{"product_id":"igf-lr3","title":"IGF-LR3","description":"\u003cp\u003eIGF-LR3 (Insulin-like Growth Factor 1, Long Arg3) is a synthetic IGF-1 analogue carrying a 13-residue N-terminal extension and an arginine swap at position 3. Together these changes sharply lower affinity for IGF-binding proteins, lengthening functional half-life and improving receptor availability — making it a workhorse in proliferation and anabolic-signalling research.\u003c\/p\u003e\n\u003cp\u003eLyophilised powder, 1mg vial, ≥99% purity by HPLC, Certificate of Analysis on request.
