Im comuns to The end of 75mg ed tren ace and sides were very tolerable. Changes I notice are slightly more agitated or irritated about small little problems or inconveniences during the day, nothing I can't easily handle tho. My hair has fallen out more from tren than anything else. The biggest down I have from tren is that it messes with my lungs, I can't walk up 5 stairs before I'm short of breath and I get tren cough so bad everyone and then I almost pass out from it. Other than that it is fu@$n awesome stuff. Will be using it often from here on out. The pros definantly out weigh the cons. Just my two cents.
