IGF-1 LR3 1mg

IGF-1 LR3 (Insulin-like Growth Factor 1 – Long R3) Primary Function: Cell growth stimulation, muscle hypertrophy, anabolic enhancement Research Use: Muscle growth, wound healing, neuroprotection, cellular regeneration Molecular Formula: C400H625N111O115S9 CAS Number: 143045-27-6 Synonyms: Long R3 IGF-1, IGF-1 LR3, LR3 IGF-1 Description: IGF-1 LR3 is a synthetic analog of human insulin-like growth factor 1 (IGF-1) engineered with an arginine substitution at position 3 and an extended N-terminal chain. These modifications drastically increase its half-life and reduce binding to IGF-binding proteins (IGFBPs), resulting in greater bioavailability and a more potent anabolic effect. IGF-1 LR3 is commonly studied for muscle hypertrophy, cell regeneration, neurogenesis, and tissue repair. Mechanism of Action: Binds to the IGF-1 receptor, stimulating PI3K/AKT and MAPK pathways Promotes protein synthesis, cell proliferation, and muscle cell differentiation Inhibits programmed cell death (apo
