What this means
- 01
No product containing LL-37 is approved by TGA for any use in Australia, so nothing on the market is authorized for people.
- 02
"Research use only" is a vendor label, not a legal category that permits human use. It does not exempt a product from medicines law.
- 03
Importing, supplying or promoting it for human use can fall under medicines legislation in Australia. This page is general information, not legal advice.
What LL-37 is
The main human cathelicidin antimicrobial peptide, central to innate immunity and wound healing, with a complex double-edged role in disease.
LL-37 is the active form of the only human cathelicidin, a key part of innate immune defense. It kills microbes directly, supports wound healing, and shapes immune responses.
Mechanism: Disrupts microbial membranes and modulates immune cell activity, wound repair, and inflammation.
Regulatory history: Not FDA-approved; research peptide
How TGA treats this kind of product
Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.
The classification above is the The Longevity Archive reading of Therapeutic Goods Administration listings for LL-37 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
