TikTok has begun returning no search results for certain peptide-related terms including semaglutide, BPC-157, and retratutide as of October 20, 2026, according to The Verge. While the censorship does not completely eliminate visibility of peptides on the platform, peptides that include unregulated and unapproved substances continue to be visible through other means. Advocates including RFK Jr. have promoted these peptides for various health claims ranging from weight loss to wound healing despite lack of scientific validation. The search restrictions appear designed to limit discovery of unregulated substances while not entirely preventing discussion of peptide-related health topics. The move reflects TikTok's effort to balance limiting promotion of unregulated health products against free expression concerns.
