Drop test dose way down and up your Deca dose. You should experience much less sides this way. I would also switch Prami to Caber. Dosing frequency depends on individual response, so it's up to how easily you get Prolactin sides from 19nors. Though Deca takes time to build up, so keeping that in mind it shouldn't be necessary to run Caber/Prami from beginning unless you are prone to Prolactin sides. Keeping Estrogen under control right from the start will help to avoid raising Prolactin and causing problems.
Personally I've never had to use Caber when on Deca, just keep it on hand when running it.
