Yes and no for the points you make. Thank you fir your time reading through my off the top of my head and struggle for diction spiller et spill.
Speaking three languages can cause issues as you may understand it can become difficult to accurately convey an article of observation.
Most users of aas would indicate the use of testosterone as a base compound in a cycle, for the clear benefits of its metabolites seen from the aromatase and 5 alpha reductase pathways (to name just two) . So therefore when testosterone is dosed along with other non aromatising aas AND boldenone you will see competition for aromatase enzyme by boldenone and the resultant metabolites (of which being biologically inactive), in effect, blocking the binding of biologically active estrogens (derived from testosterone) to the the alpha and beta ER. Estrogenic activity is reduced via this observed physiological mechanism.
I have observed this in monogastric model studies using porcine subjects, investgating fcrs (feed conversation ratios) in conjunction with selected (common to foreign meat industry) aas, with PGh (Porcine growth hormone) and with PGh an insulin.
A key observation made was that the affinity at which boldenone competed for the aromatase enzyme (pCYP19A1) in the catalyzing estrogen synthesis process, was on an individual to individual basis. Genetics being a likely source for this divergence in data trends.
