I think that 13 weeks is too long for your first run with it. And I would run Tren A like some of the other bros said in case you get the nasty side effects. Tren is amazing, but it is potent stuff. I had the night sweats really bad and of all the different sauce I have ran, Tren was the only one that shortened my fuse as well. I was strong as hell, but mean too. I have been out of the game for a couple years and I am just getting ready to jump back in. I have ran numerous cycles at this point but Tren won't be part of them for a while.
