Industry giants Bodybuilding.com have always had a range of signature supplements.  Surprisingly these supplements rarely go beyond individual ingredients like Whey Protein or BCAA’s. Their latest product is a fat burner and thermogenic called Bodybuilding.com Signature Thermogenic.

The blend it uses is quite basic, but don’t let that fool you. This supplement should do what it says on the bottle. Increase your metabolism with it’s thermogenic blend.

The problem with this supplement is more to do with the cost for what you are actually getting. When compared with other top of the range thermogenics, even some on bodybuilding.com like MusclePharm Shred sport, it’s lacking a little.

Bodybuilding.com Signature Thermogenic Ingredients

You’d think that the leading supplement retailer in the world would have a supplement range grounded with some of the greatest blends and research in the industry. Surprisingly, Bodybuilding.com haven’t released a rock solid blend sure to be the best fat burner. Instead they’ve seemingly released a budget fat burner, that comes with a fairly high price tag. Quite frustrating really.

One major flaw of the blend is the lacking of proven and highly effective fat burning ingredient Green Coffee. Not only this though, the addition of Citrus Aurantium may cause alarm for some people.

It’s good to see a solid amount of caffeine and green tea balanced with amino acid L-Theanine though.

Citrus Auranthium

Contains synephrine, which is found in the unripe citrus aurantium fruit. This ingredient has been shown to directly influence metabolic rate, but another issue is it’s similarities to banned substance ephedrene. It’s because of these similarities though, it can cause unwanted side effects.

Spread evenly this ensures you are getting a good dose of key ingredients to boost up your metabolism.

One issue however is the potential for side effects. Due to the Bitter Orange extract/citrus auranthium so high there will most likely be some side effects if you supplement it.

Bodybuilding.com Signature Thermogenic Side Effects

There is a very obvious answer to this question. You can buy it direct from bodybuilding.com here. 120 capsules will set you back £24.99. This is an ok price, but it does pale in comparison to our top 3 fat burners.

If you pay a little more you are going to get a far more thermogenic blend which will jack your metabolism up even further and shred you right down.

Bodybuilding.com Signature Thermogenic Review Conclusion

We’re not as impressed as we’d hope with this bodybuilding.com fat burner. It’s got a good amount of proven and reasonable ingredients in it, but at a low dose.

One major issue is the use of Bitter Orange. The contents of this ingredient have been proven to interact with caffeine and cause unwanted side effects.

You will get some thermogenic effects from supplementing Bodybuilding.com Signature fat burner. But they won’t be as noticeable as a premium and well dosed fat burner.

Bottom line we’d have expected far more from Bodybuilding.com.
