I think that there is too much emphasis om testosterone, not only here, but also in the general population. Many seem to think that testosterone is some kind of power hormone, but it's actually the weakest, and does the least. DHT is our main culprit, DHT is also responsible for the growth of our reproductive system, balding, etc. Yes, DHT is produced from T, but DHT is ten times more powerful in expression, which means that with a tiny, tiny, tiny bit of T, DHT can unleash havoc. But, DHT is also independently produced in the skin, adrenal gland, prostate and there are probably more organs involved which are yet to be correlated, since no-one actually knows for sure. Cortisol is involved as well, especially with terminal hairs and sebum production.
Since no-one knows for sure which hormones are exactly involved, they prescribe us an anti-androgen: a medication that prevents all androgens from expressing/attaching. Kinda like a hail-shot. So if you want to know, then you have to find out what works for you. Takes a lot of time I guess, lot of blood tests, elimination of foods, etc. It probably would pay of to try a large range of anti-androgens, and see what they do. And don't forget the simple DHT blockers, sometimes that's enough. For others they don't work. Bicalutamide is worth a try.
