IGF-1LR3

GF-1 LR3 (Insulin-like Growth Factor 1 – Long R3) is a synthetic version of the natural IGF-1 hormone, modified to last longer in the body and have stronger effects.

It promotes muscle growth, fat loss, and cell repair. IGF-1 LR3 works by increasing protein synthesis and supporting the development of new muscle cells (hyperplasia), not just muscle fiber growth — which makes it popular for bodybuilding and recovery.

It can also improve recovery after training, joint and tendon healing, and overall tissue regeneration. Some users report enhanced endurance, better pumps, and leaner physique over time.

Because it stays active much longer than natural IGF-1, it has a greater overall anabolic effect. However, proper dosing and timing are important to avoid side effects like low blood sugar.
