Insulin-like Growth Factor 1, or IGF-1 for short, is a protein encoded by the IGF1 gene. It contains 70 amino acids and is a hormone with a structure very similar to insulin. Due to its regulation of cell division and cell death, its primary function is to stimulate growth within the body.
Synthetic IGF-1 is an alternative to the pituitary gland’s exclusive production of Human Growth Hormone (HGH). The function of the pituitary gland declines with age, but IGF-1 produces the same effects as growth hormone without the pituitary gland.
IGF-1 Long R3, or IGF-1 LR3, is a form of IGF in which the amino acids have been chemically altered. It consists of 83 amino acids, with Arg(R) serving as a substation for Glu(E) at position three; hence, the name R3. The alterations prevent the drug from binding to proteins in the body, thereby extending its half-life [R].
IGF-1 LR3 is more potent than regular IGF-1 because Long R3 IGF-1 binds less strongly to IGF-binding proteins. Its primary function is to enhance IGF’s biological activity. Additionally, IGF-1 LR3 peptide inhibits the movement of glucose into cells to promote fat burning. In terms of purity, the difference between the media and the receptor is >85% and >95%, respectively.
A recent study utilizing mice with GH receptor KO gene showed that IGF-1 administration stimulates the growth (width) of the tibial growth plate and that IGF-1 has a GH independent effect on the growth plate. These findings are similar to those found when treating hypophysectomised rats with IGF-1 [R].
IGF-1 LR3 Research Peptide
IGF-1 LR3, or Long R3 Insulin-Like Growth Factor-1, is a modified version of the naturally occurring insulin-like growth factor-1 (IGF-1). IGF-1 LR3 has a longer half-life and increased potency compared to native IGF-1.
Insulin-like growth factor I (IGF-I) is essential for the development and growth of numerous tissues. IGF-I coordinates with other growth factors to promote myoblast proliferation, differentiation, and fiber formation in skeletal muscle during normal growth and regeneration after injury. These actions can also lead to muscle hypertrophy, which enhances the functional capacity of skeletal muscle. Consequently, IGF-I is a key therapeutic target for enhancing muscle function in aging and disease and for accelerating repair following acute damage.
IGF-1 is synthesized primarily in the liver and is expressed locally in peripheral tissues under the control of pituitary growth hormone (GH). IGF-1 appears to modulate GH secretion via a negative feedback mechanism. The GH/IGF-1 signaling pathway is essential for the maintenance of anabolic processes in adults and normal growth in children. Six binding proteins (IGFBPs) with separate biological functions influence the bioavailability and bioactivity of IGF-1.
IGF-1 LR3 works by binding to the insulin receptor and the IGF-1 receptor on the surface of target cells, like muscle cells. This binding starts a chain of events inside the cell that help it grow and divide. IGF-1 LR3 makes satellite cells multiply in muscle cells. Satellite cells are a type of stem cell that lives in muscle tissue. These satellite cells can change into muscle cells and join up with existing muscle fibers, which helps muscles grow and get better.
IGF-1 LR3 also helps muscle cells make more protein, which makes the muscles bigger and stronger. Also, it can slow down muscle breakdown by stopping the proteins involved in muscle proteolysis from doing their job.
Multiple animal and cell-based studies have been conducted on IGF1 LR3 (Media Grade). This research chemical has also been the subject of clinical research. All these pieces of research have shown that IGF1 LR3 (Media Grade) can potentially improve body mass, fat loss, retinal degeneration. muscle wasting and address age related muscle function
However, in the absence of randomized, large-scale, placebo-controlled trials, the FDA is yet to approve IGF1 LR3 (Media Grade) for human consumption. Therefore, Behemoth Labz sells IGF1 LR3 (Media Grade) for laboratory and research purposes, not for human use.
As we grow older and enter middle and later years of life, our body experiences various changes, which may include a decrease in muscle mass and an increase in fat accumulation. To study this phenomenon, a research project was conducted involving 21 healthy men aged between 61 and 81 years old. These individuals had plasma IGF-I concentrations of less than 350 U per liter during a six-month base-line period and a six-month treatment period that followed. In this study, the participants were divided into two groups: the first group received human growth hormone for six months during the treatment period, while the second group did not receive any treatment. The results of the study showed that the administration of human growth hormone in the first group resulted in an 8.8 percent increase in lean body mass, which is an indicator of an improvement in muscle mass. [R]
Despite the fact that this study provides evidence that human growth hormone may improve muscle mass in older individuals, additional research is still required to fully comprehend this hormone’s effects on the body.
