yeah, a broken one helps give a kick. over 500 is the iffy level and over a 1000 is bad. Mg wise. I have taken a lot over 500 and around 600 I start to feel weird I think. The focus on your job is awesome. Makes it all clear energy. Hard to explain. Super coffee. Just eat em. Swallow em or chew. No need to go farther. You dont want to. Also over 300 you get a bad feeling in your stomach, but it will go away as soon as the trammie wears off. Lots of stuff online.
