Work Out and Weight Supplements Contain Synthetic Amphetamine-Like Compound

On February 3, 2016, the FDA issued a warning letter to ATS Labs, LLC because labels for the company's work out and weight loss supplements CFI, Weapon-X Pre-Workout Extreme, and Lady Lean list a synthetic, amphetamine-like compound, 4-amino-2-methylpentane citrate (also called 1,3-dimethylbutylamine, AMP citrate, 4-methyl-2-pentanamine or DMBA) as an ingredient.

DMBA is an analogue of the pharmaceutical stimulant, 1,3-dimethylamylamine (DMAA), which is banned by the FDA. DMBA may also be listed on labels as 1,3-Dimethylbutylamine, 2-amino-4-methylpentane, AMP citrate, AMP, or 4-methyl-2-pentanamine .

In addition, an FDA facility inspection found these and other products, including Support, Liver Food, Test PSI, Lipo Blast, Dilate, Winalean and Pro Flex to be adulterated, because they were prepared, packed, or held under conditions that violate Current Good Manufacturing Practices for dietary supplements.

These violations include failure to establish specifications providing sufficient assurance that products received for packaging or labeling as a dietary supplements are adequately identified and consistent with purchase orders, and failure to establish and follow written procedures for the responsibilities of quality control operations, as required by federal regulations.
