DMHA (Juglans Regia Extract / 2-Aminoisoheptane): Stimulant Banned in Some Sports — FDA Regulatory Status Uncertain
⚡ 60-Second Summary
DMHA (2-amino-6-methylheptane, also labeled as 2-aminoisoheptane, octodrine, or Juglans regia extract) is a synthetic sympathomimetic amine that appeared in pre-workout supplements around 2016, widely marketed as DMAA's legal successor. It has a similar amphetamine-like pharmacological profile: stimulates norepinephrine and dopamine release, producing vasoconstrictive and CNS-stimulating effects.
DMHA is not FDA-approved as a dietary supplement ingredient — the FDA issued warning letters to manufacturers in 2019 stating it is an illegal ingredient in dietary supplements. Like DMAA, serious adverse events including cardiovascular emergencies have been reported. It has not undergone safety assessment in controlled human clinical trials.
The repeated cycle of DMAA → DMHA → newer analogs reflects a cat-and-mouse pattern in the sports nutrition industry: when one amphetamine analog is regulated, another is marketed as its 'natural' or 'legal' alternative. Each carries similar safety risks with even less established safety data than its predecessor.
What is DMHA (Juglans Regia Extract / 2-Aminoisoheptane)?
'Juglans regia' (walnut) extract is the botanical name used to market DMHA, suggesting it's a natural extract. DMHA may exist in walnut husks in trace amounts, but commercial 'Juglans regia extract' in supplements is typically synthetic DMHA — not a true plant extract.
FDA warning letters were sent to multiple manufacturers in 2019; enforcement continues.
Evidence-based benefits
Pre-workout Stimulation (No Valid Clinical Evidence)
DMHA produces stimulant effects via norepinephrine/dopamine stimulation. No peer-reviewed human clinical trials establish safety or efficacy.
Adverse Event Reports
Multiple adverse events reported to the FDA related to DMHA-containing supplements, including cardiovascular events.
Supplement forms compared
| Form | Typical dose / Bioavailability | Best for | Notes |
|---|---|---|---|
| Form | Dose | Notes | Status |
| DMHA (any form) | DO NOT USE | FDA warning letters issued; not legal in dietary supplements | Illegal in supplements per FDA guidance |
| 'Juglans Regia Extract' in pre-workout | DO NOT USE | DMHA marketed under botanical name | FDA considers this adulteration of dietary supplements |
How much should you take?
- DO NOT USE — DMHA is not a legal dietary supplement ingredient per FDA guidance
- Report adverse events to FDA MedWatch
- Check supplement labels for: 2-aminoisoheptane, octodrine, Juglans regia extract, 2-amino-6-methylheptane — all refer to DMHA
- For pre-workout use: choose from legal, evidence-backed alternatives (caffeine, citrulline, beta-alanine, creatine)
DMHA-containing supplements are illegal as dietary supplements per FDA guidance. Like DMAA, the risk profile is unacceptable and the compound has no legitimate clinical application in dietary supplements.
Safety and side effects
Common side effects
- Cardiovascular stimulation: tachycardia, hypertension, vasoconstriction
- Adverse events similar to DMAA class stimulants
- No adequate safety characterization in humans
- Possible positive drug testing in sports
Serious risks
DO NOT USE. DMHA has the same risk category as DMAA — amphetamine-analog stimulant without human safety data or legal supplement status. WADA prohibits DMHA under stimulant class.
Drug and nutrient interactions
- Same as DMAA class — dangerous interactions with MAO inhibitors, other stimulants, cardiovascular medications

Frequently asked questions
Is DMHA safer than DMAA?
There is no basis to claim DMHA is safer than DMAA. It is a different amphetamine analog with similar mechanistic properties, no human clinical safety trials, FDA warning letters for supplement use, and adverse event reports. The fact that it was marketed as DMAA's 'safe alternative' reflects marketing strategy, not science.
What supplements might contain DMHA?
Pre-workout supplements from smaller manufacturers, particularly those marketed as 'hardcore' or 'extreme' products, may contain DMHA. Common label terms: Juglans regia extract, 2-aminoisoheptane, octodrine, 2-amino-6-methylheptane, DMHA. Many products that once contained DMAA reformulated with DMHA when DMAA enforcement increased.
Is DMHA detectable in drug tests?
DMHA may trigger positive results on some anti-doping tests as a stimulant. WADA has included it in the Prohibited List under stimulants. Military drug testing may detect it. Standard employment drug screens don't typically test for it, but specialized sports testing programs may.
What are legal alternatives for the energy DMHA products claim to provide?
Evidence-based, legal pre-workout stimulants: caffeine (200–400 mg), theacrine (100–200 mg), and Dynamine (50–100 mg). For performance beyond stimulants: beta-alanine for muscular endurance, citrulline malate for blood flow and power, creatine for strength and anaerobic performance. These have legitimate evidence bases and acceptable safety profiles.
