The detail

What you should know.

Description

LL-37 is the body's own antimicrobial peptide (a cathelicidin), studied for antimicrobial defence, wound healing and immune modulation.

Evidence is largely preclinical; supplied strictly for research use.

How it works: LL-37 is studied for disrupting microbial membranes and for signalling roles in immune response and tissue repair — a dual antimicrobial and immunomodulatory peptide.

Researched to support: immune defense, tissue repair, short courses.

Quality: Lyophilised (freeze-dried) powder, supplied for research use only. Our manufacturers carry out their own batch testing; we do not independently verify those results or issue certificates of analysis, so we back every order with our purity guarantee instead.

How to use

Reconstitute: Use bacteriostatic water. Add it slowly down the inside wall of the vial and let it dissolve for 10 to 15 minutes. Do not shake.

Administer: Subcutaneous, usually with an insulin syringe.

Dose example: A 5 mg vial reconstituted with 1 ml gives 0.5 mg per 0.1 ml (10 units on a U-100 insulin syringe).

Store: Keep the powder cool and dry. Once reconstituted, store at 2 to 8 °C and use within about 28 days.

Research dosing protocols

In research use LL-37 is handled as a subcutaneous injection:

  • Reconstituted with bacteriostatic water.
  • Studied in short research courses.
  • No approved human dosing exists.

Describes dosing used in clinical research, provided as reference only — not a usage recommendation or medical advice. This is an investigational research compound.

Clinical studies

Antimicrobial research: Laboratory studies explored LL-37 for disrupting bacterial membranes and supporting wound repair; human trials are limited.

Immune modulation: Research examined its signalling roles in immune responses and inflammation.

Status: An investigational research compound; supplied strictly for research use.

FAQs
What are peptides?

Peptides are short chains of amino acids (2 to 50) that act as signalling molecules. Ours are supplied for laboratory research.

What's included in my order?

The vial contains lyophilised powder only. You also need bacteriostatic water, a sterile syringe, and a needle. We stock bacteriostatic water under Supplies.

How do I reconstitute the peptide?

Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve for 10 to 15 minutes. Do not shake.

How should I store it?

Keep the powder cool and dry. After reconstitution, store at 2 to 8 °C and use within about 28 days.

How are peptides administered?

Most are administered subcutaneously with an insulin syringe, for slow, steady absorption. A few formulations use other routes.

When do effects appear?

It varies by peptide and protocol. Some are researched over a few days, others over several weeks.

Do I need to see a doctor?

A prescription is not required, but we recommend speaking with your doctor, especially if you have a medical condition or take other medication.

Are your peptides tested?

Our manufacturers carry out their own batch testing, but we do not test independently and do not hold certificates of analysis — so we make no purity claim of our own. We back it with a guarantee instead: if you want a vial independently tested, contact us first, we’ll agree a laboratory and pay for the test. If the result doesn’t match the label, we cover the testing cost and replace the product.
