Your natty test is probably down but since you are inject 500 mg per week, your test is not technically down. I am not saying that you should or should not be "raging" horny, but it works different for all people. I will tell you this. My second cycle was exactly the same as yours and the EQ made my sex drive fall to almost nothing, but on the other hand, I am just finishing up a Test/Deca cycle that made me actually feel sorry for my wife...she just could not keep up with the sex drive at all. It was no problem for me to want it 7 or 8 times a day.
If you are OK with it then keep the #'s the same, but if you want to see which drug is reacting in which way...then lower the EQ a bit to see what happens. There is also another recent thread about "Overstimulation with Test" that you might want to look into...here is the link
