Hey Jay,
Weird, I would have thought T would help. Maybe it is helping you put on muscle which will help you burn fat. But muscle is heavy, you may not loose much actual weight.
My wife has used a range of things, but not too much success. For real results I think the prescription stuff is better e.g. xenical. You could talk to the doc about it.
Perhaps you could examine your eating more, work at your proportions, reduce fats - eat lots more veges, and some lean proteins (size of your palm is one portion), avoid prepackaged food. Cook with a non-stick pan, eat more wholegrain, cut out junk food, takeaways, chips, and fizzy drinks, get some low energy snacks. Use light milk. If you are using more energy than you are putting in then you will loose weight. Sounds easy but it can be fricking hard to change eating habits..
Or you could join something like weight watchers and use their point system - it works when you follow it. My wife lost lots of weight that way but he had to really change the way we cooked.
Best of luck!
