IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a highly potent analog of natural IGF-1. It has been modified to increase its biological activity and half-life, allowing it to remain active in the body for over 20 hours compared to the few minutes of native IGF-1.
This synthetic peptide plays a crucial role in muscle growth, cellular repair, and recovery. It is extensively researched for its ability to stimulate protein synthesis, satellite cell activation, and muscle fiber hypertrophy. IGF-1 LR3’s long-acting nature makes it ideal for studies focused on systemic anabolic effects.
