Description
GF-1 LR3 (Insulin-like Growth Factor 1 Long Arg3) is a synthetic version of human IGF-1, a hormone that shares structural similarities with insulin. It is essential for growth, muscle development, and cellular repair. The “LR3” variant features a 13-amino-acid extension and an arginine substitution at position 3. These alterations extend its half-life to approximately 20–30 hours and decrease its interaction with IGF-binding proteins (IGFBPs), enhancing its bioavailability.
Clinical research on native IGF-1 (e.g., J Clin Endocrinol Metab, 1996) reveals anabolic and metabolic benefits, such as increased lean body mass and enhanced insulin sensitivity.
USAGE AND STORAGE
IGF-1 Lr3 is provided as a lyophilized solid to guarantee maximum stability and facilitate ease of use in research settings. For best results, keep it away from direct sunlight and store it at a temperature between 2-8 C° both prior to and following reconstitution. We suggest using Bacteriostatic mixing water for the reconstitution process. Additionally, make sure that both the peptide and the mixing solution are at room temperature during reconstitution to avoid temperature shock and to assist in proper dilution.
SYNTHESIS AND QUALITY ASSURANCE
This peptide is carefully synthesized using a regulated process that guarantees high purity, rendering it appropriate for sophisticated scientific research. Our dedication to quality ensures that every batch is subjected to rigorous quality control.
