Cellucor Super HD Fat Burner Review

Super HD Isn't Great

Super HD uses a lot of ingredients that don't really do much at all to help lose fat, there's some diuretics in there like dandelion, but water weight isn't what most people are looking for in something that markets itself as a fat burner. 

It does have a reasonably large dose of caffeine at 160mg meaning that you will of course at least get the benefits of caffeine, in that Cellucor Super HD will result in some appetite suppression and weight loss, but seeing as this is in other better fat burners at the same price point like Instant Knockout, that's not something to recommend it. 

Beyond that we have capsimax, which has a mild thermogenic boost, we're talking a couple of percentage points, and only if dosed correctly, which is unlikely based on the capsule size and it being listed as the smallest ingredient, even if the proprietory blend doesn't give us the exact number.

Other than that we're left with ingredients that haven't had human tirals or don't actually work for weight loss. It also misses out on some of the better appetite suppression ingredients like glucomannan (which swells 50x larger in the stomach and as a result makes you feel less hungry).

We don't recommend Cellucor Super HD.

Customers Cellucor Super HD Reviews

Reviews of fat burner products are typically divisive given all of them require effort and discipline on the part of the consumer to be effective. It's not enough to just pop a few pills and hope the weight will fall off. It requires a controlled diet and regular, intensive exercise.
Plus, everyone reacts differently to weight loss products such as thermogenic fat burners. Some people will take to certain ingredients and formulas more than others. 

For these reasons, it is unusual to see any thermogenic fat burner enjoy an average four-star rating from more than 1,200 reviews on Amazon. This leads us to presume, with near certainty, that the majority of these effusive five-star reviews have been paid for. The fact that the one-star reviews are written more naturally and are voted the top responses underlines this conviction. 

Of the Cellucor Super HD negative reviews, many warn of other customers who are experiencing depression or anxiety from using it. Several reported increased irritability and lowered mood when using Super HD that then subsided when they stopped. 

Others complained of the product's high caffeine content, which may cause insomnia and jitters in those with low caffeine tolerance.
It's a similar story on the manufacturer's website, where other Cellucor Super HD side effects are reported. There are only 76 customer reviews but all bar three are positive. The negative ones detail the side effects it caused which include headaches and nausea. 

Verified reviews of Cellucor Super HD provide a more nuanced take on the product. In essence, most agree that it has some thermogenic fat-burning properties but that its energy-boosting claims are a little suspect and that is likely to cause side effects in many of its users. 

Cellucor Super HD Review Conclusions

As indicated at the start of this review, there is a disjoint between Cellucor Super HD's customer reviews and those of verified reviewers. In our opinion, the majority of the positive customer reviews of Cellucor Super HD need to be taken with a pinch of salt. Put simply, this is an average thermogenic fat burner that hides behind a proprietary blend and relies too heavily on high caffeine doses to boost energy and suppress appetite. This is not the most effective or sustainable approach. If you're looking for a thermogenic fat burner that naturally suppresses appetite and boosts energy, then we advise you to take a look at Instant Knockout Cut.

Instant Knockout contains proper doses of the functional ingredients in Cellucor and most notably glucomannan which is the safest and most effective way to suppress appetite (it swells 50X larger in the stomach, making a dose about the size of a bagel and is functionally 0 calories). On top of this, they contain higher doses of natural energy-boosting ingredients rather than just swamping their products with caffeine.
