What IGF-1 LR3 is

IGF-1 LR3 (Long R3 IGF-1) is a modified analog of insulin-like growth factor 1 with a longer half-life in laboratory conditions. It is supplied as an analytical-grade reference material for laboratory research.

What the research has examined

IGF-1 and its analogs are studied in cell-growth, signaling, and cell-culture research contexts.

Listing an area of study is not a claim about any product or outcome. These references are provided so qualified researchers can locate the primary literature. All materials are supplied for laboratory research use only.
