IGF-1 LR3
Summary
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.
IGF-1 LR3 is a synthetic analog of Insulin-like Growth Factor-1 with an extended half-life. It is one of the most potent anabolic peptides available, directly stimulating muscle cell hyperplasia and hypertrophy, and is the downstream mediator of many of GH's anabolic effects.
