Searches on TikTok for peptides such as semaglutide, BPC-157, TB-500 and retatrutide now return a "no results found" page, The Verge reports. Videos have not been removed, a general search for "peptides" still works, and slight spelling variations get around the block. TikTok's U.S. owner did not immediately respond to The Verge.

Peptides include approved drugs like insulin and GLP-1s, but also unapproved substances that influencers promote, sometimes pointing followers to compounding pharmacies, for uses from weight loss to wound healing with little clinical data, The Verge says. Influencer Jeff Tang flagged the change and blamed Eli Lilly in a video.
