I THINK I ran Deca last year.... lol. It was supposed to be Tren, but all the sides and effects seemed much more like what I read about Deca. And when I ran Tren early this year, and it was definitely tren, it was a much different experience.
Strength gains were awesome, and I looked pretty great. Sexual sides were shitty. But overall I felt really good, and didn't feel like a crazy person the way tren sometimes makes you feel. But again, I wouldn't choose Deca over just doing more test, in most cases.
