Im a newbie so sorry in advance for any improper etiquette. 5th week of 500 test e per week.(2×250 Sunday and Thursday). Not running an AI but have nolvadex on hand. Nipples became somewhat tender and hard all time so took some nolvadex and it went away.. Now im having an issue with libido perfomance.. Not desire . Just performance.Also iritability and aggression. Never had an issue with this before . Talked with some people and was told my E2 is probably way high. Getting bloods soon.. can i use nolva to bring it down. Im really wanting to finish cycle and kinda at a stand still. Do for a dose tomorrow .. any help would be appreciated
