In my hypothetical experience I have ran Tren many times and I swear by it. I don't even run cycles without it anymore. That being said, I've heard so many negative comments about it that its kinda pissing me off. Today I had a jack ass at work tell me I was basically killing myself by using it, he has done a couple cycles and thinks he is an authority. I've had people say similar things throughout the years and its all rubish. People on this board seem to be a little older and wiser than others so I don't see much bullshit info on here, but a quick Google search of "trenbolone cycle" will take you to many other boards with endless comments on the dangers of tren.
