Summary
HGH Fragment 176-191 (also known as AOD-9604) is a stabilized, modified fragment of the human growth hormone molecule corresponding to amino acids 176–191 with an addition of a tyrosine residue at the N-terminus. It retains HGH's fat-burning properties without the anabolic, diabetogenic, or IGF-1-stimulating effects.
Vilon is a synthetic dipeptide (Lys-Glu) derived from the thymus gland extract Thymalin. The shortest immune-regulatory peptide known, Vilon modulates T-cell and NK-cell function, extends lifespan in animal models, and shows epigenetic anti-aging activity. It is one of the Khavinson peptide bioregulators.
