I'm having a hard time understanding why non-aromatizing compounds like tren and winstrol produce such harsh sides when coming off. If most of the androgens aren't capable of converting to estrogen, what's the problem? I've been reading up on tren and it's around 5x as receptive as test and it doesn't aromatize. Sounds like a miracle drug to me, but everyone tells noobs to stay away. Why is this?
