The CAS registry number for IGF-1 LR3 (Long-R3-IGF-1) is 946870-92-4
IGF-1 LR3 is a synthetic analog of human Insulin-like Growth Factor 1. Its unique chemical structure features an 83-amino-acid sequence—the native 70-amino-acid chain with an arginine substituted for glutamic acid at position 3, plus a 13-amino-acid peptide extension at the N-terminus. This modification prevents it from binding to IGF-binding proteins (IGFBPs) in the body, which significantly extends its half-life and biological activity compared to native IGF-1.

Description

IGF-1 LR3 (Long R3 Insulin-Like Growth Factor-1) is a synthetic peptide known for its potent anabolic and tissue-repair properties. By modifying the amino acid sequence, it boasts a significantly extended half-life of 20 to 30 hours compared to the 20-minute half-life of naturally occurring IGF-1. 
Key Specifications
  • Structure: Modified analog of human IGF-1; comprises 83 amino acids.
  • Potency: Roughly 3 times more potent than native IGF-1 due to reduced binding affinity to IGF-binding proteins.
  • Presentation: Available in lyophilized powder form, commonly distributed as 1mg vials for research purposes.
  • Mechanism: Encourages muscle hyperplasia (the formation of new muscle cells) rather than just hypertrophy (enlarging existing cells).
