Factory direct sales high quality large quantity supply of IGF-1LR3 raw material 5mg 10mg 20mg

IGF-1 LR3 (Long Arg³ IGF-1, long-acting arginine³ insulin-like growth factor-1) is a highly active and long-lasting analog of IGF-1 that has been artificially modified. Its main functions are as follows:
1.Core biological function
- Strong muscle growth promotion (anabolic)
- Activates the PI3K/Akt/mTOR pathway, significantly enhancing protein synthesis.
- Activates muscle satellite cells (stem cells), promoting the generation of new muscle fibers (hyperplasia) and muscle fiber hypertrophy.
- Anti-catabolic: Reduces muscle protein breakdown, protecting muscle mass.
- Accelerates tissue repair and regeneration
- Promotes cell proliferation and collagen synthesis in bones, cartilage, tendons, and ligaments.
- Speeds up muscle damage repair after exercise, reduces soreness, and shortens recovery time.
- Metabolic regulation (insulin-like effect)
- Facilitates glucose uptake by muscle and fat cells, assisting in lowering blood sugar.
- Improves nutrient distribution: More calories are used for muscle growth, reducing fat accumulation.
- Strong anti-apoptotic and pro-cell survival
- Inhibits apoptosis signals, protecting neurons, cardiomyocytes, etc.
- In vitro activity can reach 2-3 times that of natural IGF-1 and about 200 times that of insulin.
2. Advantages over natural IGF-1
- Extremely long half-life: Natural IGF-1 lasts only a few minutes, while LR3 can last for 20 to 30 hours.
- Not easily inhibited by binding proteins (IGFBP): The affinity is reduced by more than 1,000 times, making its activity more stable.
- Stronger and longer-lasting effects.
3. Main Application Scenarios
- Research: Cell culture, serum-free medium, stem cell expansion.
- Sports/Fitness (non-medical abuse): Muscle building, local "spot growth", muscle retention during fat loss, accelerated recovery.
- Clinical potential: Muscle atrophy, fracture healing, neuroprotection, regenerative medicine (still under research).
