IGF-1 LR3 1mg

IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3)

IGF1-LR3 (Insulin-like Growth Factor-1 Long R3) is a modified version of the hormone known as Insulin-like Growth Factor (IGF or IGF-1). IGF-1 is a hormone naturally found in your blood, which manages the effects of growth hormone (GH) in your body. The “insulin” portion of the name refers to the fact that IGF-1 has insulin-like actions in some tissues. It does decrease blood sugar levels, but not nearly to the extent that insulin does. Its fundamental mechanism is to stimulate growth, such as in epidermal, platelet-derived, and nerve growth factors. IGF’s differ from other growth factors in that they are the only ones with well-described endocrine actions in human. The endocrine system produces and releases hormones and regulates many body functions, including metabolism, growth, mood, and reproduction.

The primary difference between IGF-1 and IGF-1 LR3 is the difference in their respective half- lives. IGF-1 is only active in the system for a very short period of time, whereas IGF-1 LR3 has a much longer half life of 20–30 hours. The longer half-life is advantageous because it is more potent and its effects can be exerted throughout the entire day. IGF-1 LR3 results in better muscle growth because of its lower binding affinity for proteins like IGFBP-3.
