Synthetic Stimulant DMBA Found in 12 Supplements

Synthetic Stimulant DMBA Found in 12 Supplements

October 8, 2014 — Researchers have discovered a powerful synthetic stimulant known as 1,3-dimethylbutylamine (DMBA) in twelve dietary supplements marketed for weight-loss and bodybuilding.

DMBA is a chemical analogue to DMAA, which was recently banned by the U.S. Food and Drug Administration (FDA). Experts warn that side effects of DMAA and DMBA may be very similar.

DMAA can elevate blood pressure and heart rate, which could potentially cause heart problems, shortness of breath, chest tightness, heart attack, or even death.

The journal Drug Testing and Analysis published the study by Dr. Pieter A. Cohen, assistant professor at Harvard Medical School who is leading a campaign against illegal ingredients in dietary supplements.

Dr. Cohen discovered another synthetic stimulant in Craze, manufactured by Driven Sports, which was re-formulated with DMBA and sold under the brand-name Frenzy in Europe. The FDA issued a warning letter to Driven Sports in April.

Supplements That Contain DMBA

  • Frenzy (Driven Sports, Inc.)
  • Contraband (Iron Forged Nutrition)
  • Redline White Heat and MD2 Meltdown (Vital Pharmaceuticals Inc. or VPX)
  • Evol and Decimate Amplified (Genomyx LLC)
  • Oxyfit Xtreme and Synetherm (
  • AMPitropin and AMPilean (Lecheek Nutrition)
  • OxyphenXR AMP’D (Beta Labs Ltd.)

Other Names for DMBA

  • 4-amino-2-methylpentane citrate
  • AMP citrate
  • 1,3-dimethylbutylamine citrate
  • 4-amino-2-pentanamine, Pentergy
  • 4-AMP

Researchers found that the label on two supplements (Frenzy and OxyPhen XR AMP’D) implied that DMBA was an “all-natural” extract of Pouchong tea leaves. However, Dr. Cohen found that it would be physically impossible to extract enough DMBA from tea leaves to make even the lowest doses of DMBA he found in supplements.
