RB Pharma IGF-1 Liquid

IGF-1 (Insulin-like Growth Factor-1) is an anabolic hormone that is crucial for muscle growth and repair. It stimulates muscle protein synthesis, promotes satellite cell proliferation, and protects against muscle wasting. Produced mainly by the liver in response to growth hormone (GH), IGF-1 is a key player in muscle hypertrophy (growth) and is also produced locally within muscle tissue. 

How IGF-1 works in bodybuilding

• Stimulates muscle protein synthesis: IGF-1 promotes the process of building new muscle proteins, which is essential for hypertrophy when it outpaces the rate of muscle protein breakdown.
• Increases satellite cell activity: It increases the number and proliferation of satellite cells, which are stem cells that are crucial for repairing damaged muscle tissue and creating new muscle fibers.
• Promotes muscle hypertrophy: By enhancing protein synthesis and satellite cell activity, IGF-1 directly contributes to an increase in both muscle mass and strength.
• Supports muscle repair and regeneration: IGF-1 is vital for the regeneration of skeletal muscle after injury and helps prevent muscle atrophy (wasting).
• Acts locally and systemically: It can act as a systemic hormone, circulating in the bloodstream, and also locally within the muscle tissue itself, where it is produced in response to exercise.
