You will need to be concerned about estrogen control while taking test. Test converts to estrogen. The solution is to use an AI, like adex. If you are using 500mg of test, .5mg adex every other day should be enough. GH does not effect estrogen levels. For some, it can increase sensitivity to prolactin. If estrogen is under control, this should not be an issue. In fact, this should not be an issue for most people anyway. If you find that you are still getting some sensitivity, you can increase the adex to 1mg EOD or even more if needed. If there is still an issue, you can try caber at .5g 2x wk.
