IGF-1 LR3 1mg

Overview

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified 83-amino-acid analog of IGF-1 with an arginine substitution at position 3 and a 13-amino-acid N-terminal extension. This modification reduces binding to IGF-binding proteins, dramatically increasing bioavailability and extending half-life compared to native IGF-1. Research areas include cell proliferation, muscle hypertrophy signaling, recovery enhancement, and growth factor pathway modulation.
