Purity tested
An outside lab measures it and reports the exact number.
Identity confirmed
A second test proves it is what the label says.
Report published
Signed, filed by lot number, and public before the vial ships.
Researchers study IGF-1 LR3 as acting through three broad routes.
It is studied as a ligand at the IGF-1 receptor, the same target as the native growth factor.
The substitutions are studied for lowering affinity to IGF binding proteins, raising the free fraction in culture.
Cell work examines the PI3K/Akt and MAPK cascades downstream of receptor engagement.
