If you’re going to run low dose test until your next cycle and want to add something to your “bridge” until your next cycle, you could add either frankly.
I personally would add Proviron at 50 mgs (25 am - 25 pm).
Mast is an option too, but if only run off I needed the AI properties, as it’s more expensive and has some hair shedding issues (assuming you have your hair). Mast is better at sculpting and is a relatively weak androgen.
Proviron will help with your free test and sex drive and is a relatively safe drug for a bridge.
