IGF-1 LR3 1mg | Long R3 Insulin-Like Growth Factor-1


Extended-activity growth factor analog for advanced signaling research


IGF-1 LR3 is a modified analog of insulin-like growth factor-1 (IGF-1) engineered for reduced binding to IGF-binding proteins and prolonged biologic activity. Compared with native IGF-1, the LR3 modification is widely used in laboratory settings to study cellular growth pathways, skeletal muscle regeneration, nutrient uptake, and tissue-repair signaling.


Because of its extended half-life and stronger receptor persistence, IGF-1 LR3 is commonly selected in research models focused on:


  • muscle cell proliferation pathways

  • satellite cell activation

  • cellular repair + regeneration

  • glucose and amino acid uptake

  • soft tissue signaling

  • collagen-support pathways

  • body-composition and metabolic research


Its prolonged activity profile makes it especially useful when evaluating longer-duration anabolic and regenerative signaling cascades in controlled experimental environments.


🔬 Key Research Highlights


  • Extended signaling compared with native IGF-1

  • Reduced IGFBP binding for improved persistence

  • Supports muscle regeneration pathway studies

  • Useful for nutrient-partitioning research

  • Commonly explored in tissue-repair models

  • High-purity lyophilized peptide presentation

  • Suitable for controlled laboratory workflows


Kit includes BAC WATER for reconstitution

  • What makes IGF-1 LR3 different from native IGF-1?

    IGF-1 LR3 has significantly reduced affinity for IGF-binding proteins, allowing for longer active signaling and improved persistence in research models.

    What is it commonly studied for?

    Popular research areas include:

    • muscle hypertrophy pathways

    • tissue regeneration

    • glucose transport

    • cellular recovery

    • metabolic signaling

    • nerve regeneration

    Is it FDA-approved?

    No. IGF-1 LR3 is supplied strictly for laboratory research purposes and is not approved for therapeutic human use.

    How should it be stored?

    Lyophilized vials should be kept frozen or refrigerated per SOP. After reconstitution, short-term cold storage is recommended
