I didn't think tren aromatize? Isn't it a dht based compound?
its a 19 nor like deca/npp so u can get progesterone sides which are enhanced even worse if estro is high. mainly puffy nips some guys get from tren, then if estro is high look out gyno. My bad if I worded that wrong, I meant controlling estro in the cycle, not controlling estro from the tren.
imo you have two choices:
high test, low tren
or
high tren, low test
otherwise for most sides are harsh and ruin ur sleep and life lol
in my case I gain more muscle from almost everything other than test, and test I get a lot of sides past 500mg/wk so I prefer to keep it low
