From muscle growth and healing to overall recovery, IGF 1 LR3 offers transformative benefits. This guide delves deep into its intricacies, exploring its role in growth and metabolism.
Join us as we embark on a journey of discovery, shedding light on the captivating world of IGF-1 LR3 and its groundbreaking properties.
Transitioning into our exploration, let’s begin with understanding the fundamentals of IGF-1 LR3.
Part 1. What is IGF-1 LR3?
IGF-1 – a potent peptide with remarkable potential. Discover its unique properties, and uncover its pivotal role in growth and metabolism. Join us as we explore the fascinating realm of IGF-1 and its groundbreaking variant, IGF-1 LR3.
a) IGF-1
Insulin-like growth factor 1 (IGF-1) is a small peptide comprising 70 amino acids with a molecular weight of 7649 Da. Like insulin, IGF-1 has an A and B chain connected by disulfide bonds. The C peptide region consists of 12 amino acids. Some properties of IGF-1 are as follows.
- IGF-1’s capacity to weakly bind to the insulin receptor can be attributed to its structural resemblance to insulin.
- Many tissues secrete IGF-1, and the secretory site determines its actions.
- IGF-1 is secreted by the liver and transported to other tissues, which acts as an endocrine hormone.
- It is assumed that IGF-1 can also act in an autocrine manner as an oncogene.
The role of IGF-1 in the metabolism of many tissues, including growth, has been reviewed recently. (Laron et al.2001)
b) IGF-1 LR3
Long(R3)-IGF-1 is an analog of IGF-1 that contains an amino-terminal peptide extension. It has an arginine substitution for glutamic acid at residue 3. The analog is biologically active in vitro and in vivo.
Long(R3)-IGF-1 resulted in marked hypoglycemia and glucose falling. In humans, it results in a severe central nervous system reaction.
In most human studies, glucose was infused with the IGF to prevent this.

With our knowledge of IGF-1 LR3’s origins, let’s delve into the remarkable mechanisms that drive its transformative effects on the body.
Part 2. How IGF-1 LR3 Works in the Body
The IGF1R receptor is a hetero-tetramer with two extracellular α subunits and two transmembrane β subunits. Upon binding, the following results are obtained.
- IGF-1 Receptor Tyrosine Kinase Activation: Upon IGF-1 binding to IGF1R, receptor tyrosine kinases (RTKs) are activated, leading to the phosphorylation of RTK tyrosine residues.
- Docking Protein Interaction: Phosphorylated tyrosine domains interact with docking proteins like insulin receptor substrates (IRS), initiating further phosphorylation.
- Pathways Activated: IGF-1 binding activates three pathways, i.e., PI3 kinase/Akt, Ras-MAPK, and PLC pathways.
- PI3K/Akt/mTOR Pathway: IRS-p85 interaction induces PI3K phosphorylation, leading to PIP2 to PIP3 conversion, activating Akt and downstream substrates for survival, synthesis, and differentiation.
- Ras-MAPK Pathway: IRS-Grb2 interaction triggers Ras activation, leading to Raf and MAPK activation for increased DNA synthesis and cell survival.
- PLC Pathway: IGF-1 activates PLC, causing PIP2 hydrolysis to IP3, triggering Ca2+ release and enhancing cell motility, migration, and proliferation.
After discussing the mechanism, knowing about IGF-1 LR3 benefits is obligatory. So let’s get started.
Part 3. Exploring the Benefits
Delving into the realm of IGF-1 LR3 benefits, we uncover its potent effects on muscle growth and overall physical well-being. Let’s explore how this hormone contributes to muscle development, injury prevention, and more.
a) IGF-1 LR3 in building muscle mass
IGF-1 LR3 has rapidly emerged as a favored solution for patients seeking enhanced muscle mass. Beyond boosting strength and expediting recovery, this hormone offers a broader spectrum of benefits. Some of the benefits of muscles are as follows.
- IGF-1 LR3 triggers hyperplasia, promoting the formation of new muscle cells.
- Fostering muscle growth improves overall muscle symmetry, addressing imbalances that can contribute to injuries.
- Alongside symmetry, it delivers substantial gains in muscle size and strength, optimizing physical performance.
- IGF-1 LR3 is potent for avoiding injuries, particularly in aging adults and young athletes.
- As a unique medication, it is virtually the sole option for effectively managing muscular asymmetry.
So, IGF-1 LR3 is applicable for building muscle, safeguarding against potential injuries, and promoting overall physical well-being.
b) Tendon Healing
IGF-1 improves tendon healing and is applied in in vitro studies. However, in vivo studies have yet to be performed.
IGF-1 has been shown for tenocytes of different species.
- Its impact on mesenchymal stem cells is small and can only be improved by combining IGF-1 with other growth factors.
- Stimulating agents such as PRP have also been the focus of in vitro and in vivo research projects.
From the studies, we conclude that IGF-1 can be used to stimulate tendon healing, particularly because of its anabolic and matrix-stimulating effects. However, more preclinical in vivo studies must be performed to pave IGF-1 application into the clinical setting.
c) Cutaneous healing in estrogen-deprived mice
IGF-1 promotes cutaneous healing in estrogen-deprived mice.
The Ovx mouse has been extensively used as a model of postmenopausal pathology. For the skin, Ovx mice display a pronounced delay in healing.
- Ovx mice with local IGF-1 also promote healing to a level comparable to systemic 17β-estradiol treatment.
- Similarly, both IGF-1 and 17β-estradiol promoted re-epithelialization.
- IGF-1 significantly reduces wound neutrophil and macrophage influx in Ovx mice to the same extent as 17β-estradiol.
As we explore the many good things about IGF-1 LR3, let’s also talk about IGF-1 LR3 side effects and how to keep it safe.
Part 4. Side Effects of IGF-1 LR3
IGF-1 plays a significant role in promoting growth; the major side effects of IGF-1 therapy are as given.
- It causes an increased risk of cancer or an acceleration of cancer development.
- The use of IGF-1 can also cause an increase in the production of acne.
- IGF-1 “like” supplements and their effects will vary from product to product as each contains different ingredients.
For better understanding, it’s a good idea to carefully check these products with a trained expert like your doctor.
Now that we understand the potential side effects of IGF-1 therapy let’s explore where to obtain high-quality IGF-1 LR3.
