Insulin-Like Growth Factor-1 (Long R3 IGF-1) is a man-made polypeptide made up of 83 amino acids. It works in the blood to help move sulphate into cartilage, which is important for growth. It’s the most useful form of IGF-1.
It plays a critical role in development and cell repairs. It also helps to promote growth by working with growth hormone (GH). Early reports indicated that growth hormone doesn’t directly cause sulphate to enter cartilage but does so by affecting a blood factor, originally called the ‘sulfation factor,’ later identified as ‘somatomedin.’
Myostatin, also referred to as growth differentiation factor 8, is a protein from the TGF beta family that stops muscle growth and development. It is mainly produced in skeletal muscle cells, released into the bloodstream, and works by attaching to a receptor on muscle cells called the activin type II receptor. In humans, myostatin is controlled by the MSTN gene. Animals without myostatin or treated with substances like follistatin, which blocks myostatin from binding to its receptor, have much larger muscles.
IGF-1 LR3, also called Long R3 IGF-1 or Insulin-Like Growth Factor-I LR3, is a synthetic protein with 83 amino acids and a molecular weight of 9200 Daltons. It is a recombinant human protein and does not have sugar molecules attached. IGF-1 plays a key role in the growth effects of growth hormone (GH). Early research showed that GH didn’t directly affect cartilage growth but worked through a substance in the blood called ‘sulfation factor,’ later called ‘somatomedin.’
IGF1 LR3 is a form of insulin-like growth factor 1. It is a human-made protein with 83 amino acids and a molecular weight of 9200 Dalton. IGF-1 helps promote many of the growth effects of growth hormone. Study shows that IGF-1 causes muscle cell hyperplasia, meaning the splitting and creation of new muscle cells, leading to more muscle cell density.
The purity is 95%, as shown by SDS-PAGE and HPLC tests. Each vial contains 1mg.
IGF-1 LR3 is crucial in how the body responds to growth hormones. GH stimulates the production of IGF-1, which then triggers various cellular actions, such as muscle growth. It even makes the body more sensitive to insulin. IGF-1 is the strongest growth factor in the body and helps in the creation of new muscle cells through a process called muscle cell hyperplasia.
Long-R3 IGF-1 is the most useful form of IGF-1 because it has been altered to prevent it from attaching to proteins in the body, which helps extend its half-life to around 20-30 hours.
