The most effective

form of IGF is Long R3 IGF-1, it has been chemically

altered and has had amino acid changes which cause it

to avoid binding to proteins in the human body and

allow it to have a much longer half life, around 20-30

hours. "Long R3 IGF-1 is an 83 amino acid analog of

IGF-1 comprising the complete human IGF-1 sequence

with the substition of an Arg(R) for the Glu(E) at

position three, hence R3, and a 13 amino acid

extension peptide at the N terminus. This analog of

IGF-1 has been produced with the purpose of increasing

the biological activity of the IGF peptide."



"Long R3 IGF-1 is signifacantly more potent than

IGF-1. The enhanced potency is due to the decreased

binding of Long R3 IGF-1 to all known IGF binding

proteins. These binding proteins normally inhibit the biological actions of IGF's."
