Where to buy IGF-1 LR3?

What is IGF-1 LR3 ?

IGF-1 LR3, also caled IGF-1 Long R3, is a form of IGF that has been chemically altered with changed amino acids. It consists of 83 amino acids with a substation of Arg(R) for the Glu(E) at position three. Hence, the name R3. The altercations enable it to avoid binding to proteins in the body, which allows it to have a longer half-life.

However, IGF-1, full named Insulin-like Growth Factor 1, is a protein that is encoded by the IGF1 gene. It consists of 70 amino acids and is a hormone that is structured similarly to insulin. Its main function is to stimulate growth within the body due to its regulation of both cell growth and cell death.

IGF-1 LR3 is more potent than the regular IGF-1 because of the decreased binding of Long R3 IGF-1 to IGF binding proteins. Its main purpose is to increase the biological activity of IGF.

Essentially, when IGF-1 LR3 is active in the body, it functions differently in different types of tissues. For instance, in muscle tissue, it makes the muscle more sensitive to insulin’s effects, such as a reduction in fat storage. But while IGF-1 LR3 Peptide helps fat reduction, a person using it will experience weight gain because of the increase in pure-muscle weight.
