During??? never... why would you even consider clomid during your cycle? that makes less than no sense... you need to use a normal AI on cycle, not nolva... aromasin at 12.5 mg eod
what does your pct look like? what ancillaries are you using on cycle?
Clomid isn't an AI, and there's no need to ever run it on cycle. If you need to control estrogen, get yourself some Aromasin which is a real aromatose inhibitor
