Unfortunately, Keppi's energy and stamina aids didn't live up to my expectations. Despite their claims to be industry leaders, the pills did nothing but sap my strength. Although I have a lot of expertise with health products, this was easily the worst encounter I have ever had. Because of this, I was unable to find adequate sports nutrition or a diet that met my requirements as an athlete. Their unresponsive and unhelpful customer care was the icing on the cake. Those in search of hilarity should check out Keppi, but those in search of better health should seek elsewhere.
