Introduction: Recombinant human IGF1 (rhIGF1) improves insulin sensitivity and glycaemic control when administered to people with diabetes. The effects of rhIGF1 on lipid metabolism in vivo are unclear.Objectives: To determine the effects of rhIGF1/rhIGFBP3 administration on fasting lipids, non-esterified fatty acids (NEFA) and glucose homeostasis in recreational athletes. This study was part of a randomised, double-blind, placebo-controlled trial...

Introduction: GH is widely abused by athletes for its anabolic and lipolytic properties. As the tests for detecting GH abuse develop further, it is possible that athletes will exploit IGF1 as an alternative or additional doping agent. There is currently no evidence to suggest that IGF1 administration improves athletic performance.Objectives: To determine the effects of rhIGF1/rhIGFBP3 administration on body composition and physical fitness in recreationa...
