IGF-1 LR3

IGF-1 is a powerful protein closely related to insulin, but with an even stronger ability to stimulate growth and build lean muscle mass. Widely recognized in the bodybuilding community, IGF-1 helps drive faster recovery, enhanced hypertrophy, and improved performance — all without the harsh side effects seen in many other compounds.

What makes IGF-1 so effective is its ability to bind to Insulin-Like Growth Factor Binding Proteins (IGFBPs) in the bloodstream. These binding proteins extend its half-life, keeping IGF-1 active longer and allowing it to deliver its growth-promoting effects directly to muscle tissue. The result is more time for your body to repair, rebuild, and grow stronger.

For athletes chasing serious gains, IGF-1 is considered one of the most potent drivers of muscle development and body recomposition, making it a trusted choice for those who demand results.
