IGF-1
Native insulin-like growth factor studied for muscle, tissue signalling, and cellular-proliferation research.
IGF-1 (Insulin-like Growth Factor-1) is the growth-factor peptide at the centre of muscle, recovery, and tissue-signalling research. It is the natural messenger the body produces after growth hormone does its work, carrying that signal into cells to drive proliferation and repair. This is the native form — distinct from the longer-acting LR3 analogue — studied for satellite-cell activation and anabolic signalling in research models.
As a foundational growth-factor tool, native IGF-1 lets researchers study the downstream signal directly rather than the hormone that triggers it.
