IGF-1 LR3

PerformanceResearch Compound

Overview

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified version of IGF-1 with 83 amino acids (compared to 70 in native IGF-1). The modifications include an arginine instead of glutamic acid at position 3 and a 13 amino acid extension at the N-terminus, resulting in reduced IGF binding protein affinity and extended half-life.
