If I was forced to go OTC, I would grab:
(1) A comprehensive PCT product -- PCT Advanced / PCT Assist / PCT Revolution / etc
(2) DAA or potentially an additional test booster -- Pure Test / Diesel Test / Free Test / Test Drive / etc
(3) An AI for estrogen management
(4) An anti-cortisol product (optional)
I'm sure someone else will add more name/compound specific products, but the above is where I would start if I didn't have a SERM.
