I prefer to use more test than tren to avoid issues with the tren. And keep in mind that if you control estrogen, progesterone and prolactin will be more likely to be kept in check. If you were to notice any sensitivity, you can certainly increase your adex from .5mg to 1mg EOD. Even 1mg ED if needed. You could get the caber to have on hand if you need it but theres a good chance you don’t so theres no sense in taking something if you don't need to. If you are finding that you can use caber, .5mg 2x wk should be enough as long as you are using real tabs like the ones Naps has (not research chems).
