Description
IGF-1 LR3
(Long R3 Insulin-like Growth Factor-I) 1mg is a synthetic, long-acting analog of IGF-1, engineered for enhanced stability and a 20–30 hour half-life compared to minutes for natural IGF-1. It promotes significant muscle growth (hyperplasia), enhanced recovery, and improved nutrient partitioning by limiting binding to IGF-binding proteins.
Key Details and Characteristics:
- Structure: 83-amino acid peptide, modified with an arginine at position 3 and a 13-amino acid N-terminal extension.
- Function: Stimulates muscle growth via both proliferation (cell number) and differentiation (cell maturity).
- Potency: Highly potent compared to standard IGF-1 due to reduced binding to inhibitory binding proteins.
Commonly Reported Benefits:
- Accelerated Muscle Growth: Enhances hypertrophy (size) and hyperplasia (new fiber creation).
- Improved Body Composition: Promotes nutrient partitioning, directing nutrients toward muscle tissue rather than fat cells.
- Enhanced Recovery: Supports tissue repair and faster healing from intense physical activity.
Dosage and Administration (Research Settings):
- Administration: Typically administered via subcutaneous injection.
- Dosage: Common research dosages range from 20–50 mcg daily or post-workout.
- Cycle Duration: Often used in cycles of 4–6 weeks, followed by a break, to manage desensitization.
Potential Side Effects:
- Muscle pain or soreness.
- Potential for hypoglycemia (low blood sugar).
- Fluid retention.
