You may be able to get away with that. .25mg eod is already on the lower end, but if it's been working for you at that dose, you may be able to back off a little when you add the Epi.
I will be running "The 1" weeks 12-16 of my Test cycle, it is also anti-estrogenic, and was planning to run Adex at .5mg E3D once I add it.
