If we are talking about over the counter products I would say no. I mean I can't say they don't work at all but the benefit you are going to get even the strongest ones is going to be so small that those products are really not worth investing your money.
I like Cardarine because if will help you do more cardio and at a higher pace. It works to increase your v02 max. Diet is still how you can make the biggest impact though.
Clenbuterol works great for me, especially if I've hit a plateau and fat loss stagnates. I use it 2 weeks on/off. I've also made some progress with orlistat, in the past. It keeps you from absorbing fats that you eat.
Gw would be the best option and about myself without fat burner I did burn lots of fat and it's only possible through diet but I don't say fat burner are useless, use it if you need that all
