DMHA Energy & Performance Historical pharmaceutical; no modern clinical trials # DMHA Dosage Guide: Protocols, Calculator & Safety Everything you need to know about DMHA dosing — protocols, safety, and where to buy. Dose Range 75-200 mg per dose (anecdotal pre-workout range; ~75,000-200,000 mcg). Historical pharmaceutical unit dose was 8-33 mg. No approved or clinically validated dose exists. Frequency Acute, single-session (pre-workout) use rather than a daily or continuous compound. Users typically leave rest days between doses to limit tolerance buildup and cardiovascular strain; there is no evidence base for any regular dosing schedule. Cycle Length No established or evidence-based cycle. As a sympathomimetic stimulant, prolonged daily use is discouraged; anecdotal practice is intermittent, training-day-only use with frequent breaks. No safety data support any long-term cycle. Half-Life Not formally characterized in humans. After ingestion, octodrine is rapidly metabolized to heptaminol, which becomes the predominant compound detected in blood and urine within hours \[PMID:39401652\]. Users commonly report perceptible stimulant effects lasting roughly 3-6 hours, but this is anecdotal rather than measured pharmacokinetics. [ Dosage Calculator Calculate exact dosing for DMHA. ](/tools/dosage) ## Dosing Protocols Beginner There is no established, approved, or clinically validated dose for DMHA. The figures below reflect what pre-workout users report anecdotally and are provided for research and harm-reduction context only - not as a recommendation to use it. Cautious users start low, around 75-100 mg taken once, roughly 20-30 minutes before training, on a day with no other strong stimulants on board. For perspective, older European pharmaceutical products used far smaller unit doses of just 8-33 mg \[PMID:29115866\]. Individual response varies widely; blood pressure and heart rate should be assessed before any repeat exposure, and anyone with a cardiovascular history should not use it at all. Standard Community 'standard' pre-workout dosing is commonly cited around 100-150 mg, often stacked with caffeine (typically 150-300 mg). Be clear about what that stack does: combining two sympathomimetics raises blood pressure and heart rate additively, increasing cardiovascular load. Commercial products that have actually been lab-tested contained octodrine in the range of 18-73 mg per serving \[PMID:33755516\] and about 72 mg in another analysis \[PMID:29115866\] - so a single 'scoop' may already deliver an intermediate dose before you add anything. This is acute, single-session use with off days between exposures, not a daily supplement. Advanced Some experienced users report 150-200+ mg, but this tier is documented, not endorsed. Independent laboratory analysis found supplement products containing up to 112 mg of octodrine per serving - more than three times the highest historical pharmaceutical dose \[PMID:29454882\]. Doses in this range sharply increase the risk of hypertension, tachycardia, chest tightness, and hyperthermia \[PMID:29461475\]. There is no clinical evidence supporting these amounts, and reviewers note these stimulant cocktails 'have never been tested in humans and their safety is unknown' \[PMID:33755516\]. Given DMHA's structural kinship with DMAA - a stimulant investigated in connection with hemorrhagic stroke and sudden death - high-dose use carries real, unquantified cardiovascular risk. ## Side Effects & Safety Reported and expected effects reflect its sympathomimetic activity: elevated blood pressure and heart rate, palpitations or tachycardia, chest tightness, shortness of breath (dyspnoea), overheating (hyperthermia), anxiety and jitteriness, headache, insomnia, and a post-dose crash \[PMID:29461475\]. Because DMHA is chemically and pharmacologically similar to DMAA - a stimulant investigated in connection with hemorrhagic stroke and sudden death - serious cardiovascular events are a plausible risk, especially at the high doses found in supplements or when stacked with other stimulants \[PMID:29115866\]\[PMID:33755516\]. Long-term safety in humans is entirely unstudied. Contraindications Avoid entirely if you have any cardiovascular condition (hypertension, arrhythmia, coronary disease), a history of stroke, are pregnant or breastfeeding, are under 18, or take MAO inhibitors, other stimulants, or blood-pressure-affecting medications. Do not combine with other sympathomimetics (high-dose caffeine, DMAA, ephedrine, synephrine, yohimbine) or use before high-heat or endurance exertion where hyperthermia risk is elevated. Competitive athletes must avoid it: octodrine and its metabolite heptaminol are prohibited in competition by WADA and have produced doping sanctions even when they entered the body through a contaminated supplement \[PMID:39401652\]. [Check interactions with the Interaction Checker →](/tools/interaction-checker) ## Additional Notes Treat any label dose with skepticism. Independent analyses repeatedly found the amount of octodrine in products differed from the label, ranged from 18 to 112 mg per serving, and was frequently combined with other prohibited stimulants (1,3-DMAA, 1,4-DMAA, 1,3-DMBA, oxilofrine, deterenol, higenamine) in undisclosed cocktails \[PMID:29115866\]\[PMID:33755516\]. Two distinct isomers are sold under the 'DMHA' name, and products marketed as 'natural' (sourced from Aconitum or Kigelia africana) were shown to contain synthetic material - no DMHA was detectable in those plants, and synthesis byproducts plus a racemic enantiomer ratio confirmed a laboratory origin \[PMID:29454882\]. ## Frequently Asked Questions What is the recommended DMHA dosage? The typical dose range for DMHA is 75-200 mg per dose (anecdotal pre-workout range; ~75,000-200,000 mcg). Historical pharmaceutical unit dose was 8-33 mg.
