Many thanks for the 6 tubs of Herbalife Formula 1 shake. I take it not for slimming or anything like that, I take it more to try and gain weight and drink it after two of my three meals a day. I suffer from ankylosing spondylitis (arthritis on the spine, neck and hips), and one of the symptoms is lack of appetite..very true. I need to make sure even though I don't have much of an appetite for meals, I know for sure drinking the Herbalife is at least getting the vitamins and protein into my body that I need. Love the taste of the chocolate Formula One, and makes me eat a meal, knowing I'll be having the shake right after it!! Great fast shipping..many thanks. RAY LANG.
