I' ve NEVER heard of taking adrenaline supplements....sounds interesting though....
You mis-interpreted the parts of the text that talked about adrenaline.
It' s not mentioning or promotion supplementation of adrenaline, but discussing how the MAX-OT style of training stimulates the adrenal areas (so you can push that heavy weight).
I checked, there is no mention of adrenaline supplements, just the mention that this type of training will stimulate and stress the adrenal system.
