Schedule I

Definition

Schedule I is the most restrictive category in the DEA Controlled Substances Act classification system. Schedule I substances are defined as having no currently accepted medical use in treatment in the United States, insufficient safety data for use under medical supervision, and high potential for abuse. Examples include heroin, MDMA, psilocybin (in most jurisdictions), and LSD. Research use of Schedule I substances requires a special DEA Schedule I researcher registration, DEA-approved secure storage, detailed record-keeping, and reporting, with the specific quantities and purposes regulated under the registration.

Research Context

Schedule I classification is relevant to peptide research context because some researchers compare research peptide regulatory status to more restrictive controlled substance categories. The research peptides available from Spartan Peptides (BPC-157, TB-500, GHK-Cu, Epithalon, NAD+, and others) are not Schedule I or II substances under current federal law. Understanding Schedule I requirements helps researchers appreciate the significantly different regulatory environment that applies to actually scheduled research chemicals versus unscheduled research peptide compounds.
