hydroxycut hardcore Pro series?

Hey everyone :love: I'm a crossfit athlete and im very trim around the stomach but i still carry weight and alot of muscle mass on my legs. I've reduced crossfit to once or twice a week and have been doing long distance running 12 to 17kms etc for my workouts but my body shape just wont change. My weight has completely stopped dropping :( I'm about 8 kg off where i would really like to be. I have been told hydroxycut can really help to kickstart more weightloss? any oppinions out there? please serious answers only, i dont need people telling me supplements, thermogenics, preworkouts etc are bad.
