Read the 'protocol for injections sticky'. Do not post into the stickies! Do not hijack peoples topics. Always come back to a thread that is yours for lab results, updates and questions. Do not create multiple posts about your issues.
You will not find much here about PCT except for the few cases like yours. The steroid's PCT info is often flawed.
Your PCT has not worked. Your testes seemed to have been responsive to hCH but not clomid. A first glance, it appears that your hypothalamus and pituitary are not working parts of your HPTA.
PCT can fail if there is an estrogen rebound. Arimidex/anastrozole has an important role to play.
Using hCG and any SERM together is dead wrong. You can be over stimulating the LH receptors in your testes.
Nolvadex and clomid are doing the same thing. If you have doubts that the clomid might not be real, then switch back to nolvadex and see how that goes.
How long between the PCT and starting clomid? You may need lab work to deal with this.
It is normal and expected for the scrotum to pull up during sex.
What is your history with deca, hair loss drugs and pro-hormones?
