I have AAS experience on and off going back almost 20 years and I've pretty much tried it all but I just did Tren (along with Test E) for the first time over the winter and I won't do it again. I didn't even hit it very hard but the sides were too much. The insomnia/sweating (which I had a lot of) wasn't even the worst of it, I just felt all over the place emotionally, it built over the course of the cycle and I was pretty much a wreck by the end of it. I especially wouldn't recommend it if you live with someone (girlfriend, wife) and they aren't aware of what you're doing. I ran a complete PCT (the 6 step one that's most recommended on this board) and I'm still dealing with shut down issues which I contribute to the Tren. Last shot of Tren was in early January and I'm just now starting to feel like my libido is coming back, again not something the wife/girlfriend isn't going to take note of. Everyone is different, these are only my experiences with it, Tren just wasn't for me.
