Where to Buy IGF-1 LR3 in the UK
IGF-1 LR3, the Long Arg3 analogue of insulin-like growth factor 1, is valued in cell-growth signalling research for its extended half-life. Sourcing it well in the UK rests on independent purity data and a cold chain kept on home soil. This guide explains what IGF-1 LR3 is, what to check, and where Peptura fits.

What is IGF-1 LR3?
IGF-1 LR3 is an 83-amino-acid analogue of recombinant human insulin-like growth factor 1, carrying an N-terminal extension and an arginine-for-glutamic-acid substitution at position 3. Together those changes lower its affinity for IGF binding proteins, which lengthens its biological half-life relative to native IGF-1. Research has examined its part 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.
