There is nothing you can do with 2X per day usage to significantly minimize downregulation of natural test -- androgen levels are too high. As for bringing it back quickly with OTC products, Vitex may work (this is the active in Biotest's "M" product that is coming out) -- I haven't looked at the literature a great deal -- basically their are some good things and not good things, but until I have had a chance to look at it closely, I can't give a worthwhile opinion. There is nothing else that i am aware of that is any good. if chrysin did not inhibit 17-beta-HSD activity, a topical version of it would be a good choice.
