Can I buy IGF-1 LR3 in Canada for research?
Yes. TrueCanPeptides supplies IGF-1 LR3 as a research compound for qualified laboratory use, shipped domestically across Canada. Not for human administration.
What is the difference between IGF-1 and IGF-1 LR3?
Native IGF-1 has a half-life of approximately 10 minutes due to rapid IGFBP binding. IGF-1 LR3 incorporates an arginine substitution at position 3 and an N-terminal extension that reduces IGFBP binding affinity, extending its half-life to approximately 20–30 hours — making it a more practical research tool for in vitro and in vivo studies.
What purity is your IGF-1 LR3?
≥98% by HPLC with mass spectrometry identity confirmation. Batch COA available on request — sales@truecanpeptides.com.
