About immune peptides

Thymosin Alpha-1 is a 28-amino-acid thymus peptide approved in several countries as Zadaxin and studied for T cell function. Thymalin is the thymus peptide complex from the Leningrad bioregulator program, and Vilon is the dipeptide Lys-Glu from the same school.

LL-37 is the only human cathelicidin, an antimicrobial peptide that punches holes in bacterial membranes. VIP is a 28-amino-acid neuropeptide with strong anti-inflammatory effects, and KPV is the three-amino-acid tail of alpha-MSH.
