I disagree with the bold/underlined part because tren increases prolactin vs progesterone. Nolva is also an "antilactogen" as well as "anti estrogen" which prevents prolactin from attaching to the breast tissue.
*Edit - I guess I should explain a little further. Deca's effects have shown to increase progesterone more so than prolactin, while nolvas ability to upregulare the PR could or could not have a true effect on us, it also does not actually handle the issue of both progesterone AND estrogen. Since higher estrogen is going to further any negative reactions in the body with progest, then an AI would be better suited for this purpose vs a SERM.
So basically, to handle estrogen and progesterone problems, start with an AI. If you are lactating, throw in some Nolva to stop it as quickly as possible to allow caber/prami to do its job.
