    IGF-1 LR3: Research, Benefits & UK Availability

    A synthetic modified analogue of human IGF-1 with extended half-life, studied in cell-proliferation, myocyte-pathway, and tissue-research literature.

    Every Peptify IGF-1 LR3 batch is independently HPLC-tested by Janoshik Analytical (Czech Republic) and ships with the batch-matched Certificate of Analysis.

    What is IGF-1 LR3?

    **Muscle repair research.** IGF-1 LR3 is the engineered IGF-1 analogue with a 13-amino-acid N-terminal extension and arginine substitution at position 3 — modifications studied for reduced binding-protein interference and an approximately 60-fold longer biological half-life.

    Research has examined satellite cell activation, myoblast differentiation, mTOR pathway modulation, protein synthesis, and cartilage regeneration outcomes. The extended half-life is the pharmacokinetic feature most exploited in published research designs requiring sustained signalling across satellite cell and mTOR pathway protocols.

    1mg lyophilised vial. 99%+ HPLC-verified purity, full analytical documentation included. For laboratory research only.

    Key Research Areas

    13 amino acid N-terminal extension added to native IGF-1 — binding protein interference reduced to near-zero in published bioavailability studies
    Approximately 60-fold longer half-life than native IGF-1 characterised; the longest-acting IGF-1 variant in published research
    Satellite cell activation and myoblast differentiation examined in muscle repair models at the same doses as binding protein assays
    Protein synthesis and degradation inhibition via mTOR pathway modulation investigated alongside muscle repair endpoints
    Peripheral tissue mediation of GH anabolic signalling characterised — studied where separating central from peripheral GH action matters

    How to Store IGF-1 LR3

    Unreconstituted (Lyophilised Powder)

    Store in a cool, dry place away from direct sunlight. For long-term storage, keep refrigerated at 2–8°C. Under these conditions, lyophilised peptides can remain stable for up to 24 months. For extended preservation beyond 24 months, store at -20°C in a freezer.

    Reconstituted (Mixed with BAC Water)

    Once reconstituted with bacteriostatic water, the peptide solution must be refrigerated at 2–8°C. Use within 4–6 weeks for optimal potency. Do not freeze reconstituted peptides as this may degrade the compound.

    General Tips

    Always keep vials upright to prevent leakage. Avoid repeated temperature fluctuations — do not leave vials out at room temperature for extended periods. Protect from light exposure by storing in the original packaging or a dark container. Label all vials with the reconstitution date.

    Frequently Asked Questions

    What is IGF-1 LR3?

    IGF-1 LR3 is a modified version of IGF-1 with a 13-amino acid extension that prevents binding to IGF-binding proteins, resulting in enhanced bioactivity and a longer half-life.

    What is IGF-1 LR3 researched for?

    Published preclinical research has examined IGF-1 LR3 in cell-proliferation, myocyte-pathway, and PI3K/Akt signalling studies. The extended half-life makes it useful in protocols requiring sustained in-vitro receptor engagement.

    What purity does Peptify supply?

    Peptify IGF-1 LR3 is 99%+ HPLC-verified, with a batch-specific Janoshik Analytical Certificate of Analysis downloadable from the product page.
