No, that is not following my line of thinking at all.Explain to me how achieving a 1000 point jump in test levels within 5 days is expected. By yours and OP's logic, steroids users who come off a steroid into PCT should react that way, quite the opposite.
The title of this thread is fasting causes low T BTW.
Again, the adaptive process of fasting may increase sensitivity to AR resulting in higher androgen levels immediately after refeeding. This is a short term effect, and I see no reason to believe that a 180% increase in T for a few days after this event is going to be sustained or effect AR density long term. The body is simply responding to nourishment and upregulating androgen receptors accordingly in an attempt to seek homeostasis, assuming the stressor (starvation) is no longer an issue.
I do not see the usefulness in the study that you posted unless there are several consecutive blood tests for at least a couple months after the fast.
