Extreme Labs XXL Rebelled Testosterone Booster Review


Extreme Labs XXL Rebelled is a strong looking male testosterone booster. The product contains a blend of synthetic and natural testosterone boosting ingredients. Promising to increase levels of free testosterone in you. There’s a good set of ingredients in this product, with most of them being all natural. It’s priced fairly reasonably for 120 capsules too. Question is, will it have you making big gains?

 


Core Ingredients

This product does have a fairly strong ingredients profile. However it is a proprietary blend, so there is no way you know the amounts of what you are taking. This is an annoying tactic used by companies to protect their blends, or hide the fact it’s mainly made up of the cheaper less effective ingredients.

5-Methyl-7-Methoxy-Isoflavone

There is little to no evidence available to actually prove this ingredient as a testosterone booster. It has been used by bodybuilders for some time, however that doesn’t particularly make a strong case for it.

Sarcosine

Generally sarcosine is used to treat depression and other mental illnesses. However in the case of Extreme Labs testosterone booster, it’s used to improve cognition through your workout. This is a fairly solid addition to a bodybuilding product, however it has no direct influence on testosterone levels.

D-Aspartic Acid

D-Aspartic acid is a crucial ingredient if you are wanting to improve performance and enhance recovery. This amino acid has been proven to directly influence testosterone release in the pituitary gland and testes. This is absolutely essential for any testosterone booster.

Zinc

Zinc is a mineral that is absolutely vital for normal bodily function. Regardless of what you do, you should be supplementing zinc. The benefit of having it in a testosterone booster is that it’s vital for the release of the luteinzing hormone. This hormone is important in the production of growth hormone and testosterone in you, so again, it’s important that you get this in any testosterone booster.

Vitamin D3

D3 is known as the sunshine vitamin. Supplementation of vitamin d3 is absolutely crucial and will increase testosterone levels, but also increase metabolism too. Numerous scientific studies have shown this link, so it’s crucial you are supplementing D3 if you are wanting to optimize testosterone levels.

Bulbine Natalensis

Originally this is a herb from Africa. However some studies have shown it can be fairly toxic when supplemented. There is some evidence to support it’s role in testosterone production, however there is also potential for some side effects.


Extreme Labs XXL Side Effects

Because this is a proprietary blend there is a high chance of their being side effects from poorly dosed ingredients. For example, anything over 2500mg of DAA will cause some stomach upset through the day if not taken properly. This is the same with anything over the recommended dose of bulbine natalensis, which can be harmful over 700mg.  Check your tolerance before supplementing the full serving.
