Never believe in anything like the add of Endura Mass. These are just fake things that are only in the market to attract people. Its type of consumimg capsules while you get trained in a gym. Without the doctors consent never ever have this. One of my friends used to have ot due to his less body weight. After successive consumption of 4momths he realised that it was not affecting any and he stopped. He’s now suffering from lack of haemoglobin in his body. So guys dont ever try these.
