Both Lipo Ultra and Ab-Solved are known as the best transdermal products for site specific fat loss. Period. The proof is in the feedback which you can find on a lot of boards and the relative to other transdermal products. So no, I'm not just talking out of my behind. But please do your homework and don't jsut rely on what I say.
That said, they are not miracle supps. You need to have your diet in check and be training and doing cardio. To put it very basically...they don't melt the fat off you. More or less, they help loosen up all the fat in the applied area, but YOU then have to get rid of it with ur cardio and training.
Ab-Solved is aimed at those around 12%BF, whilst Lipo-Ultra is for those around 10%.
Good luck.
