Hi. Good that you have asked about Endura. We have seen many patients having a weight gain when they take Endura along with exercises , but many have some unexplained problems and particularly after they have stopped. SO the first thing you should do is to consult a Doctor to see there are no hidden diseases not allowing to gain eight. Go for regular exercises and home-made proteins like sprouts, soyabin products , Protein supplements like threptin and such as are known to contain no steroids . Many times if your stature and weight are decided genetically ( meaning you have taken the genetic character of thin relatives) , then it may be very difficult to gain weight.
