HCG will mimic LH and allow endogenous test production regardless of exogenous androgens. However once u discontinue the HCG atrophy will happen again. Using HCG post cycle is risky, because the endogenous test boost itself could be inhibitory. HCG is best used in spurts throughout a cycle to periodically reverse testicular atrophy. In an 8 week cycle it is not necessary because u arent shutdown for that long, however if u must use it, try using 500iu ED weeks 3-4 and 6-7. Good Luck.
