You need to be patient with this. Make sure you are taking it regularly without fail and abiding by the dosage instructions. The duration required to show the results are relative, but it is advised to wait for a minimum of 180 days. This is also the minimum duration you should wait if you would like to approach the manufacturer for a complete refund on the purchase. Make sure you are also following a healthy diet pattern and workout routine if you would like to get results more efficiently.
