I gave it 5 stars by NOT considering taste.The first time,it was vile.But I felt better than usual the next day.2nd time,still tasted like the bottom of a lawn mower.Felt awesome the next day.3rd time added MIO water drops,tasted tolerable.Still feeling pretty darn good.Now I know what to add and I HIGHLY recommend this product.5 gram scoop is all you need.
