not a whole lot of options out there, unless youre just looking for something like Glucorell/Sesapure etc to help prevent gaining fat when taking in a good amount of calories. But most fat burning aids geek you out to a certain extent.
Best ive found for losing weight is good old fashioned cardio. About 20 mins a day works well for me. I hate feeling all tweeked out. Thats why I dont mess with Clen much or any other aids out there really.
