IGF-1 LR3 0.1mg per vial

IGF-1, or insulin-like growth factor, is a potent growth factor found in mammalian blood. This peptide manages and regulates growth hormone levels (GH). IGF-1 LR3 is a shortened form of IGF-1, and some researchers recognized it as a most potent growth factor.

IGF-1 LR3 is an 83-amino acid chemically altered amino acid chain. At position 3 on the chain, Glu(E) was replaced with Arg(R), giving rise to the name LR3. Making this substitution at position three prevents IGF-1 from binding proteins, increasing the half-life.
