TikTok blocks searches for BPC-157, other peptide names

TikTok has started returning a “no results found” page when users search for the names of several popular peptides, including BPC-157, TB-500, retatrutide and semaglutide. The Verge reported the change on Oct 20, 2026, a day after users on X began flagging it. The blocks are narrow so far. They cover search terms, not the videos themselves, and The Verge found they were easy to get around.

What has been confirmed

The Verge’s senior news editor Richard Lawler checked the search results himself. Searches for semaglutide, BPC-157, retatrutide “and others” led to the empty results page, and the report’s summary also names TB-500. Three points in that report limit how far the change goes:

• General searches still work. A search for the word “peptides” still pulled up plenty of short videos.
• Small misspellings get through. Slight variations of BPC-157 and TB-500 still surfaced published videos, and TikTok’s own search suggestions offered working variants as he typed.
• No sign of removals. The Verge said there was no sign that actual videos had been removed.

TikTok’s US owner did not respond right away when The Verge asked for comment. eMarketer, writing on Oct 22, summarized the same findings for BPC-157 and retatrutide and noted that it is unclear when the restrictions began.

According to eMarketer, TikTok told Endpoints News that peptide discussions are permitted, but that the platform prohibits marketing high-risk products and may restrict searches for unapproved or potentially unsafe products. We searched for the Endpoints report and could not find it, so that statement is attributed here to eMarketer’s account of it.

The statement lines up with TikTok’s written rules. Its community guideline on regulated goods, effective Sept 24, 2026, says the platform does not allow trading, marketing, or providing access to regulated, prohibited, or high-risk goods and services.

Myth check: has TikTok banned all peptide content?

Several widely shared posts on X described a total ban. The earliest we found came from Jeff Tang, the influencer The Verge credits with first flagging the change. His post, timed late on Oct 19 Eastern time, said TikTok had “fully banned all content about peptides.” Other accounts repeated that framing over the next two days.

The documented evidence does not support it. What has been shown is a block on certain search terms. Peptide videos were still visible through general searches and near-miss spellings, and The Verge saw no sign of mass removals.

Tang’s post also said a search for melanotan returned no results. The Verge did not name melanotan, so we treat that as a user report we have not confirmed. Some creators have also posted that their accounts or channels were removed. We have not verified any of those claims, and TikTok has not commented on individual accounts.

Why platforms are under pressure

Peptides have become a large topic on social video. Researchers from the University of Queensland, the University of Toronto and the University of California, San Francisco wrote in a Viewpoint article in JAMA in June that peptide-related content had drawn more than 230 million views on TikTok and more than 130,000 Instagram posts as of May 2026. (eMarketer described this as a study of hashtags; the authors’ university release describes it as peptide-related content.)

Several of the blocked names are drugs that are not approved. Retatrutide is an investigational Eli Lilly drug still in clinical trials. BPC-157 and TB-500 have no FDA approval for any use. The FDA has repeatedly sent warning letters to online sellers that label such products “research use only,” including five letters dated Aug 24, 2026. eMarketer also noted that Lilly has taken legal action against some sellers.

At the same time, federal policy may shift. The FDA’s Interim Access Policy for Compounding Using Certain Peptides has been under review at the White House Office of Information and Regulatory Affairs since Oct 14, 2026, according to OIRA’s review dashboard. Its text has not been published, and it is not final.

What is not known

• Which terms are blocked. No full list has been published. Reports so far name BPC-157, TB-500, retatrutide and semaglutide; melanotan comes only from user posts.
• Exactly when it started, and whether the blocks apply outside the US.
• Whether TikTok will go further, for example by removing videos or accounts. No mass removals have been documented.
• What prompted the change. Tang blamed Eli Lilly in a later video. Neither TikTok nor Lilly has said so, and we have seen no evidence for it.

We will update this story if TikTok publishes a statement or the scope of the blocks changes.
