haha yea "tren cough", "metallic taste" rofl and "nightsweats" are pretty common too, amongst the internet beasts. 
Only thing I noticed from tren was extreme hornyness. Yes, only ONCE i had some "tren cough" but it was due to a bad injection.
no bro sience... just my experience...
i get very edgy when on tren... very very...
i can get it under control, but when making important decissions in my life, i will not use tren...
the cough is due to the ester.... the acetate ester... get the same cough with test acetate...
and ofcourse hitting a vein and injecting in the bloodstream, always gives the cough...
