I am currently on only my 6th day of tren A@75mg/ED and prop.@100mg/ED...do either one of these ever cause anyone to get tightness or stiffness in their back ?? (mainly lower back I guess) and i have woken up the past few nights with cotton mouth, but I drink AlOT of water throughout the day, and usually a big glass right before I go to bed...any info would be appreciated, thanks.
