hCG is not a PCT drug. It won't do shit for recovering the hypothalmus and pituitary.
Clomid will sometimes can visual disturbances and _very_ rarely, these problems can maybe be permenant. The probability of having permenant problems from nolvadex are even less. We're talking 1 in 10,000+.
If you aren't willing to take a SERM class drug for PCT, then you shouldn't be cycling AAS.
