Description

IGF-1 LR3 100 mcg (Insulin-like Growth Factor-1 LR3)

IGF-1 LR3 is a synthetic long-acting variant of insulin-like growth factor-1 (IGF-1) designed with an extended half-life compared to natural IGF-1. It is primarily studied and used in research contexts for its role in muscle growth, recovery, and metabolic activity.

How It Works

IGF-1 LR3 binds to IGF-1 receptors on muscle and other tissue cells, activating pathways that promote cellular growth, protein synthesis, and tissue regeneration. Its extended half-life allows it to remain active in the body longer than native IGF-1, enhancing its effects on nutrient uptake, muscle repair, and metabolic utilization.

Dosage Overview

IGF-1 LR3 is typically administered via subcutaneous or intramuscular injection. Commonly referenced dosing ranges from 50–100 mcg per day, often used on training days in cycles lasting approximately 4–6 weeks. Dosage is usually adjusted based on individual goals, response, and tolerance, with careful monitoring recommended due to its potency.

Potential Benefits

IGF-1 LR3 is associated with increased muscle growth, improved recovery, enhanced fat metabolism, and greater nutrient uptake into muscle cells. It may also support energy levels, endurance, and overall tissue regeneration, making it attractive in performance and physique-focused settings.

Side Effects and Considerations

Possible side effects include hypoglycemia, mild water retention, joint discomfort, and injection site irritation. Prolonged or excessive use may interfere with normal hormonal balance and glucose regulation. Careful dosing and supervision are recommended due to its strong metabolic effects.
