This is the rason that I suggest test. Nothing is going to support libido like test, but other steroids will shut down your natural production. My suggestion is that you get ahold of some HCG now and start running about 500iu every 3-4 days, to force your body to produce as well as restore teste size. I would continue on this right up to the point that you start Clomid therapy for PCT
It also wouldn't hurt to throw in some Proviron during the remainder of your cycle to help with sexual function
