LL-37

LL-37 10mg is supplied as lyophilized powder under nitrogen. Typical reconstitution is in sterile or bacteriostatic water; the exact concentration depends on your protocol. Our free reconstitution calculator computes mL per dose and insulin-syringe units from any combination of vial size, water volume, and target dose.

Batch LL-2606 of LL-37 10mg is verified at 99.0% HPLC main-peak purity, with confirmation of molecular weight by LC-MS and endotoxin screening by LAL assay. One vial of every batch is also shipped to an independent US-based third-party lab for blinded re-verification. The full COA — including the chromatogram, mass spec trace, and third-party report — is bundled with your order as a downloadable PDF.

All orders ship cold-chain via DHL Express from our Guangzhou facility. Cold-pack is validated to hold under 8°C for 96 hours. Customs duties are prepaid by us — no surprise charges on delivery. Estimated transit time is 7-10 business days door to door. Tracking number is emailed when the shipment is scanned by DHL.

ACH bank transfer (2% off, recommended), USDC / BTC / ETH crypto (5% off), Zelle, CashApp, Venmo, or wire transfer for institutional orders. We do not accept credit cards because card processors prohibit research-peptide merchants in their terms of service. Full payment-method details are on the shipping & payment page.

LL-37 can be studied alone or in combination with other tissue repair peptides depending on your research design. Common pairings appear in published literature; the Vesta catalog includes pre-bundled stacks for the most-cited combinations.

Most published rodent studies in tendon and ligament repair use peri-lesion subcutaneous or intramuscular administration to concentrate the molecule at the repair site. Systemic (sub-Q at a distant site) administration is also reported, particularly for studies probing systemic immune or gut effects. Choice of route depends on the experimental question.
