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.
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.
the doses of some of Cellucor Super HD's ingredients are not revealed. Instead,
on top of 160mg of caffeine and 150mg of green tea extract, Cellucor's
effectiveness lies in a 193mg proprietary blend.
the exact doses makes it harder to trust Cellucor Super HD's effectiveness, but
we will nonetheless look at the ingredients in detail and consider whether it
support's the manufacturer's claims that it burns fat, boosts energy, and
While we don't know their exact proportions, here are the ingredient contained in Super HD's Thermogenic and Sensory Blend and as most of the ingredients aren't much use at all then it doesn't matter all too much in this case:
N-Acetyle-L Tyrosine - N-acetyle-L tyrosine is an amino acid that a study in rats showed may inhibit weight gain, but this research has not been replicated in humans. 
Amla Fruit Extract - Amla fruit extract, otherwise known as Indian gooseberry, is high in antioxidants but research suggests the dose required to feel weight loss benefits is significantly more than what Cellucor Super HD contains. 
Dandelion Root Extract - The presence of dandelion is another reason why many users need to pee more frequently as it is a well-known diuretic. Thanks to these properties though, it can be of use as part of a weight loss regime. 
Yohimbe Bark Extract - Yohimbe is a tree that's been used for centuries in western Africa primarily to improve sexual performance. Modern research indicates that it may help to burn fat but it does not appear to support muscle growth or athletic endurance. 
Capsimax Cayenne Fruit Extract -Capsimax is a proprietary blend of pepper extracts that research suggests may assist with long-term weight loss by burning excess fat and suppressing appetite. 
Toothed Clubmoss Extract - While the manufacturer claims this is a powerful thermogenic fat burner, there is little research into its effectiveness.
Rauwolfia Root Bark Extract - Rauwolfia is included for its mood-enhancing properties, with one study indicating it is effective in the treatment of hypertension. 
Caffeine Anhydrous (160mg)
Everyone knows that caffeine boosts energy and focus. The 160mg dose, akin to three strong cups of coffee, is sure to do this but comes with side effects for many. What's more, the body quickly builds tolerance to caffeine so it is necessary to cycle products containing a lot of it.
GreenSelect® Green Tea Phytosome (150mg)
Research suggests that green tea extract helps the body to oxidise fat, although these benefits are more pronounced at rest than during physical activity. 
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.
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.
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.
