hey been lifting for 4 years competing for 2 done 5 - 7 cycles 21 yrs old male 5'7 165-170 lbs

k heres the deal
was on tren prop winny for 12 weeks started with a .5ml of prop and tren for 4 weeks then bumped it to a ml a day, winny at 50 mg a day orals. did it no problems everything went amazing.
right after i finished that, i took proviron also for the last 4 weeks of the cycle also
i went right into another cycle of sust and eq with a tab of arimidex every second day, want to take .5 a day and not have to chop the pills.

the problem is today after training i couldnt get my junk to work with the girl, and we go at it everyday and it has only happened once before on the tren prop cycle. any ideas what could have caused this malfunction?

i ate 600 cals for brkfast at 800
500 cal at 1000
500 cal at 1245
shake and a ricecake for 350 pwo at 330
i didnt eat a post workout meal, but i went and grabbed the girl and came to my pad, and it wouldnt work.
would it be because i was in a calorie deprived state after my workout or something else?

thanks for any input, and if i forgot to state anything let me know. thanks
