About IGF-1 LR3

IGF-1 LR3 is a modified version of insulin-like growth factor 1 (IGF-1) with an extended N-terminal sequence (13 additional amino acids) and an arginine-to-glutamic acid substitution at position 3. These modifications dramatically reduce binding to IGF-binding proteins (IGFBPs), resulting in a half-life of 20-30 hours (vs 12-15 hours for native IGF-1) and approximately 3x greater potency. It is one of the most potent anabolic peptides available and is WADA-banned.

Mechanism

IGF-1 LR3 binds to IGF-1 receptors on target cells with high affinity, initiating tyrosine kinase signaling that activates the PI3K/Akt/mTOR pathway, increasing protein synthesis, glucose uptake, and cellular survival while inhibiting muscle protein breakdown (anti-catabolic). Its low affinity for IGFBPs means more free circulating IGF-1 LR3 is available for receptor activation compared to native IGF-1. It promotes satellite cell proliferation and differentiation in skeletal muscle (hyperplasia — new muscle cell formation, not just hypertrophy), enhances nutrient partitioning toward lean tissue, and has insulin-like effects on glucose metabolism.
