You're sailing on a sea of rumour & worry, RH. Who said you must never use Nolva with
Tren? Small amounts won't do you any harm, but neither will they do any good to protect you from sore nips & lactation with
Tren (though Nolva will protect & help alleviate progesterone gyno from
Test). The word you're looking for is
Dostinex (aka
cabergoline), which will protect you from the excess
prolactin you may get from
Tren. For me the best protection from progesterone is small amounts of
Arimidex EOD, which should not cut into your gains very much and should also help you avoid excess water weight.
Having said that, you ought not use either Nolva, Adex, or
Dostinex unless you detect a need for them.
