i took scherings at 300mg week it did squash my libido a bit thats how i know they where real, primo is a great steroid for those who already have healthy positive peiece of mind and a good attitute and dont wanna risk all the mental side effects from gear. winny/test/eq ect ect can really fuck with your head if and send you into a nasty depression and the like.....primo/winny is a great stack
