yes EQ has anti estrogen properties through an enzymatic process. this process takes time to build up.. but the longer your on EQ the more anti estrogenic effects you get.
however depending on your goals you may not want or desire these anti estrogen effects (as estrogen in the presence of elevated androgens is extremely anabolic, increases IGF production, HGH output, and hepatic HDL production). its kinda hard to put on muscle when your E levels are low. sometimes adding a compound like Dbol or Ment just to get additional estrogen conversion can be beneficial to a cycle,, let alone thinking of taking an AI and hindering estrogen from the start.
its all person and context dependent. theres a time and a place to keep estrogen in the normal range. theres a time and a place to let it skyrocket and enhance muscle growth. it really depends on the situation .
but AI's are not generally "needed" by any means . and in fact some people will go so far as to say they are dangerous and unhealthy and should't even be part of a TRT protocol let alone a cycle (I personally still see a use for them in various situations).

even if your estrogen sensitive and prone to gyno . theres a whole heck of a lot of ways to run AAS with no need for an AI .. as 80% of the steroids available for us to use don't even convert to estrogen in the fist place, and as previously stated some of them are anti estrogenic .
its generally only the "test only cycles " crowd that see a need for AI's . but for guys that run mainly anabolics, AI's are never generally needed.
