Product Specifications
Frequently Asked Questions
What is LL-37 5mg used for in research?
LL-37 5mg is studied for broad-spectrum antimicrobial activity, innate immune modulation, and cathelicidin biology research. It is the only human cathelicidin and a key tool for antimicrobial peptide pharmacology studies.
How does LL-37 kill bacteria in research models?
LL-37 disrupts bacterial cell membranes through electrostatic interactions with negatively charged membrane components, creating membrane permeabilization and cell death in antimicrobial research models.
Can LL-37 5mg be combined with Thymosin Alpha-1 in research?
Yes. LL-37 and Thymosin Alpha-1 are studied together for combined innate (LL-37) and adaptive (Thymosin Alpha-1) immune pathway activation in comprehensive immunology research protocols.
How should LL-37 5mg be stored?
Unreconstituted vials should be stored refrigerated at 2–8°C away from direct light. Once reconstituted with bacteriostatic water, keep refrigerated and handle under sterile laboratory conditions.
What purity standard does Beyond Health Lab use for LL-37 5mg?
Every vial of LL-37 5mg is HPLC-tested to guarantee ≥99% purity. Full Certificates of Analysis are available upon request for every batch before release.

Peptides are short amino acid chains that function as vital signaling molecules throughout the body. They play a primary role in a vast array of biological functions, including tissue regeneration, immune modulation, and intercellular communication.
In clinical research, peptides are utilized to investigate interactions with specific receptors and metabolic pathways, serving as essential tools for advanced scientific and laboratory analysis.
All products provided by Beyond Health Lab are intended strictly for research and laboratory purposes. These compounds are not approved for human consumption.
To ensure long-term stability during shipping and storage, all peptides from Beyond Health Lab are supplied in a lyophilized (freeze-dried) state.
Unreconstituted Vials: Store in a cool, dry environment away from direct light. For extended shelf life, refrigeration is highly recommended.
Reconstituted Peptides: Once prepared for research, solutions must be kept refrigerated and handled using sterile laboratory practices to maintain molecular integrity.
Stability & Purity: Proper storage and handling are critical to preserving peptide purity, stability, and experimental accuracy.
All orders are processed and shipped directly from our fulfillment center within 24 hours (Monday–Friday) to ensure fast and reliable delivery.
Transit Time: Delivery typically occurs within 2–5 business days, depending on your location and the selected shipping method.
Carrier Partners: We collaborate with trusted carriers to ensure secure and, where necessary, temperature-stable transit.
Tracking: Upon shipment, a confirmation email with a real-time tracking number is provided to monitor the package at every stage.
To ensure accuracy and consistency for research applications, each vial contains approximately 105% of the labeled peptide amount.
Formulation: All products are supplied as a lyophilized (freeze-dried) powder.
Reconstitution: Vials require reconstitution with bacteriostatic water prior to use. We do not ship peptides in a liquid state to ensure maximum stability.
Standardized Dimensions: Vials are standardized at 16mm in diameter and 38mm in height, with a maximum fill capacity of 3ml. This ensures compatibility with common laboratory storage and reconstitution tools.
Transparency and accuracy are central to our operations. All peptides offered by Beyond Health Lab undergo rigorous quality-control procedures to ensure they meet high industry standards.
Third-Party Testing: Every batch is subject to independent, third-party analytical testing for purity, identity, and consistency.
Advanced Methodology: We utilize High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry to verify that each peptide meets required research-grade standards.
Certificates of Analysis (COAs): Full COAs, including purity percentages and molecular confirmation, are available upon request for every batch before it is released.

Very solid LL37. COA matched at 99.0%. The product literature could be more detailed for research purposes, but the compound quality is excellent. Will reorder.
Dra. Valeria T. –
Nuestro HPLC independiente confirmó 99.3% en este lote de LL-37 — por encima del mínimo indicado. Limpio, estable, exactamente como predice la literatura.
Michael T. –
Top-quality LL37. Purity is everything in skin research and BHL delivers — ≥99% verified, reconstitutes beautifully, no particulates. Very happy.
