    1. Core Molecular & Physical Traits

    Item Details
    Full Name Long Arg3 - Insulin - like Growth Factor - 1 (IGF - 1 LR3)
    Amino Acid Composition 83 amino acids (native IGF - 1 has 70); the 3rd Glu is replaced by Arg, and 13 amino acids (MFPAMPLLSLFVN) are added at the N - terminus
    Molecular Weight 9112 Da (C₄₁₉H₆₃₈N₁₁₀O₁₂₁S₃)
    Purity ≥98% (SDS - PAGE), ≥90% (RP - HPLC); endotoxin < 0.01 EU/μg
    Formulation Lyophilized acetate salt, for subcutaneous/intramuscular injection after reconstitution
    Pharmacokinetics Half - life: 20-30 hours; low affinity for IGF - binding proteins (IGFBPs), high free bioavailability
    2. Mechanism of Action (Receptor - Mediated Signaling)
    IGF - 1 LR3 specifically binds to the IGF - 1 receptor (IGF1R) on muscle, bone, nerve, and cartilage cells, activating two core pathways:
    1. PI3K/Akt/mTOR Pathway: Promotes protein synthesis, inhibits muscle breakdown, enhances glucose/amino acid uptake, and supports cell survival.
    2. MAPK/ERK Pathway: Accelerates cell proliferation and differentiation, and boosts satellite cell activation for muscle repair.
    Its low IGFBP binding rate ensures more free hormone circulation, enabling stronger and longer - lasting receptor activation compared with native IGF - 1.
    3. Key Biological Effects (Preclinical Data)
    • Anabolic Growth: It increases muscle protein synthesis, enhances satellite cell activity, expands muscle cross - sectional area, and raises lean body mass; it also promotes bone collagen synthesis and boosts bone density.
    • Regenerative Repair: It accelerates the repair of muscle, nerve, and cartilage tissues, and protects neurons by reducing oxidative stress.
    • Metabolic Regulation: It improves glucose uptake in muscles, enhances insulin sensitivity, and promotes fat oxidation to reduce fat accumulation.
    • Anti - Catabolic Action: It curbs muscle breakdown (catabolism) during calorie restriction or intense exercise.

    4. Research Applications & Dosing

    Core Research Areas

    • Muscle hypertrophy and sports performance enhancement studies.
    • Regenerative medicine research (muscle, nerve, bone, cartilage repair).
    • Metabolic disorder studies (insulin resistance, obesity, fatty liver).
    • Aging - related sarcopenia and tissue dysfunction research.

    Typical Research Dosing (Rodents/Non - Human Primates)

    Route Dose Range Frequency Cycle
    Subcutaneous/Intramuscular 20-40 μg/day (rodents); 100-200 μg/day (larger models) Once daily 4-6 weeks, with an equal rest period

    Note: Higher doses (50-100 μg/day) may increase the risk of insulin resistance and tissue overgrowth.

    5. Safety & Precautions

    Common Side Effects (Preclinical)

    • Mild hypoglycemia (less severe than insulin).
    • Transient edema or tissue hyperplasia at the injection site.
    • Long - term high - dose use may lead to insulin resistance or organ overgrowth.

    Critical Warnings

    • For research use only, not for human clinical treatment or human consumption.
    • It is prohibited for use in sports due to its performance - enhancing properties.
    • Store at - 20°C; after reconstitution, use it up within 72 hours (2-8°C) to prevent degradation.

    ECHEMI Editorial Reference
    Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence ("arginine 3"), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) ("long"), for a total of 83 amino acids (relative to the 70 of IGF-1).
