The .25 eod mantra is a generalization but normally it's sufficient for most people.
If you need .5 to 1mg daily on a 500 mg cycle it is unique to you. We all can aromatize at differing rates and some may need more, some less. You must simply be at an accelerated rate. I assume this is backed up by BW and not simply how you feel.
Not many people on a TRT protocol maintaining physiological levels tend to need .25 eod. If so their protocol and dose timing should be reexamined.
