Let me try to summarize:
If you are new(ish) to serious weight training, then you are going to make progress no matter what.
If you eat healthfully, you will make even better progress.
Supplements are very good at two things, primarily: supplementing your diet with nutrients that might be missing from your food (example: take a decent multi-vitamin), or to bring about specific hormonal changes (examples: Biotest's M to reduce the effects of estrogen in the body, Alpha Male or RED KAT to increase lagging testosterone levels, HOT-ROX to promote lipolysis).
But if you are eating right (and there's no reason you shouldn't), then you're getting decent nutrients. If you are still fairly young (and I think 29 is on the edge there), you may not need a T-booster.
What I'm trying to get across is simple: try food and exercise--and use the knowledge you find on this site--BEFORE you start putting money into the "extras."
Check out the "Are You a Beginner" and "Are You a Beginner II" threads started by vroom. They are your first steps. The rest can wait.
Good luck. Keep us posted.
