What Is the Difference Between IGF-1 LR3 and MGF?
IGF-1 LR3 Pack 1mg
The IGF-1 gene can be spliced into more than one protein product; IGF-1Ea is the systemic, liver-produced form that circulates in the bloodstream and is the basis for both native IGF-1 and the IGF-1 LR3 analog, while IGF-1Ec (MGF) is expressed locally in tissues, including skeletal muscle, and has a distinct C-terminal peptide sequence not shared with IGF-1Ea.
Because MGF is produced locally rather than circulating systemically like IGF-1, published research has generally studied it as a locally-acting signal associated with tissue response to mechanical loading, a different research question from the systemic IGF-1 receptor signaling that IGF-1 LR3 is used to study. Synthetic MGF fragments used in research are themselves separate laboratory constructs from IGF-1 LR3, despite both deriving conceptually from the same parent gene.
Neither IGF-1 LR3 nor MGF is an approved human therapeutic, and neither is part of REVIVE LAB UAE's catalog. This comparison is general research information only and includes no dosing, administration, or protocol guidance for either compound.
