GHRP-2 vs Vilon
Side-by-side comparison of key properties, dosing, and research.
- Summary
- GHRP-2 is a potent synthetic hexapeptide that stimulates growth hormone release by activating ghrelin receptors in the pituitary and hypothalamus. It produces one of the strongest GH pulses among GHRPs, though unlike Ipamorelin it does cause modest increases in cortisol and prolactin.
- 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.
