I recently asked for information on how to obtail a adrenal stress test. Many people answered for which I am very grateful. Blue Horizon was recommened. I noted that one of the responders was. Blue Horizon Medicals, who offered a £30 discount with code THYCOR. I have just ordered the test, but no where could I add code for discount. Also, their site is so confusing, I don't know if they will be sending free containers for saliva or if they think I want blood tests. Also, I have no clue if VAT has been added; what cost has been billed or why, one of my responders only paid £85 for the same test bearing in mind a £30 reduction from £129 does not equall £85. Feeling a bit stressed by this. Good for the old adrenals, eh?
