Progesterone as a protective hormone:

The idea is that as a male you use incredibly small dosages 2-6 mg a day for a short period because it can lower estrogen and cortisol (inhibits the estrogen receptors and binds estrogen and destroys the enzyme that releases estrogen), giving the body rest and being able to increase androgens.

If you use too much you can experience estrogenic effects. Thing with hormones is the dosage makes the effect and decides the pathways.
