as rick pointed out, a misuse or non use of test with tren can cause this problem too... this is what we are all talking about when we stress the importance of knowing tren inside and out before you begn the cycle... there are so many more things to be aware of and concerned of with tren use as opposed to many other anabolics... all steroids are to be taken seriously, but tren takes that statement to another level... tren commands respect or basically, it will straight fuck you up...
