cellucor d4 review



Fat burning supplements generally tend to fall into two categories. There are stimulant fat burners and non-stimulant fat burners. Personally I think this is a very good thing, and there’s plenty of room for both. On the one hand, some people are opposed to taking stimulants because they don’t like the way they can make them feel jittery, uncomfortable, and out of control. On the other hand, some people love that feeling of motivation and almost urgency to get moving and get working out that stimulants provide. Recently Cellucor updated their line of products calling it G4, meaning fourth generation. And Cellucor D4 Thermal Shock is part of that mix.


Cellucor D4 Thermal Shock is a stimulant fat burning supplement that takes your energy to new levels while it increases your caloric burn and keeps you from sabotaging all your progress when you get to the buffet table. You get the adrenaline rush you need for your P90X or CrossFit workout, your focus is laser sharp, and you don’t jitter or crash like you do with other fat burners. In fact, the energy goes on and on along with your jacked up fat burning metabolism.


Cellucor D4 Thermal Shock Ingredients

As far as supplements go, it’s really all about the formula. So here’s a quick and dirty breakdown:


  • Cellucor D4 Thermal Shock Review 3Amla Fruit Extract gives you that great adrenaline rush of energy and keen alertness. It comes from the Phyllemblin in Amla Fruit and it also promotes vasodilation for better pumps.  Amla fruit also demonstrated lipid lowering properties in human volunteers. (1)
  • White Willow Bark Extract is a great source of Salicin which turns up the heat on caffeine, making it even more thermogenic than it already is.
  • Octopamine HCI breaks down fat cells while preserving lean muscle. This is the core of the thermogenesis in Cellucor D4 Thermal Shock and it increases the effectiveness of the caffeine.
  • Yohimbe Bark Extract is a vasodilator, increasing the amount of blood that flows through your blood vessels. It stimulates energy and delivers much needed oxygen and nutrients to your muscles during your workouts.
  • Caffeine is obviously a CNS stimulant that keeps you alert and energized. It also contributes to thermogenesis.
  • Sclareolide from the Clary Sage plant increases muscle energy.
  • N-Acetyl-L-Tyrosine is a precursor to epinephrine, dopamine, and norepinephrine which increases the release of Human Growth Hormone.
  • Evodiamine increases metabolism and boosts energy. It also increases your core body temperature so you’re burning more calories at rest.
  • Passion Flower Extract eases anxiety and minimizes jitters and that crash that stimulant weight loss products often cause.

How To Take Cellucor D4 Thermal Shock


The recommended dose is 1 Cellucor D4 Thermal Shock capsule in the morning and 1 capsule in the mid afternoon. You always want to start off taking it with a little food to make sure your system can handle it well. You should cycle this fat burner on for 8 weeks then off for 4 before starting a new cycle.

Cellucor D4 Thermal Shock Side Effects


I’ve definitely heard talk of people feeling jittery and nauseous when taking this. Several have likened it to being high on speed. I know there are some guys who like this kind of feeling, but generally, I’d have to say it’s not exactly good for you. It could be the Yohimbe. Lots of people don’t tolerate it very well, so you’ll want to be cautious when you’re first starting out.


Cellucor D4 Thermal Shock vs Super HD


Super HD has 10mg more caffeine while D4TS is very Yohimbine heavy. When it comes to fat burner — D4TS; if you are looking for a Cellucor Thermogenic,  Super HD is the way to go. Both are 2 totally different products, but fat burning wise D4 Thermal Shock heavier in yohimbine (D4) and the Super HD has a thermo blend.  It is probably not a good idea to take both at the same time.

Cellucor D4 Thermal Shock Testimonials


There are many favorable Cellucor D4 Thermal Shock before and after results on the forums.  Here are some that we found:


“Cellucor’s D4 Thermal Shock fat burner is excellent. I have sampled many fat burners but after a serving of D4 i was hooked this product gave me awesome all day energy and no jitters. If your looking for SERIOUS results then Cellucor’s D4 Thermal Shock is the hands down the #1 fat burner around!!!”


“So I took this product with the anticipation that it would be a dimmed down version of Super HD. This assumption was entirely wrong. I take 2 in the morning and can fast for more than 6 hours without craving. Would entirely recommend for anyone looking to lose weight fast!”


What Does Cellucor D4 Thermal Shock Stack With?

If you’re into a serious weight loss phase of your program, it’s a good idea to stack Cellucor D4 Thermal Shock with a non-stimulant weight loss supplement like Cellucor CLK.  The combination, along with your healthy eating and aggressive workout schedule will give you insane weight loss results. It also stacks well with Cellucor P6 Extreme, or any testosterone booster that works. This combination will help you get that lean and shredded look.


Our Cellucor D4 Thermal Shock Conclusions

It’s not for the weak at heart, but Cellucor D4 Thermal Shock does work. Some people just don’t like the way caffeine and other CNS stimulants make them feel. As long as that doesn’t describe you, you’re good to go. There’s no question that Cellucor D4 Thermal Shock can help you lose weight.


You can buy a 15 day supply of Cellucor D4 Thermal Shock for $39.99 or a 30 day supply for $69.99. Cellucor also has a 30 day money back guarantee so you have very little to lose (besides the fat).

  • Can you give me advice on taking Winn50 n Clen. I\’m 42yr old male good shape. Very active workout 4-5days week. Was taking Cellucor D4 fatburner

    • Hi Fred,

      I am very familiar with Cellucor Supplements. They are not bad, but they cater GNC other stores and that means they are over priced and underpowered.

      If you are looking at the anabolic research Winn 50 and Clen, you should be fine. Only one of them contains DHEA so you can expect a boost in testosterone while cutting. You would take 2 capsules of Clen and 2 capsules of Winn 50 daily. There is no hard rule for this, but 1 of each 2x a day would work. Or you could spring for a stack like the Anabolic Research Summer stack which offers 2 more supplements to hit your body from more angles. you can find out more in the articles below.

      Anabolic Research Winn 50
      Anabolic Research Clen
      Anabolic Research Summer Stack

      Another company that makes great products is Crazy Mass Supplements. They make Winstral and clen. Its an alternative Anabolic Research. You can check out the links to the articles below to educate yourself and make an informed decision.

      Crazymass Winni
      Crazymass Clen
      CrazyMass Cutting Stack

      I hope that helps. Let me know what you decided and how you made out!
