Description

IGF-1LR3

IGF-1LR3 (Long Arg3 Insulin-like Growth Factor-I) is a synthetic analog of human IGF-1 altered to include an extension sequence and an amino acid substitution. Heavily studied for its significantly extended half-life and decreased binding affinity to inhibitory proteins, this compound is utilized in laboratory settings to investigate cellular proliferation, muscle tissue hyperplasia mechanisms, and intracellular signaling pathways.

Muscle Growth (Hyperplasia): Unlike most substances that only increase the size of existing muscle cells (hypertrophy), IGF-1 LR3 can stimulate the creation of new muscle fibers (hyperplasia) through satellite cell activation.

Accelerated Recovery: It promotes the repair of muscles, tendons, ligaments, and even nerve tissues, significantly reducing downtime after intense training or injury.

Improved Body Composition: It encourages fat burning (lipolysis) by making muscle cells more sensitive to insulin and shifting the body’s energy source from glucose to stored fat.

Cognitive Support: Some studies suggest it acts as a neurotrophic factor, potentially improving memory, focus, and overall brain health by promoting neuronal survival.
