What is DMAA?

DMAA (short for 1,3 dimethylamylamine) is a compound with many names. It is also known as 1,3 dimethylpentlamine, 1,3 dimeth, methylhexaneamine, Geranamine, and geranium oil or extract. DMAA is an effective stimulant and was a popular ingredient in supplements like pre-workouts & thermogenic fat burners.

Where Does DMAA Come From?

DMAA (1,3-dimethylamylamine) is a synthetic compound. However, some early marketers of dietary supplements containing DMAA have claimed it is derived from natural sources, such as the geranium plant (Pelargonium graveolens). Traditionally, this plant has been valuable in the perfume industry for its pleasant range of smells.

Nonetheless, scientific studies (Pieter, 2012) have largely refuted this claim, indicating that the DMAA found in dietary supplements is of synthetic origin. The initial introduction of DMAA was as a synthetic pharmaceutical for nasal decongestion.

DMAA Benefits

DMAA is an effective central nervous system stimulant and consequently was used as a pre-workout and a thermogenic supplement ingredient.

DMAA Benefits for Bodybuilding

DMAA has been popular among bodybuilders for several purported benefits:

  • Stimulant Effects: DMAA acts as a central nervous system stimulant, increasing alertness & giving a boost in energy, which can be beneficial for intense workouts.
  • Increased Focus: Users have reported enhanced concentration during workouts, which can help in maintaining effective training sessions.
  • Fat Loss: DMAA has thermogenic properties, meaning it can increase metabolism and promote fat burning, assisting in weight loss or cutting phases.
  • Enhanced Performance: Some users believe that DMAA can increase endurance and reduce perceived effort, allowing them to train harder and longer.
  • Vasoconstriction: Unlike other pre-workout ingredients which are vasodilators, DMAA causes vasoconstriction. While this might not be a direct 'benefit', it can lead to a feeling of increased intensity for some users.

DMAA Benefits for Fat Loss

DMAA has been touted for its potential benefits in promoting fat loss. Here are the reasons why it was sought after for this purpose:

  • Thermogenesis: DMAA can increase the body's metabolic rate, leading to an increase in energy expenditure. This thermogenic effect can aid in burning more calories &, subsequently, fat.
  • Appetite Suppression: Some users have reported that DMAA can reduce appetite, leading to decreased calorie intake. This can be beneficial for those looking to create a calorie deficit for weight loss.
  • Increased Energy: As a stimulant, DMAA boosts energy levels, which can be helpful for individuals to maintain or increase their exercise intensity & duration, leading to more calories burned.
  • Enhanced Fat Oxidation: There's some evidence to suggest that DMAA might increase the rate at which the body utilizes fat for energy, especially during exercise.

DMAA Negative Effects and Side Effects

DMAA (1,3-dimethylamylamine) has been associated with several negative effects and side effects. Some of these side effects include:

  • Cardiovascular Issues: DMAA can increase blood pressure and heart rate, which can lead to serious cardiovascular events such as heart attack, stroke, & arrhythmias.
  • CNS Stimulation: Overstimulation of the central nervous system can lead to symptoms like jitteriness, anxiety, & nervousness.
  • Sleep Disturbances: Due to its stimulant properties, DMAA can cause insomnia or poor quality sleep if taken later in the day.
  • Shortness of Breath: Some users have reported feeling short of breath or experiencing tightness in the chest after consuming DMAA.
  • Risk of Dependency: While not common, there's potential for dependency or abuse due to its stimulant nature.
  • Headaches and Dizziness: Some users have reported experiencing headaches or dizziness after taking DMAA.
  • Nausea & Upset Stomach: DMAA can cause gastrointestinal distress in some individuals.
  • Mood Changes: Irritability, mood swings, & even depression have been reported by some users.
  • Vasoconstriction: DMAA can lead to the narrowing of blood vessels, which can further contribute to the risk of cardiovascular issues.
  • Elevated Body Temperature: There's potential for DMAA to cause hyperthermia, especially when combined with vigorous exercise.

DMAA Legal Status

  • The first major ban on DMAA was carried out by the US military in mid-2012, but it was stated that such a ban was merely precautionary, and there was no evidence to suggest that DMAA caused harmful effects.
  • As of August 8th 2012, DMAA and DMAA-containing supplements in Australia were banned for import, supply & private use. This followed in the footsteps of other countries including New Zealand and Canada.
  • DMAA as of June 2012, was no longer being used as an ingredient by United States supplement manufacturers (after the issue of an FDA warning letter). Thus DMAA was withdrawn from the shelves of retailers and was mostly unavailable after 2012.
  • DMAA (1,3-dimethylamylamine) is classified as a prohibited substance in Australia. The Therapeutic Goods Administration (TGA) of Australia has listed DMAA as a Schedule 10 substance under the Poisons Standard. A Schedule 10 classification means that the substance is of such danger to health as to warrant prohibition of sale, supply, & use.
  • In the United States DMAA (1,3-dimethylamylamine) is considered illegal to be sold as a dietary supplement. The U.S. Food & Drug Administration (FDA) has warned that DMAA is not a dietary ingredient & thus, products containing DMAA are not allowed to be marketed as dietary supplements.
  • DMAA (1,3-dimethylamylamine) is banned for use in sports by the World Anti-Doping Agency (WADA). It is listed on WADA's Prohibited List, which means that athletes who test positive for DMAA in doping controls can face sanctions.

Recommended Doses and Ingredient Timing

Historically, when DMAA was more commonly found in dietary supplements, dosages ranged from 25 mg to 75 mg per serving, depending on the product and its intended use. Some pre-workout or fat-burning supplements might have recommended starting with half a serving to assess tolerance before moving to a full serving.

In terms of timing, many users took DMAA-containing products 20-30 minutes before exercise due to its stimulant effects. However, considering its potential to disrupt sleep, it was generally not recommended to consume DMAA in the evening or close to bedtime.

DMAA Supplements

DMAA was a common ingredient in certain pre-workout supplements & some thermogenic fat burners. Following is a sample list of supplements that previously contained the ingredient DMAA, all of which today have ceased including the ingredient DMAA in their brand formulations:

  • USPlabs Jack3d
  • USPlabs Oxy Elite Pro
  • MRI Black
  • Nutrex Hemorage Black
  • Nutrex Lipo-6 Black
  • Isotori PWR
  • Musclemeds Code Red
  • Muscle Warfare Napalm
  • Farenheit Lean Efx

  • Caffeine: Good old caffeine – we all know it and love it.
  • L-Theanine: Ever wondered why tea is calming? L-Theanine is the reason. Pair it with caffeine, and you've got a balanced energy boost without the jitters.
