I have used tren many times. I did several cycles before I touched it. And when I did I made the best gains I have ever made. Hard, dry muscle. My diet wasn't precontest good but it wasn't bad. I was stacking it with test enth. I don't understand why one would eat like shit while on a cycle but there are lots of dumbasses out there. If your friend made such great gains eating shitty think about what would have been possilbe if he ate clean. Also, note that just like any other aas I have used, tren made the biggest differnece the first time I used it. I ran 50mg/day, now precontest I run 100mg/day. Some say that is high, and it is, but my body handles it well. I would not reccomend taking over 50mg/day for the first time. It is a harsh drug. Also, I would not take it for a first cycle, I would say one should have a few cycles under their belt before touching it. Some people have a very hard time with it.
