You should be staying on TRT. It is for life so you don't come off. All that receptor stuff is nonsense. Just people trying to overthink and complicate things. I would also be taking the RAD and Nutrobal daily. You do not need a PCT at all. Whoever recommended clomid missed the fact you are on...
Lol, you are good man. We have plenty of "older" guys here, including me. Bitcoin is actually so incredibly easy to use. It is just because you haven't done it yet. I use coinbase personally.
