I don’t know about the T receptor thing. A huge influx of test compared to baseline is going to case a lot of other things to happen though, then the body tries normalizing more and you figure it out from there. I know what you’re saying would be true of test’s affect on dopamine levels, which is partly why if you’re trying to lower your dose like I am now to test some things out, you can go through a period where you’re more depressed but it will typically normalize as long as you’re not under dosing with the new dose. Test also causes some people’s thyroid to go up to keep up with it, and if your thyroid’s already having trouble keeping up that can also be an issue.
Pretty much any of the major hormones like test or thyroid or cortisol or growth hormone all impact one another. A lot of the honeymoon period’s probably tied more to the rest of your body’s resources not having down regulated yet.
Not that you can’t have better periods than the honeymoon period. If I’m on the right T3 and T4 and test, I actually feel better than I had in the honeymoon period, or potentially ever, sans losing penile sensation, which is a big downside.
I think TRT’s actually best suited for people that don’t need it. Which isn’t to say plenty of people don’t do wonderfully on it. But the people that do the best are usually ones where everything’s working fine anyway and their body just upregulates everything. People with holes in their bucket health wise usually have things drain out faster and potentially develop bigger holes.
