Google came up with nothing using your spelling. I see MetaSlim which near as I can tell is supposed to raise your body temperature to burn calories.
You can do the same thing with capsules of Cayenne pepper. The only drawback to this is if you have problems with heartburn / stomach burn. It will raise your body temp and burn calories and 60 capsules will cost about $2. Or you can buy pre-made from someplace like GNC for about $10. The GNC version will have other "special ingredients" but the real working one is the pepper.
the other answer is to write down everything you eat and the number of calories. Look up you calorie burn rate through any number of sites that have calculators and set your diet to be 500-1000 calories short of your burn rate.
Add exercises to increase muscle size and you will be burning the weight as safe as it can be done.
