Methylhexanamine (also known as methylhexamine, 1,3-dimethylamylamine, 1,3-DMAA, dimethylamylamine, and DMAA; trade names Forthane and Geranamine) is an indirect sympathomimetic drug.
'''Methylhexanamine''' (also known as '''1,3-dimethylamylamine''', '''1,3-DMAA''', and '''2-amino-4-methylhexane''') is a lesser-known novel [[psychoactive class::stimulant]] substance of the [[chemical class::amine]] class. It has structural similarities to [[Amphetamine|amphetamine]] and is most notably used in dietary supplements related to resistance training. It is thought to produce its effects by increasing levels of the [[neurotransmitters]] [[epinephrine]], [[norepinephrine]], and to a lesser extent, [[dopamine]] in the brain.

{{In April 1944, Eli Lilly and Company introduced methylhexanamine under the brand name Forthane as an inhaled nasal decongestant; Lilly voluntarily withdrew methylhexanamine from the market in 1983. The compound is an aliphatic amine; the pharmaceutical industry had a strong interest in compounds in this class as nasal decongestants in the early 20th century, which led to methylhexanamine and four other similar compounds being brought to market for that use: tuaminoheptane, octin, oenethyl (2-methylaminoheptane), and propylhexedrine; octin and oenethyl were eventually approved for use in keeping blood pressure sufficiently high for patients under anesthesia.
Methylhexanamine was developed by Eli Lilly & Co. and marketed starting in 1948 as an inhaled nasal decongestant. The company voluntarily withdrew it by the 1970s.<ref>https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/1157413</ref>
For a molecule to be legally used in a dietary supplement in the United States, it must be naturally occurring and have a documented history of use prior to 1994.
In 1996, a study found methylhexanamine to be contained in trace amounts in geranium oil.<ref>Ping, Z., Jun, Q., & Qing, L. (1996). A study on the chemical constituents of geranium oil. Journal of Guizhou Institute of Technology, 25(1), 82-5.</ref>
These findings were subsequently not reproduced in multiple peer-reviewed publications.<ref>https://scribd.com/document/82744576/DMAA-Health-Canada-2011</ref>


Patrick Arnold reintroduced methylhexanamine in 2006 as a dietary supplement, after the final ban of ephedrine in the United States in 2005. Arnold introduced it under the trademarked name Geranamine, a name held by his company, Proviant Technologies. A large number of supplements focusing on fat loss and workout energy (thermogenic or general-purpose stimulants) used the ingredient in concert with other substances such as caffeine, a combination similar to the combination of ephedrine and caffeine.}}
Starting in 2006, methylhexanamine was used in several marketed sport supplements, most famously ''Jack3d'' by ''USPlabs''.
In April 2013, the FDA warned about methylhexanamine after 86 reports of heart problems, nervous system disorders, or death, and motioned manufacturers to stop using the substance.<ref>https://www.fda.gov/consumers/consumer-updates/stimulant-potentially-dangerous-health-fda-warns?source=govdelivery</ref>
The US Department of Defense published an investigation into methylhexanamine following the death of four soldiers which were linked with the substance in recreational doses.<ref>Lammie, C.

Methylhexanamine (also known as 1,3-dimethylamylamine, 1,3-DMAA, and 2-amino-4-methylhexane) is a lesser-known novel stimulant substance of the amine class. It has structural similarities to amphetamine and is most notably used in dietary supplements related to resistance training. It is thought to produce its effects by increasing levels of the neurotransmitters epinephrine, norepinephrine, and to a lesser extent, dopamine in the brain.

History and culture

Methylhexanamine was developed by Eli Lilly & Co. and marketed starting in 1948 as an inhaled nasal decongestant. The company voluntarily withdrew it by the 1970s.[1] For a molecule to be legally used in a dietary supplement in the United States, it must be naturally occurring and have a documented history of use prior to 1994. In 1996, a study found methylhexanamine to be contained in trace amounts in geranium oil.[2] These findings were subsequently not reproduced in multiple peer-reviewed publications.[3]

Starting in 2006, methylhexanamine was used in several marketed sport supplements, most famously Jack3d by USPlabs. In April 2013, the FDA warned about methylhexanamine after 86 reports of heart problems, nervous system disorders, or death, and motioned manufacturers to stop using the substance.[4] The US Department of Defense published an investigation into methylhexanamine following the death of four soldiers which were linked with the substance in recreational doses.[5]

Chemistry

Methylhexanamine is synthesized by reacting 4-methylhexan-2-one with hydroxylamine, which converts the 4-methylhexan-2-one to 4-methylhexan-2-one oxime, which is reduced with hydrogen by means of a catalyst; the resulting methylhexanamine can be purified by distillation.

Pharmacology

This pharmacology section is incomplete.

You can help by adding to it.

Subjective effects

This subjective effects section is a stub.

As such, it is still in progress and may contain incomplete or wrong information.

You can help by expanding or correcting it.

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.

It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.

Toxicity and harm potential

This toxicity and harm potential section is a stub.

As a result, it may contain incomplete or even dangerously wrong information! You can help by expanding upon or correcting it.
Note: Always conduct independent research and use harm reduction practices if using this substance.

It is strongly recommended that one use harm reduction practices when using this substance. Health authorities in Hawaii linked cases of liver failure and one death to OxyElite Pro, a weight loss and bodybuilding dietary supplement containing methylhexanamine.

Lethal dosage

The LD50 for methylhexanamine is 39 mg/kg in mice and 72.5 mg/kg in rats, when administered intravenously. In 2010, a 21-year-old male in New Zealand presented with a cerebral hemorrhage after ingesting 556 mg of methylhexanamine, caffeine, and alcohol.

Tolerance and addiction potential

Dangerous interactions

This dangerous interactions section is a stub.

As such, it may contain incomplete or invalid information. You can help by expanding upon or correcting it.

Warning: Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).

Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.

As of 2013, Methylhexanamine has been banned for legal sale in Canada, Sweden, Brazil, Australia, the United Kingdom, New Zealand, and the United States, and may be regulated to one degree or another in other countries. Possession of the drug itself is not criminal in most jurisdictions.
