We additionally examined numerous dieter comments and customer responses from around the web. Finally, we condensed this information in order to give you the bottom line.

What is Cellucor D4 Thermal Shock?

Firstly, Cellucor D4 Thermal Shock is marketed as a high-energy fat burner. The ingredients are amla fruit extract, caffeine (150mg), white willow bark extract, octopamine hcl, yohimbe bark extract, evodiamine sclareolide, passion flower extract and n-acetyl-l-tyrosine. It is claimed to help improve mental focus, control appetite, heighten energy levels and burn off unwanted fat. You simply take one capsule in the morning and one again in the mid-morning (along with 8-12 ounces of water).

Cellucor D4 Thermal Shock has been available since at least 2010 and it can be purchased online. This supplement contains natural ingredients and there are some customer testimonials posted on the official website, but read on…

Adverse Effects – “Something to Consider?”

The Cellucor D4 Thermal Shock side effects are our first concern. According to our Research Editor, “The Yohimbe Bark Extract in this supplement can lead to unpleasant reactions and even heart problems, especially when combined with caffeine.”

One user stated, “Gave me severe headaches every time I used it. The right lobe of my brain hurt and it did not subside for close to 6 hours. I also had this nauseous feeling throughout the day.”

“It made my heart race and I sweated like I had just ran a marathon,” said another customer.

Another Concern – “Plenty of User Complaints”

There are quite a few customer complaints posted on dealer websites such as Amazon. In fact, one person revealed, “My fingers started tingling then I couldn’t move them…then I had a full panic attack. I thought I was having a heart attack because I’ve never experienced something this scary happen to my body. I got driven to the emergency room and the panic attack lasted 1-2 hours.”

Another individual commented, “Not a fan. They made me feel horrible!”

According to our extensive research, if there is a certain facet of a weight-loss product or diet program that is especially burdensome (adverse effects, user complaints, bad taste) the odds of long-term success are not good. This means if Cellucor D4 Thermal Shock does in fact lead to a high number of issues, this could be a problem.

Any Real Science?

At DietSpotlight, we like to see some real science that supports the weight-loss product and its ingredients. Unfortunately we could not locate any clinical research or studies that support the claimed effects of Cellucor D4 Thermal Shock. Nothing is presented on the official website. However, we do know that Caffeine can boost metabolism and focus – so that could be where the claims come from.

The Bottom Line – Does Cellucor D4 Thermal Shock Work?

Now the moment you’ve been waiting for: our bottom line on Cellucor D4 Thermal Shock. First off, we appreciate that natural ingredients are used in this supplement and there are some customer testimonials posted on the main website. Then again, we have some concerns because it’s not supported by actual science – aside from the Caffeine. Also, we have doubts about the blend in this product, because there are clear reports of side effects.

If you’d like to get rid of more pounds, then we advise you to go with a diet product that is supported by solid clinical testing, is very affordable as well and is backed by some amazing customer reviews.

Among the best products we’ve seen in 2016 is one called Leptigen. It contains a blend of four key ingredients, which have been shown in documented clinical tests to help ignite metabolism and encourage fat loss. We have not found many complaints of harmful side effects and user comments posted on the web express people are seeing excellent results.

The makers of Leptigen are so sure about their product they’re offering a Special Trial Offer, which is a positive sign.

Does anyone know where to buy D 4 ? It is discontinued. What should I replace it with ?

Hi! For more information on where to purchase this product, please refer to the Cellucor official website.

I’ve been using this for about a month with my new health plan and have managed to lose around 6kg in that time while still managing to head out for beers, do food tastings at nice restaurants and generally enjoy myself. This isn’t a miracle cure, it isn’t some magic weight loss pill and I am really being careful what I eat the rest of the time. The big plus of this pill is that it keeps me going with energy, seems to reduce hunger pangs and generally gives me the leg up I need to kick start my weight loss. This is heavy on the caffeine, so you do need to keep that in mind – I think i’m fairly desensitised to caffeine after years of strong black coffees, but if you experience any side effects remember that you need to drink plenty of water and try and have a bite to eat with it as well to help even you out. If in doubt see your doctor, but for me these certainly seem to be doing the trick for me and are really helping…placebo effect or not i’m losing the weight i want at a healthy rate and that can only be a good thing.

