What Is IGF-1 LR3 Peptide?

We supply IGF-1 LR3 Peptide as a laboratory-grade research compound for pre-clinical and in vitro study settings. IGF-1 LR3 Peptide is an extended half-life analogue of IGF-1. Researchers apply it in laboratory and in vitro research settings. We manufacture it to a defined synthesis standard. Importantly, we restrict distribution to qualified researchers and laboratory personnel.

Research Applications

IGF-1 LR3 carries an amino-acid substitution at the B-chain N-terminus along with an extended sequence. Early research linked these modifications to reduced binding to IGF-binding proteins and an extended research half-life relative to native IGF-1.

Interest in growth factor research continues to grow within pre-clinical literature. Here, this compound serves as one of several reference materials researchers use to study relevant signalling pathways. Consistency of starting material supports reproducible results, though it forms only one part of a wider experimental design. Researchers should therefore standardise handling procedures alongside sourcing to minimise variability between runs.

Purity, Testing & Quality Assurance

Every production run undergoes independent purity and identity testing, most commonly by HPLC or mass spectrometry, and we provide a Certificate of Analysis on request. This gives laboratories a way to confirm specification before use, which matters most when a study’s findings need replication elsewhere. We keep full batch documentation on file for traceability.

Storage & Reconstitution

This compound ships in lyophilised form. Researchers should reconstitute it just before use with a suitable solvent, such as bacteriostatic water. After reconstitution, the solution loses stability more quickly at room temperature, so we recommend refrigeration and use within a short window. Reconstituting only what a single experiment needs helps avoid unnecessary freeze-thaw cycling, which can degrade peptide integrity over repeated cycles. The unopened, lyophilised form remains more stable when researchers follow the storage conditions on its COA.

Usage Restrictions

This product serves laboratory and in vitro research only. It is not a medicine, and researchers must not use it for human consumption, animal consumption, diagnosis, or therapy. For independent chemical reference data, researchers can consult the PubChem compound database.
