Glossary
The Prohibited List is the World Anti-Doping Code International Standard naming the substances and methods prohibited in sport. It is revised annually and takes effect on January 1. It governs eligibility to compete and nothing else: it is not drug law, it does not decide whether a substance may be sold, prescribed or compounded, and it is issued by a body with no regulatory authority over medicines.
Its peptide sections are expressly non-exhaustive, and section S0 prohibits any pharmacological substance with no current approval by any governmental regulatory health authority for human therapeutic use. A substance the List does not name may therefore still be prohibited by description, which is why absence from the List is never evidence that a compound is permitted in sport.
The 2026 Prohibited List names twelve of the 40 molecules this index searched it for. The others are not named, which is not the same as permitted: section S0 covers any substance with no current approval for human therapeutic use.
