Cytoprotective & Tissue-Matrix Peptides
LL-37 — Research Grade, Manufactured in the USA
LL-37 is manufactured from the ground up in our US cGMP facility and released as a lyophilized research compound. Every lot is analytically verified to ≥99% HPLC purity and ships with a batch-specific Certificate of Analysis, mass-spectrometry identity confirmation and endotoxin (LAL) screening. Supplied strictly for laboratory research use — not for human or animal consumption.
LL-37 sizes & strengths available
Minimum order is 100 vials per SKU. Milligram strengths may be mixed within a single SKU to reach the minimum.

Purity, COA & batch verification
≥99% HPLC purity
Each LL-37 lot is assayed by high-performance liquid chromatography and released only when it meets our 99% purity standard.
Batch-specific COA
Every shipment is traceable to a lot number with an accompanying Certificate of Analysis, identity confirmation and endotoxin (LAL) result.
Controlled lyophilization
Standardized freeze-drying cycles produce uniform pucks and protect peptide structure for long-term stability.
US manufacturing
Manufactured domestically rather than repackaged from imported bulk powder, so material history stays fully traceable.
LL-37 5mg reconstitution reference
Resulting concentrations when a 5mg vial is reconstituted with bacteriostatic water. Laboratory reference arithmetic only.
