IGF-1 LR3 is a synthetic protein, an analogue of a natural IGF-1, a hormone with anabolic function. In the body, is produced in the liver upon stimulation by somatotropin. IGF-1 LR3 is more stable than its natural counterpart and has a lower affinity to transport proteins, so it is broken down more slowly and lasts longer in the target tissues. This makes it up to 3 times more effective than its natural counterpart. It supports new muscle fibre growth and increases the volume of existing ones. It accelerates lipid metabolism. It inhibits myostatin and thus helps to regenerate and gain a greater muscle volume.
