Tweetyea i read that and i have to tell you that i disagree first hand i have had gyno since my first cycle ever. i have always used nolva with great succes and when its all said and done have nothing left after my cycle is over and im done taking the nolva. however last spring i used tren and got some gyno started nolva to no results on the gyno however i got lucky and once i ended the tren the gyno slowly went away. now i have been on test for some time now and started to get gyno used some nolva and it shrivled back up added npp to my cycle and low and behold there is gyno showing up again im still on nolva and even at a pretty high dose and it's not helping to me thaat means that there is a completely different kind of gyno that comes from tren/npp/deca than what comes from test/dbol/etc. whether you want to deam it progesterone gyno or something else there is still a difference
