Is LL-37 FDA approved?

No. This site's US legal-status field is not approved, research use only. UK: not licensed. Australia: not approved, prohibited in sport (WADA). Canada: not approved. The 34-person topical ulcer pilot and the 148-person Phase 2b miss are the human record on that page, not an approval package. Sub-national detail is not in this dataset. This FAQ does not invent a US approval. Full record at /compounds/ll-37.
