    Vendor profile

Tiers name what a vendor publishes, not a verdict on any product's purity or quality. Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do). Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site. Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score. Affiliate relationships never affect tiers, selection or order. How the Vendor Score works

A cathelicidin-derived antimicrobial peptide (CAP-18) studied in research on host-defense and wound-healing models.

Evidence brief

LL-37 is the only human cathelicidin, an antimicrobial and immunomodulatory peptide released from the hCAP18 precursor protein as part of innate host defense in skin, gut, and airways.

Multi-peptide products (e.g. BPC-157 + TB-500). We don't rank these by $/mgPrice divided by the milligrams of active compound — the like-for-like way to compare cost across different vial sizes. — a per-milligram figure across different peptides isn't comparable — so they're listed separately by total price and kept out of the headline index above.

Published dosing for LL-37

Source-linked reference figures with the population and study context alongside each amount. Study arms are not a starting dose, titration schedule, or personal treatment plan. Label records refer to the named approved medicine, not vendor products.

No curated dosing record is available for LL-37 in this index yet. That describes our coverage, not proof that no study exists. See the research and cited studies on this page.

Research use only — this reports what an FDA label or a peer-reviewed study published, tied to its species and study context. It is not medical advice, not a recommendation to use, and no dose here is generated by pepmg. Any dosing decision is for a qualified professional. Animal-study amounts do not establish a human dose.

▸ Why compare $/mg for LL-37?

Prices for this compound vary widely between vendors; comparing $/mg avoids overpaying.

▸ Reading the COA

Always check each vendor's third-party Certificate of Analysis (COA) for identity and purity.

All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label or a peer-reviewed study has published a dose, pepmg reports it with the source named, because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
