Dose Range Community/anecdotal only: ~5-25 mg per day, oral. No validated or approved human dose exists. Frequency Typically once daily (morning) in community reports; frequently cycled rather than taken continuously. Cycle Length No established protocol. Community users commonly run short blocks (about 4 weeks) with breaks, given the absence of any long-term human safety data and 9-Me-BC's MAO-A inhibition. Half-Life Not characterized in humans (no pharmacokinetic data). Dosage Calculator Calculate exact dosing for 9-Me-BC (9-Methyl-β-carboline). https://www.bodyhackguide.co/tools/dosage ## Dosing Protocols Beginner Community starting point (anecdotal - NOT a validated human dose): many users begin at ~5 mg once daily in the morning with food and hold there for 1-2 weeks to gauge tolerance. There is no human pharmacokinetic or safety data for 9-Me-BC; every figure here is extrapolated from online nootropic-community reports, not clinical evidence. Because 9-Me-BC inhibits MAO-A in vitro (IC50 ~1 uM [PMID:32285253]), treat it with MAOI-style caution: do not stack it with SSRIs/SNRIs, other MAOIs, sympathomimetic stimulants or serotonergic supplements, and be aware of the theoretical tyramine (blood-pressure) interaction with aged/fermented foods. Research use only. Standard Anecdotal mid-range: ~10-15 mg once daily in the morning, run in short blocks (commonly about 4 weeks) rather than continuously, since long-term safety is completely unstudied. Community users report stimulation, focus and motivation; if sleep is disrupted, dose earlier in the day. No human data support efficacy or safety at this dose - this reflects forum practice only. Keep MAO-A-inhibition precautions in force (no serotonergic-drug stacking; mind tyramine-rich foods). RUO. Advanced Some experienced community users report up to ~20-25 mg once daily, still cycled (e.g. a few weeks on, then off). Higher intakes increase the theoretical risk from MAO-A inhibition (hypertensive/tyramine reactions; serotonin toxicity if combined with serotonergic agents) without any evidence of added benefit. There is no validated rodent-to-human dose scaling, no established ceiling and no human toxicology for 9-Me-BC. This is the highest-uncertainty tier and is not a recommendation. RUO. ## Commonly Stacked With Do NOT stack with any serotonergic compounds. Can combine with non-serotonergic dopaminergics like Bromantane or Uridine with caution. One of the few compounds theorized to rebuild dopaminergic capacity rather than just utilize existing stores. ## Side Effects & Safety No human safety data exist for 9-Me-BC, so there is no verified side-effect profile - the following are theoretical or anecdotal only. Community users most often report stimulation-type effects: insomnia if dosed late, anxiety or overstimulation, and headache. Because 9-Me-BC is a potent in-vitro MAO-A inhibitor [PMID:32285253], MAOI-class risks are plausible in principle: hypertensive reaction with tyramine-rich (aged/fermented) foods, and serotonin toxicity if combined with serotonergic drugs. Beta-carbolines as a chemical class have also been studied for genotoxic/neurotoxic potential at high exposure, and the long-term effects of 9-Me-BC in humans are entirely unknown. RUO. Contraindications Precautionary (there is no human data to define true contraindications): avoid combining with SSRIs, SNRIs, MAOIs, other serotonergic drugs, or sympathomimetic stimulants due to 9-Me-BC's in-vitro MAO-A inhibition and the theoretical serotonin-toxicity / hypertensive (tyramine) risk. Not for use in pregnancy or breastfeeding, in anyone with significant cardiovascular or hepatic disease, or alongside prescription medications, given the complete absence of human safety testing. Research use only - not for human consumption. Check interactions with the Interaction Checker → (https://www.bodyhackguide.co/tools/interaction-checker) ## Additional Notes All dosing figures are extrapolated from online nootropic-community anecdote - there is no human pharmacokinetic, dose-finding or safety study for 9-Me-BC, and its half-life in humans is unknown. Because it inhibits MAO-A in vitro (IC50 ~1 uM [PMID:32285253]), standard MAOI precautions (avoid serotonergic drugs; be mindful of tyramine-rich foods) are prudent even though these interactions have not been formally documented for this specific compound.
