Product Description

IGF1 LR3 High Purity & USA Manufactured

IGF-1 LR3, also known as Long Arginine 3-IGF-1, is a synthetic protein and a variant of insulin-like growth factor-1 (IGF-1). The difference between IGF-1 and IGF-1 LR3 is that the latter possesses an arginine instead of a glutamic acid at the third point of its amino acid sequence. It is also more potent and can be sustained for over a day. IGF-1 LR3 peptide additionally inhibits the movement of glucose into the body cells to facilitate fat burning, as research on animals has shown.

With the rise of medical innovation, research shows that IGF-1 LR3 is a potent and effective peptide with numerous abilities.

What is IGF1 LR3?

IGF-1 LR3 is a variant of IGF-1, a product of Growth Hormone that stimulates cell growth[i] throughout the body, enabling growth and development, tissue strengthening, increased bone density, and healing.

Buy IGF1-LR3With a total of 83 amino acids, IGF-1 LR3 research peptide has an extremely low affinity for insulin-like growth factor-binding proteins and has shown rapid improvement in metabolic stability. It is thus considered to be three times more potent than IGF-1. The peptide also offers a much longer half-life of 20-30 hours[ii], whereas IGF-1 only has a half-life of 12-15 hours.


How Does IGF1 LR3 Work?

According to research, the main purpose of IGF-1 LR3 is to increase the biological activity of IGF. When the IGF-1 LR3 chemical is active in the body, it functions differently depending on the types of tissues. For example, IGF-1 LR3 used in muscle tissue would make the muscle more sensitive to the effects of insulin. On the other hand, while it has been proven to aid fat reduction, it could also cause fat increase due to muscle mass increase, as research on animals has shown.

IGF1 is mainly associated with the human growth hormone, which maintains tissue health within the body. Produced in the liver, this long peptide is made possible by the pituitary gland – a tiny stricture at the base of the brain. Its role is primarily in the endocrine system to ensure hormone production and secretion run smoothly. It also regulates water levels in the body, signals milk production in pregnant mice, and boosts the body’s metabolism. Besides that, IGF1 LR3 plays a role in sex hormone production and is an integral part of mice growth.

IGF 1 LR3 Benefits

According to research, IGF1 LR3 peptide therapy offers a number of health benefits. Although the effects may take anywhere between three and six months, numerous studies prove that igf-1 lr3 injections work efficiently with consistent use.

Here are the benefits of IGF-1/LR3 peptide, as research on animals has shown:

  • Boosts weight loss
  • Reverses insulin sensitivity
  • Accelerates metabolism
  • Improves energy levels
  • Boosts muscle growth and strength
  • Enhances sex drive and performance
  • Eases insomnia
  • Increases cognitive function
  • Helps with depression

Doctors prescribe igf peptide to help multiple health issues. As per scientific research, it may also help with growth deficiencies and suffering from muscle atrophy. In the future, researchers believe that IGF 1 lr3 muscle gains peptide will be widely available in HIV/AIDS as the disease causes severe muscle loss.

Scientists have also witnessed the following IGF-1 lr3 results with regular consumption, as per clinical studies.

Metabolic Effects of IGF1 LR3

Structurally similar to insulin, research shows that short-term use of IGF-1 LR3 can both stabilize and lower blood sugar levels.

According to their study[iii], eight healthy volunteers were tested on their responses to both IGF 1 and insulin, and the hypoglycemic responses to both hormones were almost identical in the doses used.

The most significant drop in blood glucose levels came after 30 minutes: 1.98±0.44 mmol per liter after IGF I and 1.78±0.29 after insulin.

This may even offer insight to scientists into preventing type 2 diabetes.

IGF1 LR3 Muscle Growth Effects

Recent studies show that IGF-1 LR3 is produced in response to Growth Hormone, which then induces cellular activities. Muscle growth is one response to the chemical.

According to recent scientific research, IGF-1 LR3 creates new muscle tissue by promoting protein synthesis and nitrogen retention. This results in the expansion of muscles through both hyperplasia (an increased number of muscle cells) and mitogenesis (the growth of new muscle fibers). Therefore, IGF-1 LR3 for muscle growth can certainly make muscle fibers bigger and increase the number of them, too, research has shown. Research has shown the peptide IGF-1 LR3 can even change the genetic capabilities in regard to muscle tissue and cell count.

Is IGF1 LR3 Safe?

IGF-1 LR3 is generally considered a safe product. It is intended to be a research product only and should not be used due to US law. This product should only be used for in vitro testing and laboratory experimentation by licensed, qualified professionals only. It is not a drug, food, or cosmetic.
