What is geranamine?

DMAA (also known as geranamine, methylhexanamine, dimethylamylamine, 1,3-dimethylamylamine) is a natural CNS stimulant that was first synthesized and patented in 1944 by pharmaceutical company Eli Lilly. The substance was originally patented as a nasal decongestant. Geranamine is increasingly used as main ingredient in energizer, fitness supplements and weight-loss products.

Geranamine Effects

The stimulant effects of geranamine on the central nervous system (CNS) are said to be less than amphetamine and ephedra. Effects are dose-dependent and include euphoria, elevated mood, intense energy, adrenaline rush, mental clarity and increased confidence.


IUPAC Name: 4-methylhexan-2-amine
CAS Number: 105-41-9
Formula: C7H17N
Molar Mass: 115.22 g/mol

The chemical structure shows resemblances to that of amphetamines and ephedrine.

The name ‘Geranamine’ is actually a trademark name, registered by Proviant Technologies. DMAA is a naturally-occurring constituute of the geranium plant (Pelargonium graveolens). However, this is less than 1%, and most DMAA on the market is produced synthetically.

Legal status

Geranamine is currently legal in most countries. Because the compound is a natural constituent of geraniums and is unscheduled it can be sold as a dietary supplement under current FDA laws.

In 2010, the World Anti-Doping Agency (WADA) added geranamine to the list of banned performance enhancing substances.

    So with the WADA adding this substance into the list of banned performance enhancing substances is it illegal to take while in the armed forces? Could i get a drug test back saying i was taking and illegal substance when all i was doing was taking a pre-workout formula? I know that the Navy banned JACK3D because it makes people test positive for drugs, im not sure about any other branch, but they took it out of the NEX along with a few other things for the similar reason.

    DMAA is a great stimulant for working out with little “crash” when coming off. it elevates the mind, gives a feeling of well being, open the sinus`s, soon the U.S. government will be adding this to the banned list. after all, the government does`nt need anything competing with thier cocain sales. controlling drugs is not controlling a substanse, its controlling peoples feelings. i love my country but i fear my government.

    Can DMAA be addicting or harmful? Can a person become dependent on it or be become sketchy and twitchy? Im looking at “HI-Octane”

      Usually these PRE workout seeplumpnts have almost no calories since they are just a bunch of stimulants, nitric oxide, creatine, and amino acids. So it wouldn’t cancel out the calories you’re burning during your workout.Protein powders and other POST workout seeplumpnts (not mentioned on this article), do contain calories so they do kind of cancel out the calories your burn during your workout (ignoring the after burn from your exercises). That being said, here’s some general advice.It sounds like your goal is to lose weight. The rule of thumb for getting fit for you is:Eat less to lose weightExercise to improve strength, endurance, and cardiovascular healthSo you should not look into trying to burn calories with exercise but rather you should exercise to improve strength, endurance, and cardiovascular health. Protein powders or any other post workout seeplumpnts are there to help you recover faster from your intense exercise so that you can exercise again in a day or two.Thanks for visiting and great question! 5 months ago

    Great ******* website!

    The most honest information I can find on this wonder drug. I dislike caffeine, yet love geranium. Thanks for compiling all this info. VERY VERY much appreciated =)

      Just curious, what does your feirnd take as a pre-workout supplement?Sounds like your feirnd is overreacting to bro-science. All stimulants (including caffeine) are heart attacks waiting to happen IF you take too high of a dose, your body will freak out and yeah get a heart attack. Everybody reacts differently to certain stim. If he’s sensitive to a particular stim, take less of it (more bang for your $$ anyway) or don’t take any, but don’t tell others to not take the stims.I’m personally am not a big fan of long term use of DMAA (main active ingredient in Jack3d and many other pre-workout supplements), mainly because you build up tolerance quick and there hasn’t been enough scientific studies on long term use. But for short term use where you implement a cycle ON and a cycle OFF, I see little harm. The way I cycle stims are: 2 weeks on non-DMAA (Choline based), 1 week on DMAA, 3 weeks no stims.And also, pre-workout supplements are designed to get into your system, help you lift some heavy stuff, and leave your system fast. It shouldn’t linger. If you want endurance during your lifts, supplement with some BCAAs at 30-60 minute intervals peri-workout (depending on your work load). And you can look into beta-alanine too (even though beta-alanine only helps a little at the high rep range). 1 month ago

        From wikipedia: “A study of 25 healthy men taking a methylhexanamine-containing preworkout sports supplement found methylhexanamine does not change resting heart rate, blood pressure, or affect liver and kidney function when used at recommended dosage levels.[21] According to an additional four studies, DMAA did not seem to cause any negative effects to the blood, blood pressure or heart rate when taken by test subjects for a short period”


        not denying what he said, individual results always vary. but indeed be careful

    Thanks for the tip! I checked it out on blodbuiyding.com and it looks pretty good. I guess at $2.13 per serving it has to be good. Maybe I’ll try it one of these days whenever I feel like Jack3d is no longer doing it’s job and whenever I feel like ponying up the money. 5 months ago

    The physique then goes into starvation mode and you start losing muscle as well as fat.
    Because of this, they feel like their stomachs
    do not have the capacity to expand like just before, thus impeding them from eating more.
    So whenever you use them do follow the instructions
