I would respectfully disagree. I personally would have to remove tren a from that list. It's amazing in many ways but if by piece of mind you mean grow horns and want to rip the gates of hell off the hinges then yes it's great. LOL ;-) I've ran tren a more many cycles and right now I'm on test cyp and from a piece of mind comparison I feel very good about everything. I wish I would have tried a test cyp cycle years ago instead of tren a just for a break from the tren "madness". Haha I am exaggerating of course.
