We know at the TRT forum that guys need anastrozole 1mg per 100mg T ester and that is expected as a competitive drug. Does the binding aromasin need to be proportionate too? Yes, as the doses are quite small and we are trying to modulate T-->E2, not kill it.
FT-->E2 aromatization rates are proportional to FT levels, so some T dose proportionality is expected.
I can't provide much guidance for Aromasin in the context of cycling gear. But you definitely need more AI. Given the half-life, it may take 5-6 days of a constant dose to reach final serum levels. Suggest front loading 3x, 2x 1x dose over first three days.
Always best to manage E2 than trying to hide with a SERM.
