I got to give props to BigD for the Tren Ace I got from him. This was my first experience with Tren. Since I can't compare it to any other brand all I can do is speak on this one. The Tren Ace was very smooth. I had zero pip. My strength gains were great and I was able to lean out even more. I had a little insomnia for about two weeks but it got better. I also took a cheap sleeping pill from Walmart that worked well. I sweated a lot more than usual but this is also a common side of this stuff but it was no big deal. I never woke up with night sweats just sweated more in the gym. I had zero anger or aggression issues. In fact, I had a better sense of well being than ever. For the first two weeks, I pinned .75 EOD, but bumped it up after that to 1.25 EOD. I stacked this with sust at about 350 x 2 week.
