exertional migraines = BP issues from gear??? I smell a possible connection...or I'm just insane

have you always had this condition?
one month break is a long break...enough to terminate the cycle...which u should do...tren is pretty suppressive so at three weeks i would imagine some degree of shutdown
it would probably behoove you to do a simple nolvadex/clomid PCT for 4 weeks..since u have these compounds, it can't hurt to err on the safe side
Going back to my first point, if you want to try, go back to the gym after a week of discontinuing the gear and if you don't get a migraine, then it's probably related to the gear, which means next time you start, use ancillaries to control water retention and drink adequate water to lessen the viscosity of the blood
