output of biology.

What we do

Molecular design of mental states

We're building the closed-loop science + engineering stack for rational psychoactive effect design.

A molecular experience interface

Our molecular-experience interface links biology to human experience, transforming effects like clarity, presence, and motivation into quantitative design targets.

Research + development programs

Our clinical programs are a sequence of human demonstrations that psychoactive effects can be decomposed, recombined, and synthesized. Our primer + probe fixed-dose combinations iteratively test targeted psychoactive effect profiles that advance directly to human trials.

Program timeline

MSD-101
MSD-101: AESTHETICS trial, Phase 1b/2a.
MSD-102
MSD-102: ASSURANCE arm, Phase 1b/2a.
MSD-103
MSD-103: WARMTH arm, Phase 1b/2a.
MSD-104
MSD-104: Phase 1b/2a.
MSD-1XX
MSD-1XX: Phase 1.
MSD-2XX
MSD-2XX: Target discovery + validation.

The first controlled study of primer MSD-001 decomposed hallucinations and other effects from the broader hallucinogen profile.

The upcoming human study of the first primer + probe combination is designed to selectively upregulate aesthetic salience to treat anhedonia in major depressive disorder.

Additional parallel programs are designed to demonstrate de novo synthesis of novel psychoactive effects.

Discovery-stage programs optimize for single-molecule, multi-target action producing a broader range of psychoactive effects.
