Where to buy Methylhexanamine (DMAA) for sale online


Methylhexanamine, also known as methylhexanamine, 1,3-dimethylamylamine, 1,3-DMAA, dimethylamylamine, and DMAA, was created and developed by Eli Lilly and Company. It was introduced as an inhaled nasal decongestant in 1948 and remained on the market until the 1980s when it was voluntarily withdrawn.
Since 2006, methylhexanamine has resurfaced under various names and has been widely sold as a stimulant or energy-boosting dietary supplement. Some marketing claims suggested it was akin to certain compounds found in geraniums. However, concerns about its safety have arisen due to a number of adverse events and, notably, at least five deaths linked to dietary supplements containing methylhexanamine. Consequently, it has been prohibited by numerous sports authorities and governmental agencies. Despite receiving multiple warning letters from the FDA, as of 2019, this stimulant continued to be available in sports and weight loss supplements.

In April 1944, Eli Lilly and Company introduced a compound known as methylhexanamine, marketed under the brand name Forthane, as an inhaled nasal decongestant. However, in 1983, Lilly made a voluntary decision to withdraw methylhexanamine from the market.[11]: 12 This compound falls into the category of aliphatic amines. During the early 20th century, the pharmaceutical industry exhibited a keen interest in compounds of this class for their potential as nasal decongestants. This interest led to the introduction of methylhexanamine and four other similar compounds for nasal decongestant use: tuaminoheptane, octin (isometheptene), oenethyl (2-methylaminoheptane), and propylhexedrine. Octin and oenethyl eventually received approval for use in maintaining adequate blood pressure levels in patients undergoing anesthesia.

Marketing as dietary supplement

In 2006, Patrick Arnold reintroduced methylhexanamine as a dietary supplement, a move prompted by the final ban on ephedrine in the United States in 2005. Arnold brought it back to the market under the trademarked name Geranamine, which his company, Proviant Technologies, owned. Numerous supplements geared towards fat loss and workout energy, known as thermogenic or general-purpose stimulants, began incorporating methylhexanamine as an ingredient, often in combination with substances like caffeine. This combination mirrored the popular ephedrine and caffeine pairing.
Some methylhexanamine-containing supplements may mention “geranium oil” or “geranium extract” as the source of methylhexanamine. However, it’s important to note that geranium oils naturally lack methylhexanamine, and the methylhexanamine in these supplements is synthetically added material. Several studies have explored the potential presence of DMAA (methylhexanamine) in certain types of geraniums, but as of now, robust evidence supporting DMAA’s presence in plants remains limited.
The synthesis of methylhexanamine involves a chemical process where 4-methylhexan-2-one reacts with hydroxylamine, leading to the conversion of 4-methylhexan-2-one into 4-methylhexan-2-one oxime. This oxime is then reduced through catalytic hydrogenation, ultimately resulting in the production of methylhexanamine, which can be further purified via distillation.


Methylhexanamine is an indirect sympathomimetic drug with various physiological effects, including the constriction of blood vessels impacting the heart, lungs, and reproductive organs. Additionally, it induces bronchodilation, inhibits intestinal peristalsis, and exhibits diuretic properties. Most research has focused on the drug’s pharmacological effects when administered through inhalation. Understanding its oral effects is largely derived from extrapolating data from similar compounds.[^97^]

According to a 2013 review, the anticipated pharmacological effects of oral intake include bronchodilation and nasal mucosa impact with a single oral dose ranging from 4 to 15 mg. Effects on the heart may occur with a single oral dose of about 50 to 75 mg, while blood pressure effects are expected with approximately 100 mg. Due to its prolonged half-life, repeated doses within 24 to 36 hours can lead to progressively stronger pharmacological effects (build-up).[^98^]

Detection in Body Fluids

Methylhexanamine can be quantified in blood, plasma, or urine through gas or liquid chromatography-mass spectrometry. This analytical method serves to confirm poisoning diagnoses in hospitalized patients or provide evidence in medicolegal death investigations. Blood or plasma concentrations of methylhexanamine typically fall within the range of 10 to 100 μg/L for recreational users, exceeding 100 μg/L for intoxicated individuals, and surpassing 300 μg/L in cases of acute overdosage.


Toxicity and Health Implications

The LD50 for methylhexanamine, when administered intravenously, is 39 mg/kg in mice and 72.5 mg/kg in rats.

The FDA has cautioned that methylhexanamine narrows blood vessels and arteries, potentially raising blood pressure and increasing the risk of cardiovascular events, ranging from breathlessness and chest tightness to heart attacks. Several adverse events and at least five deaths have been associated with dietary supplements containing methylhexanamine. Reports have also linked secondary open-angle glaucoma to methylhexanamine supplementation.

In 2012, a review conducted by a panel convened by the U.S. Department of Defense to assess the potential ban of methylhexanamine supplements on military bases concluded that while existing evidence did not definitively establish a causal link between DMAA-containing substances and adverse medical events, there was a consistent indication that DMAA could impact cardiovascular function, similar to other sympathomimetic stimulants. The panel emphasized the need for further rigorous studies on DMAA’s safety, especially concerning concurrent use of other substances, underlying medical conditions, and high-frequency use. While the overall risk of DMAA-related events might be low, its widespread use among service members, often combined with other substances, could lead to significant consequences for some. As a result, the panel recommended continuing the prohibition of sales of DMAA-containing products on bases.

Deaths and Injuries

In 2010, a 21-year-old man in New Zealand experienced a cerebral hemorrhage after consuming 556 mg of methylhexanamine, caffeine, and alcohol. In Hawaii, health authorities linked cases of liver failure and one death to OxyElite Pro, a dietary supplement used for weight loss and bodybuilding.

The death of Claire Squires, a runner who collapsed near the finish line of the April 2012 London Marathon, was associated with methylhexanamine. The coroner suggested that methylhexanamine was “probably an important factor” during the inquest. Despite having been diagnosed with an irregular heartbeat and advised against methylhexanamine consumption, it is believed that she inadvertently ingested the substance through an energy drink. Subsequently, the formulation of the drink was changed to exclude methylhexanamine.


Regulation and Bans

Methylhexanamine has faced stringent restrictions and bans in numerous countries and within various sports organizations due to significant safety concerns. Countries where its use is prohibited or heavily restricted include Australia, Brazil, Canada, Finland, New Zealand, Sweden, Switzerland, the United Kingdom, and the United States.
