The Insulin-Like Growth Factor-1 Long R3 or IGF-1 LR3 is a man-made form of Insulin-like growth factor-1 (IGF-1) that has been engineered to enhance its biological effect and minimize interaction with insulin-like growth factor binding proteins (IGFBPs). The properties of IGF-1 LR3 have made it an important tool for research studies on various aspects of cell and tissue growth, metabolism, and hormonal regulation in experimental laboratory settings.
Investigators have used IGF-1 LR3 in preclinical and in vitro research to investigate IGF-1 receptor activation, intracellular signalling pathways, muscle biology, protein synthesis, glucose metabolism, cellular proliferation, tissue regeneration, differentiation, and other growth factor-regulated biological events. Laboratory research has looked at biological pathways such as PI3K/AKT, MAPK, and mTOR pathways to help researchers gain insight into the effects of IGF-1 on biological processes. Nevertheless, the present knowledge base is confined to preclinical and laboratory experiments only.
In contrast to therapeutic drugs, IGF-1 LR3 from PeptidesX is for research purposes alone. It is not approved for human or veterinary use. Each batch comes with a certificate of analysis that includes identification, purity data, and other analysis information specific to each batch. Researchers need to check the Certificate of Analysis that accompanies each batch before conducting their experiments.
All IGF-1 LR3 from PeptidesX are for research purpose only and should not be used in humans and animals.

IGF-1 LR3 is an analogue of insulin-like growth factor-1 which is specifically synthesised for laboratory research involving cellular signaling, growth factor research, metabolism and tissue physiology.
IGF-1 LR3 consists of structural changes which have increased its biological activity and have decreased its binding affinity to the insulin-like growth factor binding proteins (IGFBPs). With such structure, the prolonged IGF-1 receptor signaling can be studied in laboratory animals.
Yes. The purchase of IGF-1 LR3 is available at PeptidesX for the use of legitimate laboratory research within the UK. The compound is supplied solely for research purposes and not for human or veterinary use.

Every batch is independently analysed and comes with batch-specific information. It is important that researchers check the Certificate of Analysis prior to experiment.
Researchers study IGF-1 LR3 for gaining knowledge about IGF-1 receptor activation, signaling pathways, cellular growth, protein synthesis, tissue regeneration and metabolism regulation.
Most research efforts use laboratory models to study topics such as skeletal muscle biology, glucose metabolism, PI3K/AKT signaling, MAPK pathways, mTOR activation, tissue development, cellular differentiation, and growth factor signaling.
IGF-1 LR3 comes as a lyophilised research peptide meant for use in the laboratory setting. Specifications, purity details, and batch information are all found on the corresponding product page.
Investigators are advised to store the product in accordance with the guidelines specified in the label and certificate of analysis. This means storing the product in appropriate laboratory settings away from extreme heat, moisture, direct sunlight, and temperature variations.
Previous preclinical experiments showed activation of IGF-1 receptor signaling pathways and subsequent intracellular pathways linked with cell growth and metabolism. But the data came from laboratory and animal experiments, and cannot be seen as proof of efficacy or safety in humans.
Yes. Investigators conduct research on IGF-1 LR3 in relation to growth factor signaling, endocrinology, skeletal muscle biology, glucose metabolism, tissue regeneration, and cellular development.
No. IGF-1 LR3 is an experimental research peptide that is not considered a drug, dietary supplement, or treatment for any disease at PeptidesX.
No. PeptidesX only provides IGF-1 LR3 for laboratory research purpose only. Results obtained from cell culture studies or experiments done on animals cannot serve to determine the safety and effectiveness of a product or its suitability for human consumption.
