Schedule II & RFK ·
Most peptides are not federally scheduled under the Controlled Substances Act. Federal scheduling primarily covers opioids, stimulants, hallucinogens, and certain depressants. However, several substances sometimes categorized as 'peptide' or 'peptide-adjacent' sit in the controlled-substance space, and a few states have scheduled additional substances at the state level. Examples include certain growth hormone analogs. The RFK Jr. HHS's 2025–2026 review has examined whether existing state-level schedules are scientifically justified and whether any federal scheduling adjustments should be recommended to DEA. DEA retains the final scheduling authority at the federal level.
