IGF-1 LR3

IGF-1 LR3 binds to IGF-1 receptors throughout the body, triggering anabolic and growth-promoting pathways in muscle, connective tissue, bone, and organs. Its modified structure dramatically reduces its binding to IGF binding proteins (IGFBPs), which normally inactivate IGF-1 quickly—extending its active window from minutes to over 20 hours. Key mechanisms:

• IGF-1R activation → muscle protein synthesis and cell proliferation

• Inhibition of IGFBP binding → prolongs anabolic window significantly

• Satellite cell activation → stimulates new muscle fiber formation

• Anti-catabolic action → reduces protein breakdown

IGF-1 LR3 vs. standard IGF-1:

• LR3 = extended half-life (~20h vs. minutes for standard)

• LR3 = reduced IGFBP binding = more free active peptide

• LR3 = stronger and longer systemic anabolic effect
