Overview
IGF-1 LR3 is a modified, longer-acting analog of insulin-like growth factor 1, engineered with additional N-terminal amino acids and an arginine substitution that dramatically reduces its binding to IGF-binding proteins, extending its half-life roughly 100-fold compared to native IGF-1. This makes it far more metabolically active for a much longer period.
Treatments studied
Treatment categories
Muscle growth (research)
Directly activates the same growth-signaling receptors responsible for most of growth hormone's muscle-building effect.
Post-injury recovery (research interest)
Insulin-like growth signaling is studied for accelerating tissue repair after injury.
