Natural IGF-1 is quickly captured by IGF-binding proteins, which limits its availability in cell culture. IGF-1 LR3 swaps glutamic acid for arginine at position 3 and adds a short N-terminal extension, which sharply reduces that binding and extends its activity. It is widely used as a supplement in cell-culture media and in growth-signalling research.
LR3 analogues are standard growth supplements for mammalian cell lines because they stay active longer than native IGF-1.
Used to study PI3K/Akt and MAPK pathways downstream of the IGF-1 receptor.
Honest caveat: the findings above come from published laboratory and preclinical research, or from clinical studies of the compound class. They describe what has been studied, not what this product will do.

Store the lyophilized powder at −20 °C long term or 2–8 °C short term, protected from light and moisture. After reconstitution with bacteriostatic water, keep refrigerated and avoid repeated freeze-thaw cycles.
Tap a question to reveal the answer.
Long R3: the long N-terminal extension plus arginine (R) at position 3.
It binds IGF-binding proteins far less, so it stays available and active longer in culture.
TrueLabs ships IGF-1 LR3 from inside Canada with tracking, usually in 2-4 business days, with a batch-specific third-party COA and no customs.
