falco, keep in mind that anytime you run something hormonal you might have a libido issue after the run is done. this is normal and does not mean anything is wrong. you have suppressed natty test function by introducing something into your body, now that the compound is gone you body realizes that you need more test and it will make, it just takes a little while. how long? well that depends on how suppressed it is and how quickly your body can make more, it's an individual thing. you'll be fine in no time
