halo0073 Posted July 30, 2015 Share Posted July 30, 2015 This study is pretty amazing. It backs up everything I have known to be true about A1 for years. Especially important is the confirmation that it has a negative impact on mood for men. So many of my guy friends have known this for years due to testing but it hasn't been scientifically proven until now. Link to comment Share on other sites More sharing options...
