igf-1 lr3 (100mcg)

IGF-1 LR3 is a synthetic, longer-acting analog of Insulin-like Growth Factor 1 (IGF-1) used in research and by some athletes for muscle growth, fat loss, and tissue repair, as it binds less to binding proteins, increasing its biological activity and half-life. This modified peptide promotes anabolic effects like muscle cell proliferation (hyperplasia) and fiber development, enhances nutrient partitioning to muscles, and helps with recovery, though it's often sold as a "research chemical" and not for human consumption due to potential side effects and lack of established safe dosages for performance enhancement
