MuscleTech constantly have new products coming to market. Hydroxycut is their popular fat burning product. In this review we will take a look at if the SX 7 Black Onyx version is really worth that massive price tag.

Fat burning is something that needs to be pretty exact, as do the ingredients and dosing in popular fat burners.

This is an all natural product which is good, meaning it can be supplemented for longer and should have limited side effects.

With so many proven fat burners on the market though, with Hyrdoxycut SX 7 Black Onyx be the newest and best fat burner on the market??

Let’s take a closer look at this good looking product to find out…

MuscleTech Hydroxycut SX 7 Black Onyx Core Ingredients

Fat Burning Ingredients Index

The ingredients list in MuscleTech’Ss Hydroxycut SX 7 Black Onyx is actually fairly basic. Especially given the cost of the product itself.

It uses a fairly standard looking blend of stimulants to promote a faster metabolism more than anything.

Whilst most of these ingredients will have some decent effects, there’s a few in here that are in lower doses and will not compete with what you expect from a premium fat burner.

Let’s take a closer look at the main ingredients that will get you results.

MuscleTech Hydroxycut SX 7 Black Onyx Ingredients

Coffee Bean

Generally coffee bean etc has a similar effects to caffeine. It works similar to Green Coffee.

This helps in that it reduces the absorption of blood sugar by the intestine. It then inhibits an enzyme in the liver which means that less glucose is released into the bloodstream. So with less glucose readily available the body will burn fat first.
This is a proven ingredient and essential for those looking to burn fat.


Caffeine is a staple supplement to modern day life. It is a highly effective stimulant in how it boosts the metabolism, mobilises fat to be used as energy and suppresses appetite.
As well as this it can boost the effects of other metabolism boosting products, such as green tea or bitter orange.
It has long been used by athletes, and non-athletes alike, in order to increase alertness, endurance and longevity.
This is essential for a fat burner. You need around 250mg-300mg dosed evenly through the day for best results.


This will aid with focus and also take the edge off stimulants, allowing the energy to be channeled and also keeping cortisol (stress hormone) levels lower.

You want 200mg+ for this to be truly effective.


Yohimbe has been shown to help increase power, inner strength and vitality. This is largely due to its effect upon the libido, both male and female.
It is also particularly useful for suppressing appetite. This effect combined with its ability to target stored fat makes it a commonly used supplement for fat loss.
The jury is still out on how effective it is however, with some studies showing unwanted side effects and limited benefits.

MuscleTech Hydroxycut SX 7 Black Onyx Dose

The dose of Hydroxycut SX 7 Black Onyx is a little low in terms of what a good fat burner should be.

For best results when you are burning fat you need 3-4 capsules per day. Whilst the amount of stimulants in a single capsule of this version of Hydroxycut is ok, it’s ultimately going to lead to energy crashes if you don’t have enough servings.

Remember to try and take your Hydroxycut SX 7 Black Onyx as spaced as possible and avoid taking 2 capsules at once as this may do more harm than good and cause some side effects.

MuscleTech Hydroxycut SX 7 Black Onyx Side Effects

The side effects from the stimulants in this product could lead to unwanted side effects.

These will include but aren’t limited to energy crashes, headaches and potentially nausea.

There are better and more balanced natural fat burners out there that eliminate your chances altogether by using a carefully measured blend. This is how you seriously burn away unwanted fat.

MuscleTech Hydroxycut SX 7 Black Onyx Review Conclusion

Generally this product is fairly expensive for what you are getting.

Whilst there is some solid ingredients in here that can help with fat loss, there are a few that will get you limited results.

It’d be good to see Chromium and Green tea in here, as these are two of the most well researched and effective fat burning ingredients.

MuscleTech seem to be releasing products without much thought in terms of the ingredients. If you seriously want fat burning results, there are better products out there.
