DEFINITELY take caber with the deca....or prami if you can handle the sides. And about the nolva....i still believe nolva is what cause my prolactin issues after a tren cycle. Thats why if i do a cycle including deca im not going to use nolva, just aromasin and caber all through my cycle and pct. Everyone is different though. Some say nolva is a no no with deca or tren, others say it doesn't matter.
Running deca and adding nolvadex at any point is going to cause serious issues with up regulating progesterone and once off it could still leave you open to a nasty estrogen rebound. I'm not a fan of nolva in any case but definitely would never run it with deca. Bad idea my friend. Look into forma stanzol for deca cycle. I've used it and it worked phenomenally. The only time I would consider nolva is as a last resort. That my opinion tho. I'm not saying it Hasent been done. But I've heard some real horror stories too
