Fat Loss and Muscle Enhancement Supplements Found To Contain DMAA

On June 17, 2013, the FDA issued a warning letter to Formulife, Inc., dba Purus Labs, Inc., following a facility inspection which found the dietary supplements Fat Smack XR Thermolipolytic, Muscle Marinade Fresh Fruit and Muscle Marinade Cherry Limeade to contain DMAA.

DMAA, which was listed on the supplement labels as "2-amino-4-methylhexane," has been linked to a number of adverse effects and is not allowed to be sold as a dietary supplement ingredient.

In April 2012, the FDA announced that DMAA is unsafe and cannot be sold as a dietary supplement. At the time, the agency had received 86 adverse event reports on products containing DMAA, which can narrow blood vessels and arteries and potentially increase the risk of elevated blood pressure, shortness of breath and heart attack. It may also be listed on labels as dimethylamylamine, 1,3 dimethylamylamine or methylhexanamine.

Fat Smack XR Thermolipolytic contains DMAA, vitamin A, vitamin C, green tea extact, Cissus quadrangularis black pepper extract, and chili pepper extract. It is promoted for fat loss.

(See's Review of Weight Loss Supplements for tests of related products and see Reviews of Vitamin A Supplements, Vitamin C Supplements and Green Tea Supplements for tests of products containing these ingredients.)

Muscle Marinade Fresh Fruit and Muscle Marinade Cherry Limeade contain DMAA, vitamin C, vitamin E, selenium, chloride, potassium, sodium, creatine, and a blend of amino acids. It is promoted as a pre-workout energy powder.

(See's Reviews of Muscle Enhancers and Energy Drinks for tests of related products, and see Reviews of Vitamin E Supplements, Selenium Supplements and Potassium Supplements for tests of products that contain these ingredients.)

In addition, statements made on Purus Lab's website about its testosterone and nitric oxide booster supplement, D-Pol Powder, were found to be drug claims. D-Pol contains vitamin D3, vitamin B6, vitamin B9, vitamin B12, sodium and nitrate. It was promoted with statements such as "nitrate supplementation has been reported to lower blood pressure in humans."

Fat Smack XR Thermolipolytic, Muscle Marinade Fresh Fruit, Muscle Marinade Cherry Limeade, SLINshot, Condense, D-Pol and Recycle were also found to be misbranded because the labels contain inconsistencies and do not include certain information required by federal regulations.
