LL-37 research listings: prices and suppliers
Research materials and consumer products belong to different categories. A listing, laboratory report, or research-use label does not establish suitability for personal use.
We have no commercial relationship with suppliers on this page. Offers are sorted by price per mg; commission never changes the order.

- Prices exclude shipping. A matching name does not verify the contents of a lot.
- Lab reports are vendor-reported, not independently authenticated. “Lab confirmed” means the issuing laboratory confirmed the report is theirs.
- Some suppliers’ product pages include use or preparation wording. We list their prices for comparison only; we do not endorse that wording, and nothing on this site is guidance on preparing or using these materials.
