Also known as: CAP-18, cathelicidin
LL-37 is a cathelicidin-derived peptide of 37 amino acids, sometimes listed under aliases like CAP-18 or cathelicidin. Vendors sell it as a research-use-only chemical, usually a lyophilized powder in single vials. As a longer chain it tends to carry a higher list price per vial than the small peptides, which makes cost per mg the number that actually matters when you compare vendors.
LL-37 vials are commonly sold in smaller milligram amounts than the popular repair peptides, so two listings at the same sticker price can hold very different quantities. The table above normalizes each one to landed cost per mg, which is list price plus a shipping estimate divided by total milligrams.
Vendor coverage for LL-37 is narrower than for the top sellers, so the gap between the cheapest and most expensive supplier can be wide. Browse related research peptides on the all peptides page, and read each vendor's transparency badges before you buy.
