Not a problem at all, bro. I've tried both deca and tren. Deca made me stronger and gave me a lot of join relief (which helped the strength). Made me a bit bloofy, though. Tren is awesome - I've run 100 mg ED and the conditioning/strength it brings are really mindblowing. The only side effects I got were a marked increase in aggression and insomnia.
The aggression is what made me stop tren for a while - I was pissing off everyone I know, lol. If you can handle it, though, go for it.