According to a previously mentioned study, the group also experienced a significant reduction in adipose-tissue mass of up to 14.4 percent. This decrease in plasma IGF-I concentrations is a normal aspect of the aging process in adults in good health. On the basis of these findings, it can be concluded that the decline in growth hormone secretion contributes to the loss of lean body mass and its constituent organs, as well as the common increase in adipose tissue in older adults. Interestingly, growth hormone administration led to a reduction in body fat. [R] However, additional research is necessary to gain a comprehensive understanding of these intricate processes.
Both insulin-like growth factor (IGF-1) and chronic inflammation are associated with the age-related decline in physical performance. When both low IGF-1 levels and chronic inflammation are present, the risk of progressive disability is increased. Age-related increases in inflammatory cytokines result in a state of subclinical inflammation. The upregulation of the inflammatory response plays a significant role in the decline of physical performance associated with aging. Interleukin-6 (IL-6) is a major proinflammatory cytokine that has detrimental effects on muscle function. Studies in vitro indicate that IGF-1 may mediate the negative effect of IL-6 on muscle function. Recent research confirms that elevated levels of multiple catabolic biomarkers, such as IL-6, are significant predictors of the age-related decline in muscle strength. In elderly subjects, elevated levels of TNF- and IL-6 and low levels of IGF-1 are associated with an increased mortality rate. [R][R]
A study was done to find out how closely insulin-like growth factor-1 (IGF-1), inflammation, and retinal degeneration are related. IGF-1 is an important part of keeping the retina healthy, and its lack has been linked to a number of diseases that cause the retina to deteriorate. The pathogenesis of retinal degeneration also includes chronic inflammation. Studies show that IGF-1 can stop inflammation and change how the retina reacts to inflammation. The article comes to the conclusion that IGF-1 and inflammation are closely linked, and that targeting this network could lead to possible treatments for diseases that damage the retina. [R]
The relationship between IGF-1, inflammation, and retinal degeneration is complex and needs further study. IGF-1 deficiency and chronic inflammation may contribute to retinal degeneration, but more research is needed to determine the extent of this relationship and how it can be targeted for treatment.
Muscle atrophy and wasting are common among patients with chronic debilitating illnesses, burn injuries, spinal injuries, and space travel. Current treatment options include nutritional supplements and physical therapy, but they have limited efficacy. Anabolic growth factors such as insulin-like growth factor (IGF-1) have gained popularity for preventing muscle atrophy, but their use is constrained by adverse effects such as hypoglycemia. However, the formulation of IGF-1 used in this study is bound to its endogenous-binding protein (BP3), which increases its specificity and diminishes its hypoglycemic effects. In a rat model of hind limb suspension, the administration of IGF-1/BP3 led to the preservation of greater body and muscle mass and a decrease in muscle protein degradation. The study suggests that IGF-1/BP3 may be useful for inhibiting muscle proteolysis under catabolic conditions, thereby preserving the protein content and mass of muscle tissue. It is important to note that additional research is required to confirm these results.[R]
The half-life of IGF-1 LR3 is between 20 and 30 hours. It has greater strength than the basic form of IGF-1.
Most of the major sports organizations, like the World Anti-Doping Agency (WADA) and the International Olympic Committee, say that IGF1 LR3 can’t be used to improve performance (IOC).
IGF1 LR3 is not a drug that has been approved by the Food and Drug Administration (FDA). It is thought of as a performance-enhancing drug, and athletes and bodybuilders often use it to help them build muscle and do better in sports. But it is available for research and is used in scientific studies to learn more about how it works and how it might be used in therapy.
Insulin-like growth factor 1 (IGF-1) is considered the most potent growth factor in the insulin family. Its role is to promote cell proliferation and differentiation, particularly in muscle cells. IGF-1 LR3 is a synthetic form of IGF-1 that is modified to have a longer half-life in the body, which enhances its effectiveness. Unlike regular IGF-1, which has a half-life of only a few minutes, IGF-1 LR3 can remain active for up to 20-30 hours. Additionally, IGF-1 LR3 is typically of higher purity and receptor grade than natural IGF-1, as it is produced in a laboratory setting and subjected to rigorous quality control measures. These measures can include terminal amino acid analysis to confirm the identity and purity of the compound.
Overall, IGF-1 LR3 has several advantages over natural IGF-1, including its longer half-life, higher potency, and greater purity.

Insulin-like growth factor (IGF) is a hormone that plays a vital role in muscle growth and development. It activates the insulin receptor and other cell surface receptors to promote cell division and differentiation of generic stem cells into muscle cells. IGF also stimulates the proliferation of stem cell progeny, which contribute to muscle hypertrophy. Through these mechanisms, IGF contributes to muscle cell repair and regeneration, and overall muscle growth.
