Overview of IGF-1 LR3
IGF-1 LR3 (Insulin-like Growth Factor 1 Long Arg3) is a synthetic analog of natural IGF-1. It is developed to have a longer half-life and greater potency. The native IGF-1 is rapidly broken down, but when it comes to IGF-1 LR3, it remains active for 20 to 30 hours in research models. This version of IGF-1 acts directly on skeletal muscle and other tissues to stimulate cellular growth and protein synthesis in test models.
IGF-1 LR3 has been noted to promote muscle fiber growth, activate satellite cells, and increase tissue repair in preclinical studies. It also affects metabolic pathways, nutrient uptake, and cellular regeneration in experimental models.

IGF-1 LR3’s Mechanism of Action in Research Models
IGF-1 LR3 works by binding directly to IGF-1 receptors on skeletal muscle, bone, and other tissues in research models. This interaction activates signaling pathways that drive cellular growth, protein synthesis, and tissue remodeling in research. It promotes satellite cell activation and muscle fiber hypertrophy. Studies also note its effects on metabolic activity, which include improved nutrient uptake and modulation of fat metabolism in test models.

Frequently Asked Questions
Is IGF-1 LR3 legal in the United States?
IGF-1 LR3 is not approved by the FDA for human use in the United States. That means this compound cannot legally be prescribed or used as a drug or supplement for humans. IGF-1 LR3 exists as a research chemical, and it is only available for research purposes.
What does IGF-1 LR3 do in research models?
IGF-1 LR3 is studied to promote cell growth and survival in test models. This peptide interacts with IGF-1 receptors and increases protein production and tissue growth in research models.
What is the difference between IGF-1 and IGF-1 LR3?
IGF-1 LR3 is a modified version of IGF-1. It stays active for a longer period and is more potent than regular IGF-1 in research models. IGF-1, on the other hand, works faster but is broken down more quickly.
Is IGF-1 LR3 safe in research?
IGF-1 LR3 is studied in research models, and its safety is not fully established. However, higher doses may result in unwanted effects such as abnormal tissue growth and organ stress in test models.
What is the best place to buy IGF-1 LR3 online?
Researchers recommend getting IGF-1 LR3 from reputable sources. Iron Mountain Labz is a preferred option because our products are tested for their ingredients’ purity and potency in research. We sell our peptide products in different forms, such as nasal sprays and injectables, for research purposes.
