hello today starts week 15 of my 16 week cycle, last year i did my first cycle at 12 weeks of test e and eq 500mg/400mgs per week. this cycle im doing test e and eq 750mgs/600mgs per week. i started this cycle with with 4 weeks of prop at 100mg eod. anyways heres my problem, my sex drive was great for the first couple months, about a month ago it plummited (<---not sure if i spelled that right). ive kinda lost all drive to go to the gym also. i wasnt taking any nolva until a few weeks ago. i started taking 60mgs for 4 days, then 40 for 4 days, and then 20 ed. when i was taking 60 my sex drive seemed to come back a bit but now im down to 20 mgs ed and its gone again. can i keep taking nolva at 60 mgs ed? what should i do.
