more. I am used to VPX Clenbutrx, after taking it I had bursts of energy. Maybe bc it tasted like ass, idk haha. Anyways the energy from D4 was not there for me as much as I wanted

Overall: I would definitely recommend anything from Cellucor, I have never been disappointed with their products. I lost weight with D4 and gained lean muscle. The weight loss stack is AMAZING, but if you are just looking for a single fat burner to get that stubborn fat off, D4 should be your choice

OK, Third review for me - so bare with me here guys.

First off I'm a huge Cellucor guy. This product was a little too much energy for me. I had started with the regular D4 and it worked great, went to this and here's what i noticed.

How it works:
What i noticed that most labels of products that tell you to start with a half dosage usually more or less jurt try to make you feel like you're getting something hardcore, and this one is no different, EXCEPT it's true. I took just one pill in the AM with a protein shake (BioRhythms Whole gains). About 20 minutes later I started to get the rush. Let's just say i'm glad i only took one pill as the energy I was geeked out of my mind. I 100% noticed over the next few days that I was sweating much more that usualy, and felt great while working out. after a few days i bumped it to the 2 morning 2 afternoon dosage. WOO HOO is all I can say - lol. It was a little too much energy for me. I'm sure a lot of you guys would be fine with it, but myself I just had way too much energy. I wanted to clean the house, take out the Garbage, clean dishes, work out 3 times, it was just too fricken much. But positive thing was i def dropped more weight, and again, I was a sweaty mess while working out.

Price:
I was able to get this for $40 for the 120 capsule bottle, so for me it was well worth the money, at "retail" of $70 i think it is, not so sure about that. Iw ould say if you can get it for a good deal, try it out, if you can handle the energy it will most likely work GREAT for you.

Overall:
Like i said, I was sweating much more, energy was amazing. I can only give one warning, made a mistake of taking this ONCE without food because i was rushed. HUGE mistake. Upset stomach, and felt like i was about to have a heart attack. I cannot give an exact number og lbs i've lost since i'm coming back from 9 month shoulder injury - but in 2 months i'm down to a 34" pair of jeans from 40" - but my weight actually went from 245 to 252 - with getting my lost muscle back, and never got my BF% done.

If you ask me - get it at a good price, give it a shot - take it with food.

Hope this was a better review - i'm open for suggestions on how to improve my reviews. Please feel free to reply to let me know if there was any more information you would have wanted.

I'd just finished a bottle of this and thought I would share some results. For starters, the recommended dosage is one pill prior to workout. I'm used to thermogenics and within a week, I toke two. The first time I took this, I felt Jittery with an elevated heart rate. This occurred within twenty minutes. As I was getting dressed in the locker room, I felt jumpy and really full of energy and motivation. During my warm up cardio, I sweated like crazy. It really gave me that boost to push the weights as I trained. I felt stronger and more pumped and ready to take on everything. After the workout, I felt slightly nauseated but drank a protein shake with creatine mixed in and the feeling went away.

I would say that this is a very effective pre-workout thermogenic. It got me pumped and Motivated to get going in the morning. Except for some nausea and occassional light-headedness if taken on an empty stomach, I didn't really experience bad side effects. You will sweat while taking this. Within minutes of working out, my shirt is drenched. I have noticed that as I neared the end of the bottle, the effects weren't as strong, but I am assuming that it's just my body getting used to the pills.

I work out 5-6 days a week and within a month have added muscle and definition to my body. I must say that this does make me extremely hungry, so as an appetite suppressant, it didn't really help me in that area.

I'm going to cycle off of this and then go back to it again later.

I didnt lose any weight, went thru 2 cans of the stuff... its not for everyone, not for me, didnt do anything,but make me jittery, no weight loss at all, following diet and 4 day a week workouts. Sorry Cellucor.

This product is not worth the amount its being sold for. It does help you loose some fat but, not what is expected from a fat loss pill. The results that you get from this you can also get just by eating right and exercizing. It does give you energy as well as jitters, over all I wouldnt recomend this product

This product has not helped me lose a pound. It did give me energy but the side effects were bad. I always felt like i had to pee to the extent I thought I had a uti. I drank tons of water and worked out. I cant focus on anything, I felt sick and actually felt more hungry sometimes and cold chills,dizziness. Do not take these pills!!

I have always had fat around my midsection. Even in high school when our coach made us do an incredible amount of sprints and I dropped down to 185, friends on the team told me that I was the fattest skinniest kid they know. Now in college, I was determined to get into the best shape I could. I know that there is no miracle weight loss pill, but I just wanted a little extra something to help and D4 seems to be that. Keep in mind, I have also cut carbs completely from my diet, I began drinking 2 cups of coffee in the morning, take 6 cayenne pepper pills throughout the day, eat 3 small meals and 2 snacks every 2-3 hours, and do 45-60 minutes of cardio before breakfast. I have done this for two weeks now and have lost 14 pounds. I am 6'4 and weigh 212 now. I also work out everyday in the afternoon around 4pm or 8pm. I have done this before, but have not lost as much weight as quickly. I have had no side effects, no jitters, no cold spell, no chemistry unbalance. I just feel that this product cost too much and its probably not for everyone. You may feel a little sick at times if you take 2 in the morning like I do(and 2 in the afternoon), but drink milk right after you take it. It feels better. Hope this review helps.

Ok, so after months of seeing praise (and high prices) of Cellucor supplements, my prayers were finally answered. A 20 dollar coupon from bb.com. I was just about to start cutting, so i jumped on the now great price I could get thermal shock for. Was I disappointed...
Effectiveness: For use as a fat burner, I believed that this accompanied by a strict diet of carb cycling and post workout cardio would yield incredible results. After one whole bottle (1 serving before breakfast, 1 serving pre-workout) i was extremely bummed by a lack of dramatic effects. Energy was decent throughout the day, but i feel that the results achieved were similar to a non-thermogenic cutting cycle.
Value: Using a 20 dollar coupon, this was a very decently priced supplement. However, this is in NO way a product worthy of 60 dollars. Don't fall for the Cellucor gaudiness, they are just a shiny version of MuscleTech (for this product at least)

This product will infuse courage. I feel like I can kill a coyote with my bare hands. It gives you mental focus like that of a water buffalo, sexual tenacity like that of a succubus, and determination like that of a Liger. Be forewarned, only take this if you want to feel invincible...and lose some weight doing it.
