IGF-1 LR3 (Insulin-like Growth Factor 1 Long Arg3) is a synthetic analog of human IGF-1 engineered to have a longer half-life and enhanced stability. The substitution of an arginine at position 3 and an extended peptide chain increases its biological activity and resistance to binding proteins. Researchers study IGF-1 LR3 for its potential role in cell growth, muscle regeneration, and tissue repair, as well as its involvement in glucose metabolism and protein synthesis within laboratory models.
This research peptide is verified for 99%+ purity. COA: IGF-1 LR3 (1mg)
Products from Elite Miami Peptides do not include usage instructions, as they are strictly for in vitro research and prohibited by law for human or animal use. Misuse or unlawful application will result in permanent denial of service.
Each vial contains exactly what’s indicated on the label. For instance, a 10mg vial contains precisely 10mg of lyophilized peptide. Researchers may divide it into smaller research portions—such as four 2.5mg aliquots—but the total content remains the same.
Yes. All peptides are supplied in lyophilized powder form and do not come reconstituted. Any extra materials required for research, such as solvents or diluents, must be obtained separately.
When stored as a dry powder, peptides remain stable for up to 2 years.
Once reconstituted, the solution should be kept refrigerated and is typically stable for up to 2 months under proper storage conditions.
IGF-1 LR3 is a long-acting growth factor analog that binds to IGF-1 receptors and activates signaling pathways related to cell proliferation, differentiation, and repair. It is often studied for its influence on myoblast activity, muscle tissue regeneration, and anabolic signaling in experimental models. Researchers have also explored its ability to modulate glucose uptake and cell survival mechanisms through the PI3K/Akt pathway — making it a valuable peptide for studying cellular metabolism and recovery.
IGF-1 LR3 is a longer-lasting version of the IGF-1 growth factor. Research looks at how it may support muscle growth, cell repair, and tissue regeneration. It’s also studied for its role in glucose uptake and cellular energy pathways.

Engineered analog of human IGF-1 designed with an Arg at position 3 and an N-terminal 13-aa extension to reduce IGFBP binding and prolong activity. Wikipedia
Length: 83 amino acids (vs. 70 in native IGF-1) Molecular Formula (reported): C₄₀₀H₆₂₅N₁₁₁O₁₁₅S₉ Molecular Weight (reported): ~9.1 kDa CAS: 143045-27-6. Wikipedia+1
IGF-1 LR3 has been studied across molecular and cellular biology fields for its effects on: Cellular: tissue regeneration, myoblast proliferation, and protein synthesis. Metabolic: glucose utilization and insulin signaling modulation. Molecular: activation of PI3K/Akt and MAPK pathways. Systemic: potential influence on tissue recovery and anabolic response. These findings indicate IGF-1 LR3’s importance as a model for understanding anabolic and regenerative processes in scientific research.
In simple terms, IGF-1 LR3 is a lab-engineered version of the body’s natural growth factor, made to last longer and work more effectively in research. Scientists use it to study how cells grow, repair, and use energy. While promising in lab settings, IGF-1 LR3 is not approved for human or animal use — it is strictly for controlled laboratory research.
