Yes,as long as it's in the vicinity of the arreola,then it is probable that it's the onset of gyno.Some people are hyper-sensitive to tren,most are not.I have a theory that tren influences prolactin levels,and if an individual has an ample amount of receptors to take this up,they become activated and wham-gyno...I believe that most of the progestin-based steroids have this capability,deca,anadrol,and nilevar as well.Might be a smart idea as fonz suggested to add in some bromocryptine and chasteberry to combat prolactin,as well as winny to de-activate progesterone receptors...
