Due to putting a lot of weight on from injection (depo) think it was 3 and half stone,i tried so many different tablets and hardly had any result.so when I seen good reviews about this product I thought I'd give it ago,not everyone is the same but it gave me the energy boast that I needed and made me feel less hungry all the time,I do suggest you drink plenty of water when taking these as it can make you feel dehydrated about from that I had no problems recommended a few people now and they have also got their weight off.i have lost 4 stone and have gone from a U.K. Size 16 to a small 10 or 8 depending where you shop.so i deffo reccomend giving it ago :)
