    Frequently Asked Questions

    For Research Use Only
    Research Use Only: All information below describes in-vitro laboratory findings. IGF-1 LR3 1mg is not an FDA-approved drug and is not intended for human consumption, therapeutic, or diagnostic use.

    IGF-1 LR3 is an 83-amino-acid Long R3 analog of insulin-like growth factor 1. The Arg³-substitution and the N-terminal 13-aa extension reduce its binding to IGF-binding proteins, which is why it is used as a reference standard in cell-culture proliferation and differentiation assays.

    Supplied as a lyophilized powder in a sealed vial and third-party tested. Store the unopened vial refrigerated (2–8°C) or frozen for long-term stability; once reconstituted, keep refrigerated and use within the compound's documented stability window.

    The IGF-1 / growth-hormone axis — used broadly in in-vitro cell-culture proliferation, myoblast differentiation, and receptor-signaling reference work.
