Agreed with what @Fleezy and @slesh have said. A "good" diet and more sleep is not going to provide some massive increase to his T levels. Sure, cleaning up his diet, getting consistent with lifting/exercising and getting into shape is going to greatly help him feel better, but not because it's jacking his Test up hundreds of points.
While some may think having to inject Test each week is a "big deal", in my opinion the bigger deal is living with Test levels that are below the low end of the normal range. *Note - I'm not saying it's something to take lightly; certainly plenty of thought and consideration should be given, hopefully alongside lots of conversation with a competent TRT provider. And if actial injections may be an issue he could also consider something like Androgel or Enclomiphene. My doctor has a lot of clients on one or the other (they don't want injections for one reason or another) and has said once things get dialed in with dosing and such, they do great. Those options tend to be more expensive, though.
My n=1 and regarding GH: I started TRT at 27. In addition to a stout dose of Test straight outta' the gate I was also prescribed 2.5 IU GH that I did 5 on, 2 off. What did I notice specifically from the GH? To be honest, not much of anything that I can recall. I stayed on it for around 7 months, during which I put on quite a bit of weight and started experiencing gains in the gym that I hadn't felt in a long time prior to that (late teens/early 20's were spent with a small amount of dabbling with injectable AAS but much more pro-hormones/designer steroids that were available at the time). I certainly think that the 250mg dose of Test I was taking was responsible for the majority of positive changes I was getting, as that took my test levels from extremely low to the high end of the normal range. Anyways, the GH was a pretty big additional expense to me at the time and I couldn't justify staying on it. Further, when I DID cease the GH, I don't recall feeling any different (positive, negative, or otherwise) than when I was on it.
But to sum up my TRT experience and from having started at a relatively young age, it's been overwhelmingly positive. It was warranted and I've never regretted going on it when I did.
