What is IGF-1 LR3?
IGF-1 LR3 is a modified analogue of insulin-like growth factor 1. The LR3 designation identifies structural changes relative to IGF-1.
Long-[Arg3]IGF-I is another way to write IGF-1 LR3. Long refers to a 13-amino-acid extension at the N-terminus, and Arg3 to arginine replacing glutamate at position 3 of the original IGF-I sequence.
The complete LR3 designation distinguishes the substance from other IGF-1 variants. Retain the full name when comparing a catalog product with the molecule described in a research paper.

Why LR3 belongs in the name
An extension and an amino-acid substitution change molecular structure. A search result for IGF-1 alone may therefore describe something other than the LR3 variant.
The variant quantity is a pack specification. It does not describe the length of the extension, a measured activity or a solution concentration.
