LL-37 dose guide

A peptide dosage chart, one peptide at a time: its dose range, how often it’s taken, a typical run and the units on your syringe. All 69 peptides in the PepVault library.

A community reference, not medical advice. Each range is what has been studied or is commonly run, never a dose for you.

LL-37 dosage

Your body's own antimicrobial peptide. In lab studies it kills bacteria, fungi and some viruses, and it also steers immune responses. Commonly reported: noticeable injection-site redness or itching, and for some a flu-like, achy feeling in the first days. As a drug it has only been tested as a topical treatment for leg and foot ulcers, with mixed results; injected LL-37 hasn't been studied in people.

Dose range
100–300 mcg (research range). Studied in research — not a recommendation.
How often
Daily: Daily or EOD
A typical run
Short cycles of 2–4 weeks due to limited data. Conservative approach advised.
How it’s taken
Vial: SubQ injection
Evidence
Emerging: Primarily preclinical / limited human data
Half-life
Unknown in humans (short; broken down by proteases)

LL-37 on your syringe

With a 5 mg vial and 2 mL of water (2.5 mg in every mL), on a 0.3 mL (30-unit) U-100 insulin syringe: the low end, 100 mcg, is 4 units; and the high end, 300 mcg, is 12 units. 50 doses in the vial at the low end. All U-100: 100 units to the mL. A U-40 syringe reads differently.
