IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a modified, longer-lasting version of the body’s natural IGF-1. Its extended half-life and stronger biological activity make it one of the most powerful growth factors used in research. IGF-1 LR3 is studied for its potential to drive muscle growth, accelerate recovery, and support tissue and cellular repair.

Key information and effects

  • Enhanced muscle growth: IGF-1 LR3 can stimulate muscle cell proliferation and differentiation, potentially supporting increased lean muscle mass.
  • Improved recovery: It may accelerate repair of muscle fibers, tendons, and connective tissues after training or injury.
  • Increased protein synthesis: By activating pathways involved in muscle building, IGF-1 LR3 may enhance anabolic processes.
  • Fat metabolism support: Some research suggests it can influence nutrient partitioning, potentially aiding fat reduction while supporting muscle retention.
  • Cellular repair: IGF-1 plays a role in tissue regeneration, nerve support, and overall cell growth.

Reconstitution

Reconstitution is the laboratory process of dissolving a lyophilized (freeze-dried) research compound in a suitable solvent, most commonly bacteriostatic water, to prepare a solution for research use.

Use our Peptide Reconstitution Calculator to work out the solvent volume and concentration for your research parameters.

Storage

Lyophilized research peptides are generally most stable when stored frozen (around -20 °C), sealed, and protected from light and humidity. Refer to the Certificate of Analysis and product documentation for any compound-specific handling notes.

Once reconstituted, stability and handling vary by compound. Consult the peer-reviewed literature specific to the material you are working with. Minimise repeated freeze-thaw cycles to preserve sample integrity.
