Vial label

Copy this into your label printer.

Published research contexts for LL-37 describe 100500 mcg per administration. Descriptive only, not a recommendation.

A cationic antimicrobial peptide degraded by serum proteases; human PK is thin and estimates are rough.

An antimicrobial peptide whose evidence is preclinical; the human dosing literature is absent and circulating amounts are community-derived, so no schedule table is shown.

Modelled level — every other day

1× is the peak after a single dose.

Steady-state peak
1.00× single dose

Read off the modelled curve, not an even-interval formula

Time to steady state

About five half-lives

Administrations
