IGF-1 LR3 1mg

IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a synthetic, long-acting version of IGF-1, a hormone involved in growth, muscle development, and tissue repair. Compared to regular IGF-1 or IGF-1 DES, the LR3 version is modified to have a much longer half-life, allowing it to stay active in the body for extended periods and produce more sustained effects.

Because of this, it is often associated with muscle growth, improved recovery, increased protein synthesis, and enhanced nutrient utilization. It works by stimulating cellular growth and regeneration, which can support muscle development and repair after training. Unlike the DES version (which acts locally and briefly), IGF-1 LR3 has a more systemic, whole-body effect.

The “1 mg” refers to the total amount in a vial, not a standardized or medically approved dose. There are no officially established dosing guidelines for general or performance use.

However, IGF-1 LR3 carries significant health risks due to its strong biological activity. These include:

• Hypoglycemia (low blood sugar)
• Potential for abnormal or excessive tissue growth
• Increased concern about tumor growth or cancer risk, since it promotes cell proliferation
• Hormonal imbalances and possible organ stress

Other side effects may include headaches, swelling, joint discomfort, or fatigue.

Importantly, IGF-1 LR3 is not approved for general medical use and is typically sold as a research chemical, meaning its safety, purity, and long-term effects are not well established.
