IGF-1 LR3 1mg

IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a highly potent, synthetic analog of endogenous IGF-1. This "Long R3" variant features a 13-amino acid N-terminal extension and an arginine substitution at the third position, modifications specifically engineered to reduce binding to inhibitory proteins and dramatically extend its half-life to approximately 20–30 hours. In laboratory settings, researchers utilize this 1mg formulation to study sustained anabolic signaling, satellite cell proliferation, and the activation of the PI3K/Akt pathway, which is critical for muscle tissue repair and protein synthesis.
