IGF-1LR3

Intended Use:
IGF-1 LR3 is intended for research purposes only. Reconstitution with bacteriostatic water (BAC water) is required before use.

Storage:
Store lyophilized powder in a cool, dry place away from light. After reconstitution, keep refrigerated at 2–8°C.

Solubility:
Reconstitute with BAC water. Gently swirl to dissolve—do not shake.

Vial Size:
Lyophilized multi-dose vial (commonly supports up to 3ml reconstitution).

Shelf Life:
Lyophilized: up to 24 months
Reconstituted: recommended use within 4–6 weeks

 

Handling:
Use sterile techniques to maintain product stability and integrity.

Muscle Growth and Hypertrophy Studies
Research indicates that IGF-1 LR3 promotes muscle cell proliferation and hypertrophy, supporting lean tissue development in preclinical models.

Enhanced Protein Synthesis
Studies show increased protein synthesis and nutrient uptake in muscle cells, contributing to anabolic processes.

Cellular Repair and Recovery
IGF-1 LR3 has been associated with improved tissue repair and regeneration following stress or damage.

 

Extended Activity Models
Due to its modified structure, IGF-1 LR3 demonstrates a longer half-life compared to native IGF-1, allowing sustained biological activity.

IGF-1 LR3 works by directly activating the IGF-1 receptor, bypassing upstream signaling:

  • Stimulates muscle cell proliferation
    → increases muscle growth potential
  • Enhances protein synthesis
    → supports anabolic processes
  • Improves nutrient uptake
    → increases efficiency of muscle cells
  • Extended half-life
    → provides prolonged activity compared to standard IGF-1

 

Overall Effect:
→ Direct anabolic signaling
→ Strong growth and recovery support
