As a diabetic type 1 I am fully depending on my insuline injections. Since I take 3 capsules of Rockstar a day I have noticed that my blood sugar stays better and longer. I inject now one time a day and need less insuline. I didn’t had that with other cordyceps products I have bought via the internet. Crazy!! As mechanic I need to be fit and sharp at my work, this was a huge help to me.
