What is IGF-1 LR3?
Insulin-like growth factor-1 Long R3 (IGF-1 LR3) is a modified version of the naturally occurring insulin-like growth factor-1 (IGF-1). It is a synthetic peptide hormone that has been shown to have anabolic effects on muscle tissue, meaning it helps promote muscle growth and repair. IGF-1 LR3 differs from regular IGF-1 in that it has an additional 13 amino acids on its N-terminal end, which increases its half-life and bioavailability in the body. This makes it more effective at promoting muscle growth than regular IGF-1.
Difference between regular IGF-1 and Long R3 IGF-1
The main difference between regular IGF-1 and Long R3 IGF-1 is their molecular structure. Regular IGF-1 has 70 amino acids, while Long R3 IGF-1 has 83 amino acids due to the addition of 13 amino acids on its N-terminal end. This modification increases the half-life of the hormone, making it more potent and longer-lasting in the body.
Long R3 IGF-1 has a lower binding affinity for binding proteins such as IGFBP-3, which means it can circulate freely in the bloodstream and exert its anabolic effects on muscle cells without being inhibited by these binding proteins. Overall, these differences make Long R3 IGF-1 a more effective supplement for promoting muscle growth compared to regular IGF-1.
Molecular structure and weight of IGF-1 LR3
IGF-1 LR3 has a molecular weight of 9,200 Daltons and a molecular structure that is similar to insulin. It is composed of 83 amino acids, with an additional 13 amino acids at the N-terminal end compared to regular IGF-1. The addition of these amino acids increases the half-life of the hormone, allowing it to remain active in the body for longer periods of time.
