Hi all, I am making this post in relation to an issue I am having with my sex drive after hopping on 500mg test cyp, up from 250 in my last blast. (5' 11, 250 lb, 20% BF, Male) So 500mg, split into two weekly injections. I began taking a quarter of a mg Arimidex every other day, which I thought was conservative (too much, too little?) The main problem I have been having is just no desire really for sex, soldier's not as responsive, which started about when I hopped on to this cycle, in the past however I had a great sex drive on just 250mg test and no AI. I am not currently experiencing gyno and it's been 2 wks on. Do you guys think this is estrogen related, if so, high or low? Any constructive input welcome.
