What To Expect From Hydroxycut SX-7 Black Onyx!

Hydroxycut SX-7 Black Onyx is targeted towards users who want to lose weight & get into shape. It claims its mixture of natural ingredients will cause your body to reduce its overall weight through a process called fat burning. Putting this in more simpler terms for users who do not know what a fat burner is:

  • Speeds up metabolism to improve weight loss
  • Boosting energy levels to improve calorie burn

If a supplement can achieve the two points above in a safe manner then the Hydroxycut SX-7 Black Onyx supplement would be a good choice. If it causes side effects and user reviews a poor then this supplement should be sent to the bottom of your list!


One of the first things we look at is the ingredients in the formula. Are they safe? Do they provide any medical or scientific evidence that suggests the claims made by the product?

These aspects of the review carry the most weight because if the foundation the product is built upon does not work, then the supplement cannot achieve its desired result!

Here is the full breakdown of ingredients used in this formula:

Caffeine Anhydrous. One of the more commonly used ingredients used in fat burners because it keeps you focused and alert. But the effects of this ingredient does not last very long. We have used this supplement before and can say that the crash can happen quick and wanting. Much like your morning cup of coffee!

Coleus forskohlii. No evidence suggests it causes weight loss or helps the user burn fat. But, it does improve blood flow and help users with asthma relieve their symptoms. Coleus forskohlii is a new one for us as a fat burner because we have never known it to be used in this type of supplement.

Green Coffee Extract. Much like Caffeine Anhydrous, it keeps you alert and active for a short period. Green coffee does have backing from scientific research that claims of reduced glucose in your liver. Which leads to more significant weight loss over time because of less Chlorogenic Acid build up.

L-Theanine. BCAA that is proven to lower blood pressure and making other ingredients work better because it delivers them into the bloodstream quicker. But is also used to treat anxiety and depression in Asia through traditional medicines!

Satsuma Mandarin Pulp. Packed full of B vitamins, magnesium, zinc and dietary fibers that help you stay healthy and active when dieting.

Ingredients Breakdown

The Hydroxycut SX-7 Black Onyx ingredient list points us in favor of a product that supplies you with higher energy, stamina, and focus. These are the main aspects of any fat burner because this will lead to a better level of metabolism due to you being much more active!
