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."Last edited by Blown_SC; 03-01-2005 at 01:22 AM.
