IGF-1 LR3: Peptide Profile
Category: Peptide Hormone
Chemical Name: Insulin-Like Growth Factor 1 Long R3
Molecular Structure: Modified IGF-1 with an extended amino acid chain for increased stability and bioavailability.
Mechanism of Action
IGF-1 LR3 is a synthetic derivative of a naturally occurring IGF-1, a hormone primarily produced in the liver in response to growth hormone (GH). IGF-1 plays a critical role in cell growth, protein synthesis, and glucose metabolism. IGF-1 LR3 has been modified to resist binding proteins that typically inhibit IGF-1 activity, significantly extending its half-life (20-30 hours compared to IGF-1’s 12-15 minutes). This allows for prolonged anabolic effects in muscle and tissue repair.
Benefits
- Muscle Growth: Stimulates both hypertrophy (increase in cell size) and hyperplasia (increase in cell number), leading to significant muscle development.
- Fat Loss: Enhances fat metabolism and reduces body fat while preserving lean tissue.
- Improved Recovery: Accelerates tissue repair and recovery from workouts or injuries.
- Anti-Aging: Promotes collagen production and cellular repair, potentially reducing signs of aging.
- Bone Health: Encourages bone density and skeletal strength.
Dosage and Administration
Typically administered via subcutaneous or intramuscular injection. Dosages range from 20-50 mcg per day for fitness or medical purposes. It is often cycled to prevent desensitization.
Side Effects
- Hypoglycemia (low blood sugar) due to increased glucose uptake.
- Joint pain or swelling from tissue growth.
- Potential organ growth with prolonged misuse.
- Cancer risk in individuals with pre-existing conditions, as IGF-1 promotes cell proliferation.
Legal Status
IGF-1 LR3 is not approved for general use and is considered a research chemical. Its use is prohibited in most competitive sports and heavily regulated in many countries.
Conclusion
IGF-1 LR3 is a powerful peptide with extensive anabolic and recovery benefits but requires cautious use due to its potential risks.
