Description
IGF-1 LR3 1mg Vial – Long-Acting Insulin-Like Growth Factor-1 Research Peptide (Research Use Only)
IGF-1 LR3 (Long R3 IGF-1) is an 83-amino-acid recombinant analog of human IGF-1 with two key modifications: an arginine substitution at position 3 and a 13-amino-acid extension at the N-terminus. These changes dramatically extend its half-life to 20–30 hours and make it up to three times more potent than native IGF-1 by reducing binding to inhibitory proteins. It is the gold-standard long-acting IGF-1 for advanced muscle, cartilage, and recovery research.
Each sterile vial contains a full 1mg of lyophilized IGF-1 LR3 at ≥99% purity (independently verified by HPLC and mass spectrometry), delivering precise, reproducible anabolic signaling in cell culture and in-vitro studies.
Key research applications:
- Muscle hypertrophy and hyperplasia models
- Myoblast proliferation and satellite cell activation
- Cartilage regeneration and joint repair studies
- Protein synthesis and nutrient partitioning pathways
- Anti-catabolic effects during caloric restriction experiments
