This is a very stong drug with a good list of cons and a handful of pros. I tried it twice, mostly out of curiosity, to see if it would be worth adding to my prep. In the end, I felt torn. It is good for quickly altering the physique, but injectable tren is already a staple of my prep. I feel that although the gains aren't as instant from injectable, running it longer will allow for even more changes than the quick changes you get from OT. At the end of the prep, I'll stick with tren and use halo as my oral. Combining steriods is more powerful than using one on it's own. 

A situation that I could see oral tren being worth it is on the last 3 wks of a prep that doesn't contain injectable tren. The "gains" you get from OT are going to be increased strength, better seperation, vascularity, and hardness. Most of these things are not going to be kept long term. 

The main thing i Dislike about oral tren is that newbies, who only want to do orals, think that it's going to be the best cycle for them because its so strong. They couldn't be more wrong. For the experienced user, who is looking to try something novel, it can be an intersting experiment, but I think it's far from the best steroid.
