IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a synthetic version of the naturally occurring peptide hormone IGF-1. It is modified to extend its half-life and increase its biological activity compared to regular IGF-1. Here's an overview of what you need to know about IGF-1 LR3:
What is IGF-1?
IGF-1 stands for Insulin-Like Growth Factor-1, which is a hormone similar in molecular structure to insulin. It plays a crucial role in growth and development, particularly during childhood, and continues to aid in muscle growth, bone density, and overall body maintenance in adults.
Why the "LR3" modification?
The "LR3" stands for Long Arg3, indicating a modification where the third amino acid in the sequence, arginine, replaces the original glutamic acid, and a 13-amino acids extension is added. This modification:
IGF-1 LR3 is often used in research and by athletes for its potential benefits, which include:
Exact dosages can vary widely depending on the purpose and the individual, but a common range for athletes and bodybuilders is between 20-100 micrograms per day. It’s crucial to start with a low dose to assess tolerance.
Administration
IGF-1 LR3 is typically administered via subcutaneous (under the skin) or intramuscular (into the muscle) injections. It is often taken once daily, in the morning or post-workout, depending on the individual’s specific goals and routine.
Side Effects
Like any potent peptide, IGF-1 LR3 can have side effects, which may include:
IGF-1 LR3 is not approved for medical use by the FDA or other governing health bodies and is classified as a research chemical in many places. Its use is banned by most sports organizations.
Conclusion
While IGF-1 LR3 has impressive potential benefits for muscle growth and recovery, it should be approached with caution due to its potent effects and potential for side effects. Understanding how to dose, administer, and monitor its use is crucial, and conducting thorough research or consulting with a healthcare provider is highly recommended for anyone considering its use.

Why the "LR3" modification?
The "LR3" stands for Long Arg3, indicating a modification where the third amino acid in the sequence, arginine, replaces the original glutamic acid, and a 13-amino acids extension is added. This modification:
- Increases its half-life from minutes (IGF-1) to about 20-30 hours (IGF-1 LR3).
- Reduces binding with IGF-binding proteins (IGFBPs), allowing more IGF-1 LR3 to remain active in the bloodstream.
IGF-1 LR3 is often used in research and by athletes for its potential benefits, which include:
- Enhanced muscle growth and repair
- Increased protein synthesis
- Improved muscle recovery after workouts
- Potential fat loss, though this is less well-documented
Exact dosages can vary widely depending on the purpose and the individual, but a common range for athletes and bodybuilders is between 20-100 micrograms per day. It’s crucial to start with a low dose to assess tolerance.

Side Effects
Like any potent peptide, IGF-1 LR3 can have side effects, which may include:
- Hypoglycemia (low blood sugar levels), since IGF-1 can affect insulin sensitivity
- Joint pain or swelling
- Carpal tunnel syndrome
- Potential for organomegaly (enlarged organs) if used inappropriately
- Nausea and headaches in some individuals
- IGF-1 LR3 should be used responsibly, ideally under the guidance of a healthcare professional.
- It’s important to monitor blood glucose levels because of its effects on insulin sensitivity.
- Ensure proper reconstitution and storage of the peptide to maintain its efficacy.
IGF-1 LR3 is not approved for medical use by the FDA or other governing health bodies and is classified as a research chemical in many places. Its use is banned by most sports organizations.
