I had been on eca and clen cycle 2 weeks on 2 weeks off format. I lost significant amount of weight on eca but nothing on clen weeks. I gaved up on clen and I am now only on eca and I am down 25 lbs since I started. my question why didn't my clen work. I took about 4ml(100mcg) a day and yes I get jitters and side effects but no weight loss. I want to try it again. What am I doing wrong? any supplement I need to enhance it. I am confused. Thanks.
