Diet Pill/Supplement to go along with work out and exercise

Ok here is my situation. I am 6’1 weigh 185 lbs. I have a cruise in 3 weeks and would like to shed some fat and get the muscle showing. By no means am I fat and I have been working out for around 2 months now but not to religiously. Recently this past week I have been working out about 5 days a week with weight lifting and running typically at the gym for 2.5 hours a day. Also I have a diet all planned out for the next 3 weeks to go along with the work out. My question is… are there any supplements or fat burn pills that you guys know of that would go along with the diet and exercise? I know a pill alone won’t do much but I figure combine the three and it should be a great combination.
