Approximately 30% of patients treated for major depressive disorder develop treatment-resistant depression (TRD). The STAR*D study demonstrated remission rates decline progressively with each antidepressant failure (37%, 31%, 14%, and 13%, respectively). A single-day individualized dosing regimen of GH001 (synthetic mebufotenin for inhalation) produced rapid, large improvements in depressive...

Classical serotonergic psychedelics (e.g., LSD, psilocybin, DMT) alter perception and neuroplasticity primarily via 5-HT2A receptor activation and downstream Ca2+-dependent signaling cascades. Here we propose a speculative yet falsifiable pharmacological hypothesis that these drug-induced biochemical cascades might interface with quantum-mechanical processes in the brain. We focus on nuclear...

This article presents a mechanism of action hypothesis to explain the rapid antidepressant effects of esmethadone (REL-1017) and other uncompetitive N-methyl-D-aspartate receptor (NMDAR) antagonists and presents a corresponding mechanism of disease hypothesis for major depressive disorder (MDD). Esmethadone and other uncompetitive NMDAR antagonists may restore physiological neural plasticity in...

However, there are very few scientific studies that have specifically addressed this issue, and there is no agreed scientific consensus on what microdosing is....
