Hey Flask, no problem answering the additional questions.
a) I am serious. The Endo about fell over when she saw those levels. Whats unusual to me, is that to my knowledge dessicated liver is an antagonist against estrogen, and doesn't directly raise your T levels (I could be wrong, but thats from my research so far). I agree about the iron thing, however there are two forms of iron. Heme and Non-Heme. Non-Heme you can overdose on. Heme, you cannot (feel free to google this). Believe it or not, with low hormones at a younger age, chances are you are low on Zinc (white dots on nails are a good indicator of that), Iron or Vitamin D.
Personally, I had Iron Deficiency Anemia years ago, doctor's couldn't understand it and I know it was coming back, but the liver stopped it. (synthetic iron is crap).
Remember, dessicated liver is just liver. The same stuff you would eat. Just, in a pill.
b) Endocrinologist is the full name. They are responsible for checking Pituitary, Thyroid, Adrenals. Depending on the Endo, will depend on your results. Endo's don't do more specialist bloodwork really (sometimes they check more levels) but they tend to do CT Scans, MRI's, and other labratory testing to look for any causes (such as cancer). Mine is still unresolved, and they haven't found a cause. They were more concerned about someone in their 20's, who could still be in puberty being horribly low on T. My internal medicine (general doctor) saw my levels at 200 - 300 and said they were fine. I fought her, but she noticed something was wrong when I lost all control of emotions that same day in her office.
I'd get mad, then start crying. No energy. Nothing. She called a week later, told me to go an Endo and a Urologist. Urologist office said go to the Endo first, not them. My Endo wants me in the high 800 range for being a "healthy young male". Most Endo's who deal with sports medicine will br more likely to ensure your T is optimal (600 - 800) and not just "in range".
As a second notion to that, my body's natural T (according to bloodwork when I was much younger) was found to be in the 1,200 range. So my current "general" doctor wants to make sure I stay in that range.
I actually was getting a reaction from the 10g of testim, so I'm glad I was brought down and the dessicated took over.
The best suggestion I can tell you is tell the doctor you want to be in optimal condition. If the dessicated liver helps you out, use it to reduce your dependence on HRT. Don't take "no" for an answer though from any doctor. And don't be afraid to throw the "book of symptoms" at a doctor to make them understand.
c) My levels were at 270/ng before they started me on testim. At 5g I moved up to 340/ng if I remember correctly. at 10g I moved up to just under/over 500/ng, which was still not optimal. At the time the Endo was going off of "Until you have to shave every 2 - 3 days, we're going to keep raising you".
Based on that, the Dessicated Liver more than likely raised me (with 6 tablets) at about 1000/ng. While at the same time, handling my Iron, Zinc, and B all in one pill.
In terms of long-term side effects of a high T level, it honestly depends on your body. I know that when I had a reaction, I was excessively oily, skittish, hyper, and had trouble thinking. I'll call my doc tomorrow to see on my last test if I'm still high, as that would confirm whether that was "high T response" or "allergic response", which I think is the latter.
If your regarding long-term side effects of HRT, the problem is there isn't any research in it. Most people on HRT live for maybe 20 years then die, but that's because the age at which they obtain HRT. So there's not much info on that side, but for being on HRT for I think 6 months now, no roid rage, no shrunken testicles, no uber hairyness (well anymore than genetics created) and such.
My body is not back to normal yet unfortunately, but it was a step in the right direction. Low T can cause a lot of other things to go wrong, much like the thyroid can. As a twist in life, the Thyroid can cause low T levels as well or an overactive adrenal system (fight or flight response).
I'll be sure to update once I hear back from my doctor, but I'd love to hear what happens with yours, the cause, and if they get you back on the right track.
