Herbs are designed to do certain things but what you are asking they wont do that.
Many pro-hormones wont aromatize so excessive estrogen should not be an issue unless, the pro-hormone has a rebounding effect with estrogen.
Many pro-hormones tend to inhibit estrogen, and when the cycle is done, you end up with low androgen levels yet due to the estrogen being inhibited the receptor sites are sensitive to estrogen.
Once the prohormone leaves the body you can get some form of estrogen rebounding where the receptor sites respond to estrogen.
Problem with prohormones is many of the new stuff nobody knows what sides they give, recovery can be a problem.
Do not argue with an idiot, he will drag you down to his level and beat you with experiance.
