Quote From a Book
"Exogenous Hormones. Exogenous hormones come into the body from outside and can cause a world of problems.(Anabolic steroids, insulin, and the growth hormone injections described above, are examples of exogenous hormones.). The problems with exogenous hormones stem from the fact that your body cannot control them - it cannot make the hormone jump back into the needle or pill bottle. All your body can do to counteract the incoming hormone is decrease of shut-off internal (endogenous) production of that particular hormone. (These natual counterregulatory mechanisms are called feedback loops). If there is still too much hormone floating around after exogenous hormone is administered, it cannot precisely mimic the subtle ebb and flow of naturally produced hormones. The human body is exquisitely sensitive to hormonal fluctuations. As long as your body is in control, as with finely tuned control mechanisms; and you can upset your entire endocrine system, with potentially grave consequences.
If you take the hormone for a long enough period of time, then once you stop taking it, your body does not resume making the hormone. (Remember "use it or lose it?" - well, at this point you lost it.) When that happens, you are hooked for life on taking the hormone(a very profitable situation for the dealer of the steroids, growth hormone, etc.). Even if you do not completely lose the capacity to produce hormone, it takes a while to come back. And until it does, you suffer a shortage of that hormone, during which time all of the positive effects are reversed - just ask any ex-steroid user. As you can see, exogenous hormones are risky and have an effect opposite to Natural Hormonal Enhancement, by impairing, rather than enhancing, natural production of hormones.
Endogenous Hormones. These are the natural hormones produced by the body. Unless you have an endocrine infirmity(like diabetes, hypogonadism, Cushing's disease or Addison's disease), your hormones can never rise too high or fall too low because your body regulates hormones in the same way a thermostat regulates temperature - it allows fluctuations within a set range. You can naturally enhance endogenous hormones from "low-normal" to "high-normal," but never above normal. You influence endogenous hormones every day of your life."
Ok thats from a great book I own called "Natural Hormonal Enhancement" by Rob Faigin. It is an excellent book I have read it cover to cover many times. I have never actually followed his plan but follow a similar one. Its a great book anyway. That was a pain in the ass, I have to go find the book and find that specific page and type it all in!. I hope you guys enjoyed it!. Anyway I hope this is ok, it is just a quote and I did give credit to the author!.
Lawhammer keep in mind that the body is the most sophisticated machine ever created. Everything does something for a reason. My guess is they ran blood on hundreds of men and saw the trend that Test in the system is between this range to this range. Your body regulates test for a lot of good reasons some stated above. Remember your body is always trying to reach a state of homeostasis so if your on HRT with levels that your body was not meant to have there will be a reaction. When supplementing anything that your body makes we want to work with it not against it or else it defeats the whole purpose.
