IGF-1 LR3
IGF-1 LR3 is a long-acting analog of insulin-like growth factor 1, and it features an extended N-terminal sequence of 13 additional amino acids along with an Arg3 substitution. Together, these modifications reduce the peptide’s affinity for binding proteins and extend its bioactive half-life. As a result, researchers frequently select IGF-1 LR3 when they study cell proliferation, muscle tissue growth, and insulin receptor signaling in laboratory settings.

Research Applications
Researchers commonly use IGF-1 LR3 to examine cellular growth mechanisms, protein synthesis pathways, and IGF-1 receptor (IGF-1R) binding dynamics. For instance, scientists studying muscle regeneration, cellular hypertrophy, and growth factor signaling often cite this peptide across published research. Furthermore, because IGF-1 LR3 binds less readily to IGF-binding proteins, it remains bioactive for longer periods, which makes it a useful tool in both in-vitro and in-vivo experimental models. Consequently, many laboratories include it in comparative growth factor studies alongside native IGF-1.
Why Buy in USA & Europe
We produce our IGF-1 LR3 under strict GMP certification and verify it through independent third-party testing to confirm ≥98% purity via HPLC analysis. In addition, every order ships with a Certificate of Analysis (COA) that documents molecular weight, amino acid sequence, and purity data. We also provide cold-chain shipping, with delivery times of 1–3 business days within the USA and 2–5 business days across Europe, and we maintain full compliance with regional research-chemical regulations throughout both markets.
Frequently Asked Questions
What is IGF-1 LR3 used for in research?
Researchers use IGF-1 LR3 to study cell proliferation, muscle tissue growth, and insulin receptor signaling pathways. We supply it strictly for laboratory and research purposes.
How should IGF-1 LR3 be stored?
Store IGF-1 LR3 as lyophilized powder in a freezer at -20°C prior to reconstitution. Once reconstituted, keep it refrigerated and use it promptly to maintain stability.
Is IGF-1 LR3 legal to purchase in the USA and Europe?
Researchers can legally purchase IGF-1 LR3 in both the USA and Europe when they buy from compliant suppliers. However, neither the FDA nor the EMA has approved this product for human consumption.
