IGF-1 LR3
Reference profile — not currently in the Vybe catalog
Overview
IGF-1 LR3 (Long R3 IGF-1) is engineered to reduce IGF-binding-protein interaction in published cell-culture work. The sequence is an analog of human IGF-1, not native IGF-1. Formula strings vary with terminal modifications; use the certificate of analysis for the lot you hold. This is a potent research protein — not a sports protocol.
Research areas
Framed as published laboratory and clinical literature. Not treatment guidance.
IGF-1 receptor signaling
Cell-culture papers use LR3 material to study IGF1R phosphorylation, proliferation, and binding-protein interference.
Published research
Long R3 insulin-like growth factor-I (LR3-IGF-I) is more potent than IGF-I in stimulating protein synthesis and inhibiting protein degradation in L6 myotubes
