IGF-1 LR3

IGF-1 LR3 is a modified, long-acting analogue of insulin-like growth factor 1, a hormone central to the body's growth and repair processes. The "LR3" modification extends the peptide's activity in the body, allowing for a more sustained anabolic effect than naturally occurring IGF-1. This makes it a peptide of considerable interest for those focused on supporting muscle hypertrophy, strength, and lean tissue development. Beyond muscle growth, IGF-1 LR3 is also studied for its role in supporting nutrient uptake within muscle cells, contributing to a more efficient use of the calories consumed to build tissue. 48x Labs offers IGF-1 LR3 with exceptional purity, giving you a potent option for those exploring advanced muscle-building peptide protocols.
