The first effects of Green Barley Plus should be visible after about 2-4 weeks of regular use. Of course, the first differences in weight should appear much earlier, but these will be too small to be seen in the mirror. According to official information, the supplement can bring effects of up to 12 kg in 2 months! The effects will also depend on individual predispositions. Some people tend to burn calories quickly, while others need a little more time.
