Sounds like things are going good.
As far as the afternoon energy fall off, well as good as TRT may be there is bad news....you're still human.
My point, I've been taking gear now in some capacity for 15 years, 4-5 of it TRT, the rest bodybuilding doses. Regardless of the methods, doses, combinations of drugs, etc. basic facts of life do not change, i.e., at certain points of the day you're a little more tired than others, sometimes your hornier than other times for no reason other than you are, sometimes you're a little more hungry at times despite everything being the same...that's just life.
