MusclePharm Shred Sport Fat Burner Review


Initial Thoughts:

This looks like a genuinely effective product if the branding and marketing on the label is anything to go by. A lot is talked about their studies and the key features. However, all the studies in the world will not matter if the ingredients are not adequate or adequately dosed.



READ: See What The Best Fat Burner Is

L-carnitine – Acetyl-L-carnitine helps the body produce energy. It is important for heart and brain function, muscle movement, and many other body processes. It is a very popular supplement and widely proven to be active drugs for the therapy of symptoms associated with male aging. Any fat loss tends to be associated with the extra energy provided by this compound which in turn increases exercise. However, any other real fat reduction seems to be limited to elderly people.

Theacrine (1,3,7,9-tetramethyluric acid) – An alkaloid molecule which can be seen as a structurally modified version of caffeine. However, although it is similar to caffeine whereby is a sedative effect at relatively low doses, but where this sedative effect with caffeine is at an impractically low dose with theacrine it is the dose normally consumed by tea.

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.

Vitamin B12 – B12 fights fatigue, muscle wastage, boosts mood, cognition and is vital to many bodily functions including metabolism and food digestion. So to put it bluntly, we need this for smooth operation and be able to smash those workout sessions which in turn helps you burn fat and lose those unwanted pounds.

Caffeine – It stimulates the central nervous system (CNS), heart, muscles, and the centers that control blood pressure to give you an extra boost and hit that PB. This is found in Instant Knockout which we massively rate.

L-Carnitine Tartrate –  Supplementation of L-carnitine does not burn fat unless the individual is deficient in L-carnitine.

Capsaicin – The ‘chilli’ in chilli peppers, has thermogenic effects which raise the metabolism to burn more calories.

Dandelion – There’s many uses for dandelion, however, there’s no real evidence to suggest it works for any of them.

Sulbutiamine (Vitamin B1) – This appears to ward off fatigue, 400mg daily seems to be the required dose.

Niacin (Vitamin B3) – All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which the body uses to produce energy. These B vitamins, often referred to as B-complex vitamins, also help the body use fats and protein.

Fucoxanthin – This looks to be a fat loss agent, however, only one human study has been performed.


Take up to 4 tablets daily. 2700.02mg daily.


There are 7 good, proven ingredients available to us here. And, unlike many fat burners we have recently reviewed, this doesn’t seem to stray from the intended goal which is fat burning and nothing to do with cognitive function or a pre-workout.

The majority of these ingredients will help to stimulate fat burn and provide the energy required to exercise more.

There is also no proprietary blend here masking the exact content of each ingredient.


As good and some ingredients are, vitamin B1 is dosed by half as much as the recommended amount and Theacrine isn’t a very usable ingredient in these doses or weight ranges.

There is also only one study on humans regarding fucoxanthin which raises a number of questions regarding effectiveness and safety.

Dandelion is great for rabbits, not so much for us.

There is much less caffeine and green tea here than in the best fat burner on the market.

My Review Conclusion:

Whilst we are impressed by the focus on MusclePharm releasing a fat burning product and not trying to capture all markets, and being impressed with a distinct lack of proprietary blend, there are still a number of issues surrounding certain ingredients mentioned earlier. That said it is on the right track and does present itself as a good product, however, this doesn’t quite reach the heady levels of the #1 fat burner on the market today.

My score:
