steroids and stimulants stress the body-thus stressing the adrenals. Everyone has a theory. My own is that adrenal fatigue/chronic fatigue are caused by physical/emtotional/mental stress. The way out is to calm the sympathetic nervous system, which, is in chronic overdrive in adrenal fatigue. Once the sympathetic system is calmed, the body/adrenals can heal properly by building adrenal reserves-naturally, and often without the help of ten million supplements! BUT that is just my theory!
