Yeah, the fatigue gets a little rough, but that will improve as your body naturally seeks homeostasis.
You might also notice some achy joints, brittle nails & hair, and of course the libido decline. Guys don't realize just how important estrogen is to the body. It effects so many critical areas of our well being, even with the immune system. Please ensure that you take plenty of vitamins during this period, especially plenty of C, D-3, B12, plus some calcium, and don't be skipping meals.
Also, you are correct, DHT is converted downstream from testosterone when it's introduced (or interacts) with the 5A-reductase enzyme. The HPTA regulates natural test production by signalling the testicles with LH. This process works through a negative feedback loop with the HPTA and the testicles.
