What is IGF-1 LR3?

IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a synthetic derivative of human IGF-1, specifically engineered to extend biological activity and reduce deactivation by binding proteins.

This molecular modification allows researchers to study sustained IGF receptor activation, protein synthesis, and cellular regeneration mechanisms across multiple tissue types.

Key Functional Modifications:

• Addition of 13 amino acids at the N-terminus

• Substitution of Arginine for Glutamic Acid at position 3

• Enhanced stability in biological environments

• Extended receptor binding for long-duration activity

Key Features

• 💎 Receptor Grade (≥98% Purity) – HPLC and Mass Spectrometry Verified

• 🧬 10x longer half-life than native IGF-1

• ⚗️ Reduced IGFBP binding = higher biological availability

• 🔬 Supports advanced cell regeneration and protein synthesis research

• 🌡️ Supplied as lyophilized vials for long-term stability

Mechanism of Action

IGF-1 LR3 binds directly to the IGF-1 receptor (IGF1R), stimulating the PI3K-AKT-mTOR signaling cascade, a critical pathway for cell growth, survival, and tissue regeneration.

Unlike native IGF-1, the LR3 variant resists degradation by IGF-binding proteins, resulting in sustained receptor activation and extended anabolic signaling.

In research models, IGF-1 LR3 demonstrates:

• Increased protein synthesis and cellular growth

• Enhanced muscle regeneration and recovery

• Improved tissue healing efficiency

• Activation of metabolic and longevity pathways

Research Applications

(Strictly for laboratory research use. Not for human consumption.)

• Muscle cell hypertrophy and regeneration studies

• Tissue repair and healing mechanism research

• Protein synthesis and metabolic regulation modeling

• IGF-1 receptor pharmacokinetic and pharmacodynamic studies

• Longevity, anti-aging, and performance research
