As a fitness professional I would never reccommend thermogenics to anyone as they can be very dangerous. they can cause many problems including dehydration, down regulation of thyroid hormones, insomnia, heart palpitations etc. But if your going to use a thermogenic the best way and safest way is to indeed cycle it. There are many different cycles that you can use, im most fond of use it for 1 week and then get the heck off of it! Trust me this aint a good supplement to abuse I know a few people who have abused this and one is now taking medication for her hypothyroidism, and another is going to his physician tommorow due to irregular heartbeat most likely due to the hydroxycut. If it is ephedrine based there have been many reported deaths due to its use! My final statement is just: BE CAREFUL!
