Anybody who's into bodybuilding or research has probably heard of IGF-1, which stands for insulin-like growth factor. IGF-1 is a growth-promoting polypeptide that plays a key role in promoting muscle growth, development and healing.

Furthermore, it's also a major hormonal mediator that supports statural growth in children. I don't think too many children have subscribed to this newsletter, though, so we'll keep the bone-growth discussion to a minimum.

Under normal instances, growth hormone (GH) attaches itself to its receptors located in the liver and other tissues and rouses the synthesis of IGF-1. In target tissues, the Type 1 IGF receptor, which is homologous to the insulin receptor, gets triggered by IGF-1.

This action leads to intracellular signaling that goes ahead and promotes stimulation of a variety of process that all lead to muscular and/or statural growth (in children). IGF-1 metabolic actions are concentrated at motivating glucose, amino acids and fatty acids uptake; this cause of action helps the metabolism support tissue growth. Summing everything up here, IGF-1 is made in response to GH and helps the latter have a very positive effect on muscle and/or bone growth (in children).

Now we come to the peptide known as IGF-1 Long R3, which some researchers might not be so familiar with….

How do IGF-1 Long R3 and regular IGF-1 differ?

Normal IGF-1 consists of 70 amino acid chains and is structurally similar to insulin, hence the "insulin-like" part of the name. IGF-1 is an exceptional anabolic peptide that performs insulin-like actions such as transporting certain amino acids and glucose into the correct muscle cells, where they are proposed and turned into new muscle tissue.

IGF-1 Long R3 is a chemically altered version of IGF-1 that's designed to be more powerful. This peptide features 83 amino acid chains, with Arg(R) in place of Glu(E) at position three, which is where the "R3" comes from. The R3 allows this peptide to avoid binding to proteins, thus giving IGF-1 Long R3 a longer half life – usually over 20 hours, as opposed to IGF-1's half life of 20 minutes.

What you get with IGF LR3 is a long-acting, extremely potent peptide that works to increase muscle mass and make muscle tissue more sensitive to insulin, often producing a decrease in fat storage.

IGF-1 Long R3 Benefits:

It gathers fat that is then used as energy in adipose tissue.
Has the power to restore impaired tendons.
Promotes and stimulates protein synthesis.
Causes hyperplasia, which is in essence the upsurge of more muscle cells.
Responsible for muscle mass building and stimulates/enhances fat loss.
IGF-1 Long R3 transports nutrients straight into cells and muscles, thus further promoting maximum results.

IGF-1 Long R3 forms a great stabilizer that promotes cellular culture. The IGF-1 LR3 peptide easy adapts to numerous cell varieties and has quality effects that are essential for growth. The LR3 forms up a lasting analog of human IGF-1 that was created for mammalian cell culture that facilitates large-scale development of recombinant biopharmaceuticals.

The recombinant Human LR3 insulin, such as the Growth factor-1 which is generated from the E.Coli, serves as a solo non-glycosylated polypeptide chain that carries 83 amino acids and contains a molecular mass of 9.1 Da.

Long R3 IGF-1 is capable of performing a variety of functions such as:

Increasing RNA
Increasing Protein Synthesis
Promoting Fat Metabolism
Promoting Sugar Transport
Promoting efficacy of Nutrient Intake

Long R3 IGF-1 plays a positive role in the promotion of muscle tissue, plus it supports and multiplies nitrogen retention and augmented food conversion. It generally helps the body make use of nutrients in a more efficient manner.

The remarkable abilities of Long R3 IGF-1 are boosted by the addition of Growth Hormone (GH). As the body undergoes puberty, IGF oversees natural muscle growth that occurs during these years. There are a variety of things that get done by IGF in the human body.

Benefits of IGF-1 in General:

The most positive effects include the following: increased amino acid shuttling to cells, doubled glucose transportation, tripled protein synthesis, decreased protein deprivation and increased RNA synthesis.

When IGF-1 becomes active, it acts differently in separate tissue masses. When it comes to muscle cells, proteins and associated cell components become stimulated. Protein synthesis gets amplified alongside amino acid immersion.

When it comes to energy production, IGF-1 consolidates fats for use as energy in adipose tissue. When it comes to lean tissue, IGF-1 stops insulin from shuttling glucose across cell membranes. This move ensures that the cells are left with the option of burning off fat as a source of energy.

IGF-1 also takes up the role of insulin in the body. It helps muscles become rather sensitive to insulin's effects. This role has helped many insulin users minimize their insulin dosage by a specific margin; however, they attain the equivalent effects.

The most outstanding and interesting potent effect that IGF-1 has on the human body is its capability to cause cells to split (Hyperplasia). This process results in major muscle growth.

As you can see, IGF-1 and its altered peptide form of IGF-1 Long R3 have the strong ability to help test subjects pack on muscle and shed fat.
