Compare Supplements

No legitimate or recommended dose — DMHA is an unapproved, unsafe ingredient that does not qualify as a dietary supplement, and it is banned in sport. We do NOT provide a dosing protocol. For reference only: octodrine was historically sold in Europe within multi-ingredient medications at 8–33 mg, but supplement products have contained 72 mg or more per serving — over twice that historical maximum, and stacked with other untested stimulants. That is not a recommendation.

Any time

None — unapproved, unsafe stimulant ingredient; not a lawful dietary supplement

• Anyone with cardiovascular disease, hypertension, or arrhythmia — DMHA is a pressor sympathomimetic and a DMAA analog with presumed cardiovascular risk
• Not an approved medicine and not a lawful dietary supplement — FDA treats it as an unapproved, unsafe ingredient; do not self-source
• Competitive athletes — octodrine and its metabolite heptaminol are WADA-prohibited and have triggered anti-doping violations, including from contaminated products

• Other stimulants (caffeine, sympathomimetics, decongestants)
• MAO inhibitors
• Stimulant or pressor blood-pressure-raising agents / antihypertensives
