Where to Buy IGF-1 LR3 in the UK
IGF-1 LR3 (Long Arg3) is an extended-half-life analogue of insulin-like growth factor 1, widely used in cell-growth signalling research. UK researchers sourcing IGF-1 LR3 should look for verifiable third-party purity data and reliable UK cold-chain handling. This guide explains what IGF-1 LR3 is, what to check when sourcing it in the UK, and where you can buy independently lab-tested IGF-1 LR3 from UK Peptide Lab.
What is IGF-1 LR3?
IGF-1 LR3 is an 83-amino-acid analogue of recombinant human insulin-like growth factor 1, modified with an N-terminal extension and an arginine-for-glutamic-acid substitution at position 3. These modifications reduce binding to IGF binding proteins, extending its biological half-life relative to native IGF-1. Research has examined its role in cell growth signalling and IGF-1 receptor activation. IGF-1 LR3 is supplied as a lyophilised powder for in-vitro laboratory research only, not for human or veterinary use.
Published research on IGF-1 LR3 is indexed on PubMed.
