Giving my input since I'm still 100% male at the moment and not on any blockers or replacement hormones...I hope this is well-received.
I suffer from the occasional testosterone spike. Increased thirst is definitely among the...interesting...effects the increase in T can produce. You may also find yourself irritable, unusually aggressive, or fatigued. Now, those could be from the fact that I'm getting extra on top of what my body produces, but I don't have any way to make a comparison to anyone.
