As Steve says the last week is about fine tuning not drastic changes. If you are making drastic changes in order to look good then that is a tell tale sign you made big mistakes. An AI will control estrogen yes as long you use it correctly and in the right amounts. An AI prevents the conversion of testosterone to estrogen making a SERM redundant and unnecessary. What guys need to realize as well is you cannot just throw in an AI the last few weeks before a contest as it will not be effective against the already present estrogen.
