Metabolic
IGF-1 (Insulin-like Growth Factor 1)
IGF-1 is produced primarily by the liver in response to growth hormone (GH). It mediates most of GH's anabolic effects on muscle, bone, and tissue repair.
Optimal levels support recovery and body composition. Very high levels are associated with increased cancer risk.
What It Measures
Concentration of IGF-1, reflecting growth hormone activity.
