Summary
Sermorelin is a bioidentical synthetic peptide comprising the first 29 amino acids of naturally occurring GHRH. It is FDA-approved for diagnostic use and widely prescribed off-label for anti-aging, stimulating growth hormone production in a natural pulsatile pattern that mimics the body's own rhythm.
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.
