So far so good. I was a bit skeptical at first since fat burning supplements tend to make my heart beat very fast, which makes me very uncomfortable. And so I stop taking this supplement very fast. Also, I’ve never tried anything that would actually help me with appetite. I am doing a keto diet as well as intermitted fasting. And for the last two months I wouldn’t even feel hungry until 2 pm. So seems like it works for me. We’re all different, but since it works for me – I will totally recommend it to people I know and who looks for a supplement that would help with fat burn and appetite.
