IGF-1 LR3

It is an elongated and modified version of the human insulin-like growth factor 1 (IGF-1) peptide, designed with an arginine substitution to resist rapid breakdown in experimental models.

It is studied for its significant biological effects on cellular hyperplasia, anabolic signalling pathways, and tissue regeneration.

The LR3 modification prevents the peptide from binding strongly to IGF-binding proteins, significantly extending its half-life and biological activity in experimental models compared to standard IGF-1.

No. IGF-1 LR3 is supplied strictly as a reference compound for in vitro laboratory research. It is not for human or veterinary consumption.

Yes. IGF-1 LR3 is not a controlled drug under the Misuse of Drugs Act 1971 and is entirely legal to buy, possess, and utilise as a laboratory reference material.

Yes. All batches of IGF-1 LR3 are tested by independent, third-party laboratories using HPLC to ensure >99% purity.

IGF-1 LR3 has specific molecular identifiers including its Chemical Formula, Molecular Weight, and CAS Number. These exact specifications are detailed in the Specifications table above.

IGF-1 LR3 is supplied in a sealed glass vial as a lyophilised (freeze-dried) powder. For laboratory research, it requires reconstitution with a compatible solvent such as bacteriostatic water.

Store the lyophilised IGF-1 LR3 powder at -20°C (or in a standard freezer) away from light. Once reconstituted, store the solution at 2-8°C (in a refrigerator) and use within the timeframe appropriate for your protocol.

Yes. Every batch of IGF-1 LR3 is associated with a Certificate of Analysis confirming its exact purity and identity.

IGF-1 LR3 is available to buy from specialist UK suppliers like KYRO Labs. We provide strict >99% purity, third-party tested reference materials for laboratory and in vitro research.
