5-MeO-DMT Neurobiology & Depression Remission Workbench

Receptor & Dose Kinetics

5-MeO-DMT Vapor Dose 12 mg (Effective)

Receptor Affinity Profile 5-HT1A Dominant

5-HT1A vs 5-HT2A Selectivity Ratio Ki ratio ~ 1:300

5-MeO has 300-1000x higher 5-HT1A affinity than classical psychedelics, inducing rapid Gi/o inhibitory hyperpolarization in dorsal raphe & cortical interneurons.

TrkB / BDNF Activation Force 88%

Neurobiological Remission Pipeline

1. Depressive Hyper-Rigid DMN Trap

In major depressive disorder, the Default Mode Network (mPFC-PCC axis) exhibits pathological hyper-synchrony, trapping the brain in persistent negative self-referential rumination, while chronic stress leads to loss of excitatory synapses in cortical pyramidal neurons.

5-MeO Specificity: Unlike psilocybin (5-HT2A partial agonist), 5-MeO-DMT binds 5-HT1A with sub-nanomolar affinity, instantly suppressing dorsal raphe pacemaker firing and collapsing localized cortical alpha-band power.
