Lab resultsLL-37, explained
LL-37 is a human host-defense peptide studied in microbes, immune signals and skin-cell movement.
What it’s used for
Wound research
A topical ulcer trial had no overall benefit; subgroup findings differed.
Microbial research
Lab research examines effects on microbes and immune cells.
Form distinction
Its COVID example used engineered bacteria that produced an oral form.
Community reports
Gut and infection-related accounts included both improvement and worsening.
- Research interests
- Wound healing · Skin wounds · Immune response
Topical wound trials have mixed results; systemic benefits are unproven.
Side effects & safety
Side effects
- Worse brain fog, described by one user
Stop and get help if
- Spreading inflammation, an allergic reaction or flu-like symptoms that don't go away
- Signs of infection at the injection site
- A wound that gets worse: pus, more warmth or redness, unusual pain, a skin rash or slower healing
What regs say
- The FDA has flagged immune-reaction and impurity concerns for LL-37.
- The FDA cites lab and animal signals of tumor promotion in some tissues and male-reproductive concerns; the risk in people is unknown.
Avoid or check first
- Taking immunosuppressants — combined safety hasn't been studied
In sport
- The reference reports: likely banned at all times.

How to mix and store it
How many units do I draw?
How to mix5 steps
Wipe both tops
Wash your hands, then swab both rubber vial tops with alcohol. Let them dry.
Draw the water
Use a new sterile syringe to draw the water volume selected in the calculator.
Run it down the wall
Introduce the water slowly down the inside glass wall, rather than directly onto the powder.
Swirl, don’t shake
Gently swirl or roll the vial. Allow time for the powder to dissolve.
Label the vial
Write the preparation date and the amount and final volume on the vial label.
Injecting under the skinWhere, rotating sites, which syringe
Where
Subcutaneous injections go into the fatty layer beneath the skin. Common sites include the abdomen, outer thigh and upper arm. Keep at least 5 cm from the navel and avoid bruised, irritated or damaged skin.
Rotate sites
Change the spot each time. Clean the skin and let it dry.
Single-use equipment
Use a new sterile needle and syringe each time. Place used needles in a sharps container.
Storage
Storage
Refrigerated at 2–8°C. Reported period: 30 days.

What the research says
Skin-cell expression
Researchers found LL-37, a human peptide that acts against microbes, in skin cells.
Skin-cell movement
Lab-grown skin cells moved after LL-37 exposure, alongside changes in the EGFR cell signal.

Questions
What does 10mg mean?
It describes an amount of material in the unit stated on the label. It does not describe liquid volume, a dose, or how to prepare the product.
Read more about amountsDoes purity mean it is sterile?
No. Purity and sterility require different tests. An endotoxin result also does not establish sterility.
About testingCan I calculate concentration?
You need a mass in mg and either a final volume or a target concentration. IU and blends require separate, verified information.
