IGF-1 LR3 1mg

The Science of Sustained Growth: IGF-1 LR3 Explained

IGF-1 LR3 (Long Arginine 3 Insulin-like Growth Factor-1) is a highly engineered, synthetic analogue of the naturally occurring IGF-1. While the native IGF-1 molecule is a critical mediator of growth hormone (GH), its efficacy in research is often limited by a very short half-life and high affinity for inhibitory binding proteins. IGF-1 LR3 solves this through two specific molecular modifications: the substitution of Arginine for Glutamic acid at the third position and a 13-amino acid N-terminal extension.

Mechanism of Action:

IGF-1 LR3 functions as a highly potent agonist of the IGF-1 Receptor (IGF-1R). Its unique structure prevents it from binding to Insulin-like Growth Factor-Binding Proteins (IGFBPs), which normally deactivate IGF-1 in the bloodstream. By remaining “free” and active, IGF-1 LR3 boasts a significantly extended half-life of approximately 20–30 hours, compared to the mere 12–15 minutes of native IGF-1. Once it binds to receptors in muscle tissue, it triggers the PI3K/Akt pathway, stimulating systemic protein synthesis and cellular proliferation.

Technical Specifications:

• Amino Acid Count: 83 Amino Acids (Standard IGF-1 is 70)

• Molecular Formula: $C_{400}H_{625}N_{111}O_{115}S_{9}$

• Molecular Weight: $9117.60 \, g/mol$

• Purity: >99% (HPLC & LC-MS Verified)

• Form: Lyophilized Powder (1mg vial)

Applications in Human Research:

The extended activity of IGF-1 LR3 makes it a primary subject for studies involving long-term tissue regeneration and metabolic optimization:

• Muscle Repair & Hypertrophy: Research focuses on the compound’s ability to promote hyperplasia (the creation of new muscle cells) and mitogenesis (the development of new muscle fibers).

• Anti-Aging & Skin Health: Investigating its role in collagen synthesis and the rejuvenation of connective tissues.

• Metabolic Disease Research: Studies explore its potential to combat insulin resistance by improving glucose uptake and promoting the oxidation of fatty acids (fat loss).

• Myostatin Inhibition: Experimental models suggest IGF-1 LR3 may help downregulate myostatin, potentially unlocking greater levels of lean mass development.
