100mg per weeks is a fairly common starting dose. Doses normally maintain in the 100-200mg per week in most TRT plans. Does this hold true for everyone? No, some need a little more and some actually skyrocket on even less but the 100-200mg range is fairly common. In most cases, if that range of dose isn't working for you, you have something else going on in your body that needs attention unrelated to TRT. Also, keep in mind when you're talking about a testosterone dose, that may not be all of your TRT plan as that does not include the need or use of items like HCG, anastrozole, or other possible medications.

I do not understand your last question.
