I have used BIO X4 for around three months or more and I did lose weight. I think the product is good for your body. I believe in the product and hope to continue to lose my goal, which is 3 lbs a week. Some weeks I don't make my goal, but so far I have lost 35 lbs. I still have another 60 lb to go to lose all the weight I would like to. I hope it keeps going slow and steady.
Bottom Line: Yes, I would recommend this to a friend
