I still don't understand people taking so many supps to lower cortisol. I mean it must work, enough people have gotten results from it that you'd have to say that. But even with the knowledge that too much can lead to fat stores and a host of other problems, you still need to have enough in your system. And especially if cutting, your thyroid function is going to depend A LOT on having adequate supply of cortisol in your system. If you lower your cortisol too much, it's going to shut your thyroid down and you won't be losing any weight my friend.
So if you are cutting, and taking something to boost your thyroid output, it would seem taking a cort reducer would be counter intuitive to what you are trying to accomplish.
