Foundational Research in Diet-Induced Obese Mice The frequently repeated weight and fat findings originate from a short mouse proof-of-concept study
Its a popular choice because the muscle is substantial, and the area typically has fewer nerve endings, which can mean less discomfort during the injection
Its also possible to feel no obvious sensation at the time of injection, apart from maybe a warmth if given IV
