IGF-1 LR3 or also knowns as LR3-IGF-1, is a synthetic protein and lengthened analog of human insulin-like growth factor 1 (IGF-1). IGF-1, has a number of structural similarities with insulin, which is how it got its name.
The Long R3 IGF-1 version is significantly more potent than regular IGF-1 due to the decreased binding of IGF1 LR3 to all known IGF binding proteins. The IGF-1 LR3 analog of IGF-1 was created to increase the bioactivity of the IGF peptide and give it a longer half life; between 20 to 30 hours.
IGF-1 LR3 frequently gets applied in medical practice, as well as power sports to increase the power indicators of bodybuilders, boost endurance and more.
