Burning fats

Have you ever tried to have active sport life doing only work outs and healthy food..??? Well i have tried n have to say- it works...but only for some months. I love food n love having dinners with friends, n have to admit it- love sweets as well :(.
For that reason i help my work outs using fat burnings- L- Carnitine. It is best, absolutely safe n effective amino-acid that helps metabolism works better n faster. I have taking it for a while now n im so in love with this product. All u need to do is to have a 12.5 ml 20-30 min before work out n then...just push :)))
Now i want to have faster result thats way i take also small serving from 9ml before i go to sleep. In this way my metabolism is working faster all night as well...

What u guys think about it...have u ever tried something like this?
