1. There is no mechanism in the body that converts E to T. However, different glands in the body may see the increase in estrogen, or lack of testosterone, in the blood as a signal that more T is needed. It will then pump out more testosterone.
2. From what I've read, sublingual administration gives you a high blood level but it diminishes rapidly. Taking it orally is gives more stable of a level. I take it sublingually.
3. Since testosterone in genetic males is normally higher right after waking up (reason for morning erections), I would think it's better to take it when you wake up. I take my doses 12 hours apart, so I end up taking them around 10am and 10pm.
4. I've read that phytoestrogenic foods (such as soy) actually compete with the estrogen you'll be taking, so it's best to NOT consume phytoestrogens.
5. I'm sure healthy is always better.. however I eat almost nothing but protein and trashy food and ... quite honestly, I think I've progressed pretty well!
