IGF-1 LR3, also known as Long R3 Insulin-like Growth Factor-1, is a modified version of the naturally occurring hormone IGF-1 (Insulin-like Growth Factor-1). Similar to IGF-1 DES, IGF-1 LR3 is a peptide that plays a crucial role in growth and development.
 
The "LR3" in IGF-1 LR3 refers to the extended half-life of the molecule due to the modification of the amino acid sequence. In this modified version, an arginine (R) replaces the glutamic acid (E) at position 3, resulting in LR3. This modification helps the peptide remain active in the body for an extended period, leading to a longer duration of action compared to native IGF-1.
 
IGF-1 LR3 Benefits
 
1. Increased muscle growth: IGF-1 LR3 has been studied for its ability to enhance muscle hypertrophy (muscle growth) by stimulating protein synthesis and promoting the proliferation and differentiation of muscle cells.
 
2. Enhanced recovery: It is believed that IGF-1 LR3 may aid in the recovery process by facilitating tissue repair and reducing the time required for healing after injuries or intense physical activity.
 
3. Improved insulin sensitivity: IGF-1 LR3 may have a positive impact on insulin sensitivity, potentially leading to better glucose utilization and metabolic regulation.
 
4. Potential neuroprotective effects: Some studies suggest that IGF-1 LR3 may have neuroprotective properties, promoting the survival and growth of neurons and potentially offering benefits in conditions related to neurodegeneration.
