BTYBD is a harm reduction reference tool built on peer-reviewed clinical research. It provides factual, evidence-based information about psychoactive substances to support safer decision-making. This app does not promote, encourage, or facilitate drug use. It exists because people who choose to use substances deserve access to accurate safety information — not misinformation.

Each profile includes pharmacology, duration, risk factors, contraindications, and citations from published research. 236+ Clinical Studies A searchable index of peer-reviewed studies from institutions including Johns Hopkins, Imperial College London, NYU, and MAPS. Filter by compound, year, or research area. Molecule Studio Explore 3D molecular structures with interactive rotation, zoom, and element-colored atoms. Search over 110 million molecules from PubChem. Substance Interaction Matrix Check interactions between compound pairs with a color-coded safety matrix. Understand which combinations carry elevated risk, based on published pharmacological data. Harm Reduction Guides Practical safety guidance covering preparation, set and setting, dosage awareness, and what to do if something goes wrong. Grounded in decades of harm reduction practice.
