the advantage to trenbolone, nandrolone and testosterone is that they are all still legit products and you stand a much greater chance of obtaining them via script (with the exception of course of trenbolone) legally, or i should say via "script", of course if you have access to a highly reputable ug source that is no concern. As i've said before my only anecdotal experience is with metheneolone and a bit of testosterone hydrocinnamate but johnnyboy knows what he is saying from a biomedical standpoint, there is no interference there and that is a very synergistic stack at the cellular level and with reasonable test dosage feminizing effects would be minimal. primo should be taken orally for best results as it is minimally dangerous to the liver (does not need dealkylation). masteron would make a good antiestrogen as little as it is needed. I listen to what he has to say regarding dosage, unless you are a mouse or a rat i can't tell you much there lol
