actually i dont think there is anything 'unhealthy" about taking that product.. its caffiene, synephrine, gugglesterones, some yohimbe and oleic and linoleic acid. i would worry only about the gugglesterones, ...there have been some studies that show they bind to androgen recpetors and lower the amount of free- t you have..
other than that, the lipo 6 should be very good, especially since you are in ketosis.. it should clear out your blood stream of ffa's real quick,..
