if your already pinning eod for the prop then honestly this is a killer setup. most guys think mast is only for cutting but i swear it keeps the moon face away when you push the test up to 500 and just makes you feel like an absolute unit in the gym. plus that shbg drop is real so you'll probably get way more out of that test than you would solo. just watch your hair if your prone to thinning because mast is a straight up vacuum for the hairline but otherwise its a super clean way to bulk without looking like a bloated water balloon lol do it.
