What is IGF-1 LR3?

IGF-1 LR3 is a 83-amino-acid analog of IGF-1 with an Arg3 substitution and an N-terminal extension that reduces binding to IGF binding proteins, extending its circulating half-life in research models.

03

Research Purpose

Studied for its role in IGF-1 pathway research, cellular growth signaling and muscle-research models.

Listed as research topics only. No claim is made that this compound treats, prevents or cures any condition.

04

Mechanism Overview

Activates IGF-1 receptor (IGF-1R) signaling. Its reduced binding to IGFBPs in research preparations is associated with longer functional exposure than native IGF-1 in test settings.

Comparison

IGF-1 LR3 vs IGF-1 DES: IGF-1 DES is a short-acting truncated analog with local-tissue framing, while IGF-1 LR3 has extended exposure due to reduced IGFBP binding.

Comparison is educational. No compound here is being recommended for human use.
