About IGF-1LR3
IGF-1 LR3 (Insulin-like Growth Factor 1 Long R3) is a powerful peptide designed to mimic IGF-1, a natural hormone vital for muscle growth and tissue repair. With an extended half-life, IGF-1 LR3 provides prolonged anabolic effects, supporting increased muscle mass, enhanced fat metabolism, and faster recovery from physical exertion and injuries. Additionally, it contributes to improved bone density, skin health, and overall cellular regeneration, promoting youthful vitality. IGF-1 LR3 is widely used in performance enhancement and anti-aging protocols due to its comprehensive benefits for muscular development, recovery, and general wellness, aiding individuals in maintaining active and resilient lifestyles.
Disclaimer: IGF-1 LR3 is a long, structurally complex peptide analog with protein-like characteristics. Because of its length and disulfide-dependent folding, closely related folded, oxidized, or structurally similar variants may not be fully separated by a single routine RP-HPLC method. For that reason, this product is not held to a blanket 99% purity rule and is instead released against a third-party RP-HPLC specification of not less than 90.0% purity.
