MuscleTech Hydroxycut SX-7 Black Onyx Non-Stimulant Fat Burner Review

MuscleTech Hydroxycut SX-7 Black Onyx Non-Stimulant Fat Burner Review First Look:

As I chomp away on my fourth sandwich of this afternoon it may come as a surprise that I am on vacation in 48 hours. Yet I just keep eating.

However, last night I was lifting some heavy weights – a new best of 192.5kg/423.5lbs on the isolateral bench press.

Clearly that recovery needs fuel, or that is exactly what I am telling myself and you right now.

And, once again we are face to face with another MuscleTech fat burner.

The last one we tried was pretty good (read review here) with every single ingredient offering benefit, it only downfall was that it could have included a few more proven ingredients to make it a podium finisher.

Yet again, in typical MuscleTech fashion we are launched at with another fat burner from their Black Onyx range…will this onslaught of products ever end?!

So blink at the wrong moment and you will pick up the wrong bottle, these are all near identical and an absolute pain in the ass to distinguish between.



Vitamin B12 (cyanocobalamin) – Gives you more energy and boost your metabolism, helping you shed unwanted pounds. Ensure you are not deficient in Vitamin B12 so you can do that quick 10 miler at 5am…

Vitamin B6 – Using it in its most natural form, pyridoxine, B6 is an essential nutrient to raising the body’s metabolism and aiding the fat burning process. B6 is key in fat burners such as Instant Knockout.

C. Canephora Robusta (Green Coffee Extract) – Evidence from research has indicated that the consumption of caffeinated coffee can lead to some reductions in long-term weight gain.

These weight loss results are likely to be due to the known thermogenic effects of the caffeine.

This is found in the best fat burners such as Instant Knockout.

Euphoria Longana (Dimocarpus Longan) – There’s not enough evidence to suggest Longan fruit as a recommended option for anything although it might be a useful functional food to ingest for cognitive purposes.

Morus Abla (White Mulberry) – Lots of potential for anti-diabetic properties, reduction of the absorption of carbohydrates and maybe even cognitive enhancement but none is tested and confirmed on humans.

Melissa Officinalis (Lemon Balm) – This may, but it is not entirely conclusive support feelings of calmness and relaxation.

L-Theanine –  Beneficial for stress reduction, decreasing generalized anxiety, and reducing the severity of insomnia. If caffeine is present too, IQ scores have known to increase – so grap a cup of coffee, quick.

BioPerineThe extract of piperine, called BioPerine®  in the patented form, has been clinically tested in the United States.

BioPerine®  significantly enhances the bioavailability of various supplement nutrients through increased absorption.

FucoPure (Fucoxanthin, Undaria Pinnatifida) – There’s reasons to believe there are many health related benefits by supplementing Fucoxanthin which is also known as seaweed, however, the bio-availability in humans is low.

Yet, over a period of 16 weeks 5mg per day may help fat loss.



The advice is to take 2 capsules daily which provides a positively generous 994.612mg daily.

This is a low daily dose when compared with the best fat burners which tend to offer in excess of 3000mg.

Effects & Benefits:

It is refreshing to see a further product from MuscleTech that isn’t loaded with about 25 different ingredients. Maybe they’re realizing more doesn’t mean more effective.

So to see 9 ingredients looks positive, as long as they’re all useful.

So what do we have?

At best we have 6 effective ingredients.

More realistically we have 4 proven ingredients.

3 effective and proven fat burners, 1 to help cognitive performance.

1 which helps our body absorb the nutrients.

So, in effective, we have 3 fat burning ingredients which are B6, B12 and Green Coffee, all of which are found in the best fat burner called Instant Knockout.

when it is broken down further, that doesn’t looks such a good figure. Just one third is effective for fat burning.

If we were to be optimistic one could say that Undaria Pinnatifida is also effective as a fat burner, but results are limited and a bit cloudy.


The overall dose per day is low and less than even one third of what we have come to expect when the best fat burners come in to consideration.

Plus, having just 3 solid fat burning ingredients in the whole supplement is not very good, we would expect at least 8,proven and effective ingredients.

That means we have 3 ingredients which offer no proof that they are effective and a further ingredient that may work over the long term…again not entirely conclusive results.

L-theanine is good for your IQ or reducing anxiety but I am here to help burn away these sandwiches not win a Nobel Peace Prize.

And how much do we need to pay for this lack of effectiveness? $60.00!

MuscleTech Ultra Carnitine 3X SX-7 Black Onyx Fat Burner Review Conclusion:

This does not improve upon any of the other MuscleTech products. While it is sensible to see a more concentrated ingredient profile all of those ingredients need to work. They need to stimulate fat burn.

Only 3 are conclusive to stimulate fat burn in this product, at a stretch 4 can.

However, 4 out of 9 is less than 50%. So what’s on offer here is a fat burner whereby less than 50% will help fat burn.

That is not good.

Take a look at the best fat burner on the market which takes the 3 proven ingredients found in this then builds upon it with further proven and effective ingredients.
