Many people think that because tren and masterone dont convert to estrogen because they are not androgens that they wont cause you gynocamastia and that is %100 false anytime you have a hormone spike or drop your at risk of throwing your hormone balance off the body compensates with producing estrogen.. It can happen.. Its a different process than androgen converting to estrogen.. Unfortunately you dont know when this might happen.. I know a few bodybuilders who got gyno from tren A and i had a problem with gyno from tren A also.. All i was using at the time was tren A and deca.. So there are many things that can trigger high estrogen levels.. Medications such as most antidepressants cause gynocomastia and they have no androgen or hormones in them but they can still trigger something that causes a hormone imbalance/low natural test levels and the body compensates with releasing estrogen.
to answer your question Nolvadex, arimadex, femara or aromasin are all good choices just dont ignore the problem if you have swelling or soreness start an anti estrogen rite away.. I personally find 1-2mg of femara (letrozole) taken before bedtime works best for me.
