IGF1 LR3 allows for many of the growth-promoting effects of growth hormone insulin-like growth factors also know as IGF’s. IGF-1 LR3 comprises a family of peptides (protiens) that play important roles in mammalian growth and development. IGF1 LR3 is also known as Long R3 IGF-1 or Insulin-Like Growth Factor-I Long Arg3.
The Long R3 IGF-1 version is significantly more potent than regular IGF-1. The enhanced potency is due to the decreased binding of IGF1 LR3 to all known IGF binding proteins. These binding proteins normally inhibit the biological actions of IGF’s therefore IG-1 LR3 has been shown to have increased efficacy and function .
This IGF-1 LR3 analog of IGF-1 has been created with the purpose of increasing the biological activity of the IGF peptide.
The most effective form of IGF-1 is considered to be IGF-1 LR3. This formula has been chemically altered to avoid binding to proteins in the human body, and to increase the half life, approximately 20-30 hours.
