I have understood your point mate. Thanks a ton for your advice. Actually I finished a 12 week cycle of test eq and some mast ,Winny thrown at the end. I used HCG throughout cycle (300-350iu twice per week) till 2 weeks after last test shot. Then I did clomid + nolvadex for 3 weeks . Now it has been 1 month after finishing PCT but my libido is still not what it was like before cycle. I can get an erection . Testis are also full in size . But libido is not the same. So I was thinking may be HCG has caused some damage but as you cleared my doubt that HCG is not the culprit. Then what could be the issue according to you ? Also, there is no sign of estrogen bloat , gyno . so estrogen is normal.
