Hi ATB
That’s saliva (4 times a day), so I freeze them as soon as collected then post the next day.
The blood test only gives you a measurement for that point in time, which might be fine when you take it in the morning, then drop too much in the afternoon and then rise too much in the evening. Or totally the opposite of that! Everyone is different.
Yes ATB, it’s a quite a journey getting it right. Mine was pretty perfect in February then after getting covid in May my cortisol plummeted yet again.
