Anabolics are not the solution to your problem.
Your solution lies within your diet and training program.
I think nearly everyone will agree on here that 3-4 hours daily is excessive. Most efficient training programs will have you in and out in anywhere from 45 minutes to an hour and a half.
I would suggest you post your diet as well. The "losing fat" portion of your post would make me think that perhaps you're severely under-eating...when I was a fatty way back and first started training, I certainly had a caloric intake that was way too low and, paradoxically enough, it severely hindered my weight loss.
Diet + training program, post it up. But I'm telling you now that anabolics ("I've been working out a year, I'm thinking about Tren") are not what you want to fix your problems. Anabolics are meant for those that have their diets and training nailed in and know what they expect from a cycle, and I don't think you have either of those two fields down yet.
