Absolutely. This touches on a point made by
@luki7788 recently in another thread - saturation of aromatase, in a massive guy like luki simply with greater body surface area/volume of aromatase, the dosage where saturation is reached is higher than in most even with lower adipose tissue %. Aromatase may be saturated in a guy like luki somewhere, arbitrarily, upwards of 3g of test, whereas in a smaller guy, it might be closer to 2. Still, I believe my point stands, that by aromatizing to weaker estrone (this is still aromatization, simply not to the very potent estradiol), you have greater net androgen activity in the face of weaker aromatic products. I do have a hypothesis that sort of unifies the anecdotes of primo, bold, mast, acting as anti-Es, but cannot rule out some metabolites acting analogously to exemestane as AIs, this is a possibility with some metabolites and again, would require 3D modeling/docking to prove or disprove.