I just started using this product again for the second time. In 2014 I used it and dropped about 25 pounds in a month. I only used it for 1 month. It gave me the boost I needed to drop 70 pounds total in about 6 months. I did feel nauseated and clammy when I first started taking it but my body got used to it. I also added cardio and dropped unhealthy carbs for that duration. I was at around 225-230 lbs when I started and I’m a 5’10 male. When I started taking it I was very unhealthy and not loving exercise. I started using this and walking a couple miles on the treadmill. I gradually each week added time to the walking and got up to 6 miles a day then my job in a warehouse kept me moving all day long. During that 7 months I went from the 225-230 previously mentioned down to 148. My goal was 175. With all the walking the warehouse the weight kept dropping. I’ve since gained about 25-30 lbs of threat back so I’m using it again to get my energy back up and motivation to take 15 of these lbs back off. I loved this product. Nothing else has ever worked for me in the last 15 years.

Hi, i have a question. I have already started usind cellucor c4 ripped preworkout and would like start using also d4 thermal shock. Can i mix it together?

Alex, C4 is a preworkout and the other is a fat burner. Before taking either ask your doctor. After, if your goal is to build muscle, start with C4 and add D4 Thermal Shock later (slowly) once you know how your body likes these formulas.

please necessary, i want to know how many caps should take in day? and when? can i take it with eating or after ?

Before eating
Fitst 1 and after 1 month 2 caps daily

Hi Eman. For detailed product instructions please refer to product label or the official cellucor website for more information.

Yes it is effective

I feel very good after taking but after one hour i feel very bad.i don’t know why .such a bad experience.before 2 years i used it was nice.pls check the quality.

This product is great ONLY IF you take it as instructed , it’s helped me burn fat easily in the first week , you just have to have a good diet ( not a perfect diet ) and exercise regularly , drink water , I recommend eating before taking your dosage and DO NOT take two at a time , I made that mistake and it’s not pretty

can i take two caps in day? and when i take it

I have been taking this for nearly a week now, I started out on 2 pills a day but I’m
Moving up to 4 as of next week , I was a huge coffee drinker so the caffeine isn’t to bad for me, I work in a kitchen so I’m always hot, but I have noticed taking this I’m feeling a lot hotter but my energy levels are going great. I have lost nearly 5kg already and I have kept my old work out schedule ( 1.5 hours Excersise bike 4 days a week) looking forward to continued positive results

D4 will make you nauseous if you take it on a completely empty stomach, don’t starve yourself. Eat something light that will keep it from dissolving straight into your stomach lining, like yogurt or something. Drink lots of water, and eat healthier. It contains a lot of caffeine so if you are sensitive, start with one capsule in the morning. As you become more used to it, take one in the morning and then one before your workout. You need to workout 3-4 times a week or you wont have any significant results. Also, being hot throughout the day is normal, this product is designed to help you burn more calories…

So your looking for the miracle pill, that you loose weight with out putting the time in to exercise? It does not exist you know.

what happens if i took 2 by mistake?

Hi Sharon. You might feel really jittery. If you start to feel really bad, please reach out to your doctor.

Would this product be effective if I took it after eating?

Hi Anna. For detailed product use instructions please refer to label or the official cellucor website for more information.

Idk. I’m wondering the same thing. I took my first pill today and feel REALLY bad lower abdominal pains. I feel like I’m having a miscarriage– I’m a guy…

Hello Al. If you continue to have these side effects, please consult with your physician before continuing to take cellucor.

it can, i felt nausea at first but i fixed it by having my morning dose at 3:00am so i could lye back down as it goes through my system. i wake up have a balanced breakfast then workout!! See if this works for you, if not i’d discontinue until consulting your physician =)

The pill has a lot of caffeine in it which will make u pee a lot. Its normal… to me at least

I am 16 years old. I have been taking d4 for about 2 days now. Two pills a day. One before school and one after. I work out daily for the past year or 2. Ive been drinking a gallon of water a day with these pills. I feel a lot of energy and I also now stay a wake at school. I have been running farther and faster. Hopefully I can loose some weight. Guess ill just wait and see.

I started D4 7 days ago and I lost 8lb so far. I think it’s all water weight. but still I lost weight!! So far I like them!!

About to start taking these tomorrow. 5’5 female 17 years 142 pounds aiming to hit 125 asap. Wish me luck. Only gonna take one a day starting out though.

This product is quiet a mystry… Im sure it will work but the lack of sleeping drives me nuts …. im on my second day and the apetite is going downhill
