Great thread dp - that's an amazing setup you have for a home gym. You obviously know your stuff. I started out training wanting to be a power lifter but my friends talked me into entering a bodybuilding contest since I was naturally cut. Did very well and entered four more after that. I still train and wanted to know more about your supplement list. I take a few of the ones you listed but was curious if you could elaborate or tell which ones are must haves - I'm a few years older than you.
I haven't gone into protein/BCAA, but for the longevity stuff:
CoQ10
EPA
ALCAR
ALA
Keto DHEA
Astragalus
Resveratrol
multi
I buy CoQ10 powder (sourced from Japan (Kaneka)) and add to coconut oil. I melt 14oz of coconut oil on low heat in a sauce pan. Once it's liquid I add the oil back into the jar and add 60g of CoQ10 powder. It's approx 1g per tsp. I take 1-2 tsp per day. The plasma conc. cannot be achieved with any other preparation.
I used to consult with IFBB guys. One of whom placed 5th in the Olympia.
