Yeah although everyone is different, but for some reason I essentially am attributing the Eq to why my E2 is low when on a 500 Test C/ 700 EQ run. Can’t find official publications, but anecdotally from reviewing others blood work and general blogs, EQ appears to counteract the ability to convert test to E2, and it may actually aromatize to estrone or possibly a different derivative. Im dropping EQ after current cycle and replacing it with NPP/TPP blend for a late fall run (keeping test dosage the same but including proviron). Still getting great gains but can tell that my low E2 is causing some undesired affects with libido and may also be partially hindering my lean muscle increase. Going to get some bloodwork done soon to check my final weeks on before starting my PCT.
