Plus you don't want to kill cortisol levels. It may even be beneficial to have high/normal range on cycle:
There is synergy between the two hormones involved in GH synthesis.

"RESULTS: ...cortisol...in the presence of thyroid hormone, increased the growth hormone synthesis rate an additional 2- to 5-fold"
"DISCUSSION: ...The synergistic control of growth hormone synthesis by T3 and cortisol appears to occur independently of one hormone modulating the cellular distribution or concentration of the receptor for the other hormone (12). Because thyroid and glucocorticoid hormones appear to act at the nuclear level, it seems likely that both hormonal receptors act at the genome in a concerted fashion to increase the accumulation of GHmRNA.
...suggests that both hormones interact to modulate the growth hormone response by a pretranslational mechanism, presumably at the level of the growth hormone genome.

ABSTRACT We have previously demonstrated that thyroid hormone controls growth hormone synthesis in GH1 cells and that the induction of the growth hormone response by glucocorticoid appears to be highly dependent on thyroid hormone action. Thyroid hormone induces growth hormone synthesis approximately 5- to 20-fold and cortisol increases this response 2- to 6-fold further. Long-term kinetics of the growth hormone response show that, without added thyroid hormone, cortisol can induce a small-growth hormone response after 48 hr of incubation....
