Highly unlikely as you are injecting EOD using smaller doses of testosterone. Larger doses injected less frequently would result in more aromatization and ones overall testosterone levels plays a role as increasing t will result in increasing ones e2.
What is your weekly testosterone dose and your total t/free t levels on your current protocol?
If your e2 is high (sensitive assay) and you are experiencing symptoms than you may need to look into the use of an a.i. or possibly lower your weekly testosterone dose to reduce e2.
