What 9-Me-BC is

9-Methyl-β-carboline, a research compound that acts as a MAO-B inhibitor and neuroprotective agent. Enhances dopamine function and may support cognitive health.

What 9-Me-BC is used for

• Cognitive enhancement
• Dopamine support
• Neuroprotection
• MAO-B inhibition
• Mood enhancement
• Potential Parkinson's support research

These are reported/community uses, not proven clinical outcomes. Most research peptides have limited human trial data behind such claims.

Typical reported dosing

Oral	5–30mg taken orally daily, typically in the morning

Presented as commonly-reported patterns for information only – not a dose recommendation. 9-Me-BC dosing is a decision for a qualified clinician.

Half-life & cycling

Half-life: Approximately 4–6 hours. Half-life drives dosing frequency and how quickly the compound clears – see it plotted on the 9-Me-BC half-life calculator.

Cycling

Typical cycles: 8–12 weeks on, 4 weeks off. Can be used continuously with breaks. Start with lower doses.

Side effects & warnings

Stop and get medical help if any of these happen. This is not the general "talk to a clinician before you start" line further down; these are the things that need attention on the day they appear, whatever you decided about 9-Me-BC.

an injection site that turns red, hot or hard, spreads, weeps, or comes with a fever – same-day medical care – research-grade material carries no sterility guarantee, so abscess and cellulitis are the documented consequence
swelling of the lips, tongue or throat, trouble breathing, or widespread hives after a dose – emergency care
a new or sharply worsening mood change, or any thought of harming yourself – urgent medical help; stop the compound

• Generally well-tolerated
• Possible mild stimulation
• Possible mild insomnia if taken late
• Limited long-term safety data

Research use only. MAO-B inhibitor – avoid foods high in tyramine when using. Start with lower doses (5–10mg). May cause mild stimulation. Take in morning to avoid sleep interference. Limited human research available. Not technically a peptide but often grouped with research peptides.

Not a prescription, a dose, or a sourcing guide. 9-Me-BC is a research compound; safety and efficacy in humans are not fully established, and research-grade material has no guarantee of purity, sterility, or stated strength. OptiPin is a tracking tool and does not recommend using research chemicals. Discuss any peptide with a qualified clinician.
