I used to get these on prescription in the uk and they helped me lose weight, I went to buying private as it was easier for me and these unlike many are the genuine item. Since I have been buying these ( excellent price) I have lost a further 1 &a half stone, only another 3 to go!! They absorb fat from the food you eat and it comes out of the body in the normal way (the higher the fat content of the food the brighter the orange colour discharged) They work immediately getting to work on the fat!!
