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 half-life visualizer.

Cycling

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

Side effects & warnings

• 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.
