IGF-1LR3 1mg
IGF-1 (Insulin-like growth factor) is an endocrine hormone that is produced in the liver. The production of IGF-1 is increased in the presence of growth hormone.


IGF-1 LR3 (1mg) – Advanced Muscle Growth & Recovery Peptide
IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg3) is a potent anabolic peptide derived from the natural hormone IGF-1, which is produced by the liver in response to growth hormone (GH). This modified version features enhanced bioavailability and a longer half-life, making it highly effective for muscle building, fat loss, recovery, and cell regeneration.

⚙️ How IGF-1 LR3 Works
IGF-1 LR3 binds to IGF receptors present in many cell types, triggering cell growth and repair. It also acts similarly to insulin by promoting nutrient shuttling into muscle cells while encouraging the body to burn stored fat for energy.
Its extended half-life (up to 20–30 hours) makes it more effective than standard IGF-1, with fewer injections required for long-lasting effects.
