IGF-1 LR3 — 1mg

IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a synthetic, extended-half-life analogue of IGF-1. It has been engineered to resist binding to IGF-binding proteins, resulting in significantly prolonged biological activity. It is one of the most potent anabolic research peptides studied for muscle growth, cellular repair, and metabolic regulation.

Mechanism of Action

• IGF-1 receptor agonist: Binds IGF-1R with high affinity to activate downstream anabolic signaling
• PI3K/Akt/mTOR pathway: Stimulates protein synthesis and inhibits muscle protein breakdown
• Extended half-life: Reduced IGFBP binding results in ~20-30x longer activity than native IGF-1
• Satellite cell activation: Promotes muscle stem cell proliferation and differentiation

Research Areas

• Skeletal muscle hypertrophy and repair
• Anabolic signaling and protein synthesis
• Bone density and cartilage regeneration
• Neuroprotection and CNS repair
