What is DMHA (Octodrine)?

DMHA, also known as Octodrine or 2-amino-6-methylheptane, is a synthetic stimulant that was once widely used in sports supplements. Its main appeal came from its energising effects, enhanced mental focus, and appetite-suppressing properties. Closely related to DMAA and tuaminoheptane, DMHA briefly became the go-to performance enhancer in pre-workouts and fat burners before being banned in multiple countries.

The History of DMHA

DMHA was first developed in the 1940s as a pharmaceutical compound used in nasal decongestants and bronchodilators. After decades of dormancy, it reappeared in sports supplements around 2015 when ingredients like DMAA and AMP Citrate were being restricted by regulators. DMHA’s similar stimulant profile made it a popular substitute—until growing safety concerns prompted its own regulatory bans, including in Australia.

DMHA in Australia: Legal Status

On October 1st, 2017, DMHA was added to the Schedule 10 poison list under Australian law, meaning it is banned from sale, supply, and importation without a special permit. This ban applies to all forms of DMHA, and no reputable Australian supplement companies currently use or offer it in any products.

Where Does DMHA Come From?

There are two structural variations of DMHA:

• 2-amino-6-methylheptane: This is the synthetic version, most commonly used in supplements.
• 2-amino-5-methylheptane: A naturally occurring version found in Juglans Regia (walnut bark), though rarely used due to extraction costs and legal compliance challenges.

Early speculation that DMHA could be derived from Aconitum kusnezoffii has been debunked due to the plant’s extreme toxicity.

• 🌶️ Help during cutting phases by controlling hunger

DMHA Side Effects and Safety

• ⚠️ Elevated heart rate and blood pressure
• 😧 Nervousness, jitteriness, or anxiety
• 📊 Sleep disturbances
• 😬 Shortness of breath
• ⚠️ Risk of overstimulation if combined with other stimulants

DMHA Dosing and Timing

While no official human dosage guidelines exist, users historically consumed between 100mg–150mg 30–60 minutes before training. However, given its banned status and potential risks, this compound is no longer advised for supplementation.

DMHA in Supplements

DMHA was commonly used in aggressive pre-workouts and fat burners between 2015 and 2017. Since its inclusion in Schedule 10, it has disappeared from reputable brands. No respected Australian manufacturers would even consider using DMHA, and products containing it are considered non-compliant with TGA regulations.

Stacking DMHA

• 🏋️‍♂️ Non-stimulant pre-workouts
• 🌿 BCAAs
• 🚴 Creatine
• 🧃 Protein powders

It was never recommended to stack it with other strong stimulants due to the risk of overstimulation and adverse effects.

DMHA Alternatives

• 🔁 Teacrine (Theacrine)
• 🍊 Synephrine (Citrus aurantium)
• 💥 Higenamine HCL
• ☕ Caffeine (Anhydrous or Natural)
• 🌿 Guarana Extract
• 🥬 Green Tea Extract (EGCG + Caffeine)
• 🥤 Yerba Mate

Conclusion

DMHA (Octodrine) once filled the gap left by DMAA, delivering powerful stimulant effects that appealed to athletes and bodybuilders. However, due to safety and legal concerns, it was banned in Australia and is no longer found in reputable products. Fortunately, a range of effective and compliant alternatives is available to support energy and fat loss goals.

For safety, effectiveness, and compliance, always choose supplements from trusted Australian retailers like Mr Supplement. 💼
