I was thinking of doing the 4 test and sorry if this sounds silly but should one take no supplements for stress whilst doing this. I did a morning blood test and it was top of the range. I did this a while ago as I reacted badly to just 1/4 grain of NDT and it was suggested that could be due to adrenal problems. I am taking holy basil night and morning, ashwagandha at lunch time also rhodiola drops (in the morning but have forgotten today ummm). Thanks.
